static member op_Explicit : System.Xml.Linq.XAttribute -> Nullable<TimeSpan>

Public Shared Narrowing Operator CType (attribute As XAttribute) As Nullable(Of TimeSpan)

Parameters

attribute: XAttribute

The XAttribute to cast to a Nullable<T> of TimeSpan.

Returns

Nullable<TimeSpan>

A Nullable<T> of TimeSpan that contains the content of this XAttribute.

Attributes: CLSCompliantAttribute

Exceptions

FormatException

The attribute does not contain a valid TimeSpan value.

Examples

The following example creates an attribute with time span content. It then retrieves the value by casting to Nullable<T> of TimeSpan.

XElement root = new XElement("Root",  
    new XAttribute("Att", new TimeSpan(1, 5, 30))  
);  
TimeSpan? value = (TimeSpan?)root.Attribute("Att");  
Console.WriteLine("Nullable TimeSpan: value={0}", value == null ? "null" : value.ToString());

Dim root As XElement = <Root Att=<%= New TimeSpan(1, 5, 30) %>/>  
Dim value As Nullable(Of TimeSpan) = CType(root.Attribute("Att"), Nullable(Of TimeSpan))  
Console.WriteLine("Nullable TimeSpan: value={0}", IIf(value.HasValue, value.ToString(), "null"))

This example produces the following output:

Nullable TimeSpan: value=01:05:30

Remarks

The value space of an attribute or element that contains time span content is closely related to duration content as described in ISO 8601. When creating an attribute or element that contains time span content, the attribute or element values are formatted per the W3C specification. Please see the W3C specification for more details.

Behavior is lax when casting to a Nullable<T> of TimeSpan from an attribute or element. Even if the attribute or element value is not formatted exactly per the W3C specification, the value is appropriately converted to a Nullable<T> of TimeSpan.

Returns

Nullable<DateTime>

A Nullable<T> of DateTime that contains the content of this XAttribute.

Exceptions

FormatException

The attribute does not contain a valid DateTime value.

Examples

The following example creates an attribute with a date and time as content. It then retrieves the value by casting to Nullable<T> of DateTime.

Dim value As Nullable(Of DateTime) = CType(root.Attribute("Att"), Nullable(Of DateTime))  
Console.WriteLine("Nullable DateTime: value={0}", IIf(value.HasValue, value.ToString(), "null"))

This example produces the following output:

Nullable DateTime: value=10/6/2006 12:30:00 PM

Remarks

The value space of an attribute or element that contains date and time content is closely related to the dates and times described in ISO 8601. When creating an attribute or element that contains date and time content, the attribute or element values are formatted per the W3C specification. See the W3C specification for more details.

Behavior is lax when casting to a Nullable<T> of DateTime from an attribute or element. Even if the attribute or element value is not formatted exactly per the W3C specification, the value is appropriately converted to a Nullable<T> of DateTime.

This conversion operator uses CultureInfo.InvariantCulture to convert from a DateTime.

Explicit(XAttribute to Nullable<Double>)

Source:: XAttribute.cs

Source:: XAttribute.cs

Source:: XAttribute.cs

Important

This API is not CLS-compliant.

Cast the value of this XAttribute to a Nullable<T> of Double.

public:
 static explicit operator Nullable<double>(System::Xml::Linq::XAttribute ^ attribute);

[System.CLSCompliant(false)]
public static explicit operator double?(System.Xml.Linq.XAttribute attribute);

[System.CLSCompliant(false)]
public static explicit operator double?(System.Xml.Linq.XAttribute? attribute);

[<System.CLSCompliant(false)>]
static member op_Explicit : System.Xml.Linq.XAttribute -> Nullable<double>

Public Shared Narrowing Operator CType (attribute As XAttribute) As Nullable(Of Double)

Parameters

attribute: XAttribute

The XAttribute to cast to Nullable<T> of Double.

Returns

Nullable<Double>

A Nullable<T> of Double that contains the content of this XAttribute.

Attributes: CLSCompliantAttribute

Exceptions

FormatException

The attribute does not contain a valid Double value.

Examples

The following example creates an attribute with double precision floating point content. It then retrieves the value by casting to Nullable<T> of Double.

XElement root = new XElement("Root",  
    new XAttribute("Att", 1.79769313486231e308)  
);  
double? value = (double?)root.Attribute("Att");  
Console.WriteLine("Nullable double: value={0}", value == null ? "null" : value.ToString());

Dim root As XElement = <Root Att="1.79769313486231E+308"/>  
Dim value As Nullable(Of Double) = CType(root.Attribute("Att"), Nullable(Of Double))  
Console.WriteLine("Nullable double: value={0}", IIf(value.HasValue, value.ToString(), "null"))

This example produces the following output:

Nullable double: value=1.79769313486231E+308

This API is not CLS-compliant.

Cast the value of this XAttribute to a DateTimeOffset.

public:
 static explicit operator DateTimeOffset(System::Xml::Linq::XAttribute ^ attribute);

[System.CLSCompliant(false)]
public static explicit operator DateTimeOffset(System.Xml.Linq.XAttribute attribute);

[<System.CLSCompliant(false)>]
static member op_Explicit : System.Xml.Linq.XAttribute -> DateTimeOffset

Public Shared Narrowing Operator CType (attribute As XAttribute) As DateTimeOffset

Parameters

attribute: XAttribute

The XAttribute to cast to DateTimeOffset.

Returns

DateTimeOffset

A DateTimeOffset that contains the content of this XAttribute.

Attributes: CLSCompliantAttribute

Exceptions

FormatException

The attribute does not contain a valid DateTimeOffset value.

ArgumentNullException

The attribute parameter is null.

Examples

The following example creates an attribute with date and time content. It then casts it to DateTimeOffset to retrieve the value.

