XmlTextAttribute.DataType Property

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Gets or sets the XML Schema definition (XSD) language data type of the text generated by the XmlSerializer.

Namespace:  System.Xml.Serialization
Assembly:  System.Xml (in System.Xml.dll)

Syntax

'Declaration
Public Property DataType As String
public string DataType { get; set; }

Property Value

Type: System.String
An XML Schema (XSD) data type, as defined by the World Wide Web Consortium (www.w3.org) document, XML Schema Part 2: Datatypes.

Exceptions

Exception Condition
Exception

The XML Schema data type you have specified cannot be mapped to the .NET data type.

InvalidOperationException

The XML Schema data type you have specified is invalid for the property and cannot be converted to the member type.

Remarks

Setting the DataType property to an XML Schema simple data type affects the format of the generated XML. For example, setting the property to "date" causes the generated text to be formatted in the general date style, for example: 2001-08-31. By contrast, setting the property to "dateTime" results in a specific instant as defined by the International Organization for Standardization document 8601, "Representations of Dates and Times", for example: 2001-08-15T06:59:11.0508456-07:00.

For the XML Schema base64Binary and hexBinary data types, use an array of Byte structures, and apply a XmlTextAttribute with the DataType set to "base64Binary" or "hexBinary", as appropriate. For the XML Schema time and date data types, use the DateTime type and apply the XmlTextAttribute with the DataType set to "date" or "time".

For every XML Schema data type that is mapped to a string, apply the XmlTextAttribute with its DataType property set to the XML Schema data type. Note that this does not change the serialization format, only the schema for the member.

NoteNote:

The property is case-sensitive, so you must set it exactly to one of the XML Schema data types.

NoteNote:

Passing binary data as an XML element is more efficient than passing it as an XML attribute.
