equivalentCodeEntityop_Explicit(X Element element )

Cast the value of this XElement to a Nullable(Of T) of DateTimeOffset.

This API is not CLS-compliant.

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

Public Shared Narrowing Operator CType (
	element As XElement
) As Nullable(Of DateTimeOffset)

Parameters

element
Type: System.Xml.Linq.XElement

The XElement to cast to an Nullable(Of T) of DateTimeOffset.

Return Value

Type: System.Nullable(Of DateTimeOffset)

A Nullable(Of T) of DateTimeOffset that contains the content of this XElement.

Exception Condition
FormatException

The element does not contain a valid DateTimeOffset value.

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

The following example creates an element with date and time content. It then casts to Nullable(Of T) of DateTimeOffset to retrieve the value.


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

Dim dt As Nullable(Of DateTimeOffset) = CType(root.<Child>(0), Nullable(Of DateTimeOffset))
Console.WriteLine("dt={0}", dt)

This example produces the following output:


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