XElement root = new XElement("Root",  
    new XAttribute("Att", new DateTimeOffset(new DateTime(2006, 10, 6, 12, 30, 0)))  
);  
Console.WriteLine(root);  

// casting from a strictly formatted XML attribute  
DateTimeOffset dt = (DateTimeOffset)root.Attribute("Att");  
Console.WriteLine("dt={0}", dt);

Dim root As XElement = _  
    <Root  
        Att=<%= New DateTimeOffset(New DateTime(2006, 10, 6, 12, 30, 0)) %>/>  
Console.WriteLine(root)  

' casting from a strictly formatted XML attribute  
Dim dt As DateTimeOffset = CType(root.Attribute("Att"), DateTimeOffset)  
Console.WriteLine("dt={0}", dt)

This example produces the following output:

<Root Att="2006-10-06T12:30:00-07:00" />  
dt=10/6/2006 12:30:00 PM -07:00

Remarks

This conversion operator uses the XmlConvert class to do the conversion.

Explicit(XAttribute to DateTime)

Source:: XAttribute.cs

Source:: XAttribute.cs

Source:: XAttribute.cs

Important

This API is not CLS-compliant.

Cast the value of this XAttribute to a DateTime.

public:
 static explicit operator DateTime(System::Xml::Linq::XAttribute ^ attribute);

[System.CLSCompliant(false)]
public static explicit operator DateTime(System.Xml.Linq.XAttribute attribute);

[<System.CLSCompliant(false)>]
static member op_Explicit : System.Xml.Linq.XAttribute -> DateTime

Public Shared Narrowing Operator CType (attribute As XAttribute) As DateTime

Parameters

attribute: XAttribute

The XAttribute to cast to DateTime.

Returns

DateTime

A DateTime that contains the content of this XAttribute.

Attributes: CLSCompliantAttribute

Exceptions

FormatException

The attribute does not contain a valid DateTime value.

ArgumentNullException

The attribute parameter is null.

Examples

The following example creates an attribute with date and time content. It then casts it to DateTime to retrieve the value.

// Behavior is strict when formatting an XML element or attribute from a DateTime,  
// but behavior is lax when casting to a DateTime from an element or attribute.  

XElement root = new XElement("Root",  
    new XAttribute("Att", new DateTime(2006, 10, 6, 12, 30, 0))  
);  
Console.WriteLine(root);  

// casting from a strictly formatted XML attribute  
DateTime dt = (DateTime)root.Attribute("Att");  
Console.WriteLine("dt={0}", dt);  
Console.WriteLine("-----");  

// if root is formatted in some different way than the standard ISO 8601, if at all possible,  
// the value is appropriately converted to DateTime  

XAttribute dtAtt = new XAttribute("OrderDate", "October 6, 2006");  
Console.WriteLine(dtAtt);  
DateTime orderDate = (DateTime)dtAtt;  
Console.WriteLine("OrderDate={0:d}", orderDate);

' Behavior is strict when formatting an XML element or attribute from a DateTime,  
' but behavior is lax when casting to a DateTime from an element or attribute.  
Dim root As XElement = <Root Att=<%= New DateTime(2006, 10, 6, 12, 30, 0) %>/>  

Console.WriteLine(root)  

' casting from a strictly formatted XML attribute  
Dim dt As DateTime = CType(root.Attribute("Att"), DateTime)  
Console.WriteLine("dt={0}", dt)  
Console.WriteLine("-----")  

' if root is formatted in some different way than the standard ISO 8601, if at all possible,  
' the value is appropriately converted to DateTime  
Dim dtAtt As XAttribute = New XAttribute("OrderDate", "October 6, 2006")  
Console.WriteLine(dtAtt)  
Dim orderDate As DateTime = CType(dtAtt, DateTime)  
Console.WriteLine("OrderDate={0:d}", orderDate)

This example produces the following output:

<Root Att="2006-10-06T12:30:00" />  
dt=10/6/2006 12:30:00 PM  
-----  
OrderDate="October 6, 2006"  
OrderDate=10/6/2006

Remarks

Behavior is lax when casting to a DateTime from an attribute or element. Even if the attribute or element value is not formatted exactly per the W3C specification, the value is appropriately converted to a DateTime.

This conversion operator uses CultureInfo.InvariantCulture to convert from a DateTime.

 static explicit operator bool(System::Xml::Linq::XAttribute ^ attribute);

[System.CLSCompliant(false)]
public static explicit operator bool(System.Xml.Linq.XAttribute attribute);

[<System.CLSCompliant(false)>]
static member op_Explicit : System.Xml.Linq.XAttribute -> bool

Public Shared Narrowing Operator CType (attribute As XAttribute) As Boolean

Parameters

attribute: XAttribute

The XAttribute to cast to Boolean.

Returns

Boolean

A Boolean that contains the content of this XAttribute.

Attributes: CLSCompliantAttribute

Exceptions

FormatException

The attribute does not contain a valid Boolean value.

ArgumentNullException

The attribute parameter is null.

Examples

The following example creates an attribute with a Boolean value, then casts it to Boolean.

XElement root = new XElement("Root",   
    new XAttribute("BoolValue", true)  
);  
bool bv = (bool)root.Attribute("BoolValue");  
Console.WriteLine("(bool)BoolValue={0}", bv);

Dim root As XElement = <root BoolValue="true"/>  
Dim bv As Boolean = CBool(root.Attribute("BoolValue"))  
Console.WriteLine("(bool)BoolValue={0}", bv)

This example produces the following output:

(bool)BoolValue=True

Remarks

When converting to Boolean from an attribute or element, allowed values are "0", "1", and any string that produces "true" or "false" after trimming and conversion to lower case.
