Type: System.Xml.Linq.XElement
The XElement to cast to Nullable(Of T) of Single.

Return Value

Type: System.Nullable(Of Single)
A Nullable(Of T) of Single that contains the content of this XElement.


The element does not contain a valid Single value.

The following example creates an element with single precision floating point content. It then retrieves the value by casting to Nullable(Of T) of Single.

Dim output As New StringBuilder
Dim root As XElement = _
Dim value As Nullable(Of Single) = CType(root.Element("Value"), Nullable(Of Single))
output.Append(String.Format("Nullable Single: value={0}", IIf(value.HasValue, _
    value.ToString(), "null")))
OutputTextBlock.Text = output.ToString()
