Definition

Namespace:

System.Xml

Assembly:

System.Xml.ReaderWriter.dll

Converts the supplied String to a DateTimeOffset equivalent.

Overloads

ToDateTimeOffset(String, String[])	Converts the supplied String to a DateTimeOffset equivalent.

ToDateTimeOffset(String)	Converts the supplied String to a DateTimeOffset equivalent.

ToDateTimeOffset(String, String[])

Source:

XmlConvert.cs

Converts the supplied String to a DateTimeOffset equivalent.

public:
 static DateTimeOffset ToDateTimeOffset(System::String ^ s, cli::array <System::String ^> ^ formats);

public static DateTimeOffset ToDateTimeOffset (string s, string[] formats);

static member ToDateTimeOffset : string * string[] -> DateTimeOffset

Public Shared Function ToDateTimeOffset (s As String, formats As String()) As DateTimeOffset

Parameters

s

String

The string to convert.

formats

String[]

An array of formats from which s can be converted. Each format in formats can be any subset of the W3C Recommendation for the XML dateTime type. (For more information, see the dateTime section of the XML Schema specification..) The string s is validated against one of these formats.

Returns

DateTimeOffset

The DateTimeOffset equivalent of the supplied string.

Examples

The following example demonstrates how to read a string from an XML file and use the ToDateTimeOffset method to convert the string to a DateTimeOffset type. The input string must validate against one of the specified formats before being converted.

using System;
using System.Xml;

class Example
{
    static void Main()
    {
        // Create an XmlReader, read to the "time" element, and read contents as type string
        XmlReader reader = XmlReader.Create("transactions.xml");
        reader.ReadToFollowing("time");
        string time = reader.ReadElementContentAsString();

        // Specify formats against which time will be validated before conversion to DateTimeOffset
        // If time does not match one of the specified formats, a FormatException will be thrown.
        // Each specified format must be a subset of the W3C Recommendation for the XML dateTime type
        string[] formats = {"yyyy-MM-ddTHH:mm:sszzzzzzz", "yyyy-MM-ddTHH:mm:ss", "yyyy-MM-dd"};
        try
        {
            // Read the element contents as a string and covert to DateTimeOffset type
            DateTimeOffset transaction_time = XmlConvert.ToDateTimeOffset(time, formats);
            Console.WriteLine(transaction_time);
        }
        catch (Exception e)
        {
            Console.WriteLine(e);
        }
    }
}

Imports System.Xml

Module Module1
    Sub Main()
        ' Create an XmlReader, read to the "time" element, and read contents as type string
        Dim reader As XmlReader = XmlReader.Create("transactions.xml")
        reader.ReadToFollowing("time")
        Dim time As String = reader.ReadElementContentAsString()

        ' Specify formats against which time will be validated before conversion to DateTimeOffset
        ' If time does not match one of the specified formats, a FormatException will be thrown.
        ' Each specified format must be a subset of the W3C Recommendation for the XML dateTime type
        Dim formats As String() = {"yyyy-MM-ddTHH:mm:sszzzzzzz", "yyyy-MM-ddTHH:mm:ss", "yyyy-MM-dd"}
        Try
            ' Read the element contents as a string and covert to DateTimeOffset type
            Dim transaction_time As DateTimeOffset = XmlConvert.ToDateTimeOffset(time, formats)
            Console.WriteLine(transaction_time)
        Catch e As Exception
            Console.WriteLine(e)
        End Try
    End Sub
End Module

The example uses the transactions.xml file.

<?xml version="1.0"?>
<transactions>
   <transaction>
      <id>123456789</id>
      <amount>1.00</amount>
      <currency>USD</currency>
      <time>2007-08-03T22:05:13-07:00</time>
   </transaction>
</transactions>

Remarks

If the offset specified within the input string will cause an overflow in the deserialized representation of the DateTimeOffset, a FormatException is thrown.

When more than seven digits are specified for fractional seconds, the value is rounded. For example, 00000004 becomes 0000000 and 00000005 becomes 0000001.
