Examples
The following example creates an element with date and time content. It then casts to Nullable<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()
StringBuilder output = new StringBuilder();
XElement root = new XElement("Root",
new XElement("Child", new DateTimeOffset(new DateTime(2006, 10, 6, 12, 30, 0)))
);
output.Append(root + Environment.NewLine);
DateTimeOffset? dt = (DateTimeOffset?)root.Element("Child");
output.Append("dt=" + dt + Environment.NewLine);
OutputTextBlock.Text = output.ToString();
