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