InstantiateType() public static method

Instantiates the type using the assembly specified to load the type.
This is a convenience in the case of needing to instantiate a type but not wanting to specify in the string the version, culture and public key token.
/// If the or is /// /// If cannot load the type from the assembly or the call to InstantiateType(Type) fails. ///
public static InstantiateType ( Assembly assembly, string typeName ) : object
assembly System.Reflection.Assembly The assembly.
typeName string Name of the type.
