Return Value

Type: System.Int32
The 32-bit signed integer associated with name.

ExceptionCondition
ArgumentNullException

name is Nothing.

InvalidCastException

The value associated with name cannot be converted to a 32-bit signed integer.

SerializationException

An element with the specified name is not found in the current instance.

If the value is a 32-bit signed integer, or can be converted to one, that value is returned; otherwise, a InvalidCastException is thrown. All conversions are done by the IFormatterConverter associated with this SerializationInfo.
