Assembly:  mscorlib (in mscorlib.dll)

public int GetInt32(
	string name
)

Parameters

name
Type: System.String

The name of the value to retrieve.

Return Value

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

ExceptionCondition
ArgumentNullException

name is null.

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.
