CreateInstance() public static method

This method will search internal tables within TypeDescriptor for a TypeDescriptionProvider object that is associated with the given data type. If it finds one, it will delegate the call to that object.

public static CreateInstance ( IServiceProvider provider, Type objectType, Type argTypes, object args ) : object
provider	IServiceProvider
objectType	System.Type
argTypes	System.Type
args	object
return	object
