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

'Declaration
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.

ExceptionCondition
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 output As New StringBuilder
Dim root As XElement = _
    <Root>
        <Child><%= New DateTimeOffset(New DateTime(2006, 10, 6, 12, 30, 0)) %></Child>
    </Root>
output.Append(root)
output.Append(Environment.NewLine)

Dim dt As Nullable(Of DateTimeOffset) = CType(root.<Child>(0), Nullable(Of DateTimeOffset))
output.Append(String.Format("dt={0}", dt))
output.Append(Environment.NewLine)

OutputTextBlock.Text = output.ToString()
