XmlConvert.ToDateTimeOffset Method (String, String)

Converts the supplied String to a DateTimeOffset equivalent.

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

public static DateTimeOffset ToDateTimeOffset(
	string s,
	string format


Type: System.String
The string to convert.
Type: System.String
The format from which s is converted. The format parameter can be any subset of the W3C Recommendation for the XML dateTime type. For more information see XML Schema Part 2: Datatypes. The string s is validated against this format.

Return Value

Type: System.DateTimeOffset
The DateTimeOffset equivalent of the supplied string.


s is null.


s or format is an empty string or is not in the specified format.

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.

String xmlString =
    @"<?xml version='1.0'?>

StringBuilder output = new StringBuilder();

// Create an XmlReader
using (XmlReader reader = XmlReader.Create(new StringReader(xmlString)))
    string time = reader.ReadElementContentAsString();

    // Specify a format against which time will be validated before conversion to DateTimeOffset
    // If time does not match the format, a FormatException will be thrown.
    // The specified format must be a subset of the W3C Recommendation for the XML dateTime type
    string format = "yyyy-MM-ddTHH:mm:sszzzzzzz";
        // Read the element contents as a string and covert to DateTimeOffset type
        DateTimeOffset transaction_time = XmlConvert.ToDateTimeOffset(time, format);
    catch (Exception e)
// Display the output to the TextBlock control
OutputTextBlock.Text = output.ToString();
