Return Value

Type: System.Object
The value of the item as the type requested.


The item's value is not in the correct format for the target type.


The attempted cast is not valid.


The attempted cast resulted in an overflow.

When overridden in a derived class, the ValueAs method attempts to convert the value of the item to the .NET Framework version 2.0 type specified.

The IXmlNamespaceResolver object is used to resolve namespace prefixes related to type conversions. For example, when converting an xs:QName to an xs:string.
