Examples

The following example creates an element with date and time content. It then casts to 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 DateTimeOffset = CType(root.<Child>(0), 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();
