Assembly: System.Configuration (in system.configuration.dll)
The SubclassTypeValidator class is used to ensure that an object meets specific criteria. The criteria for validation is established when an instance of the SubclassTypeValidator class is created.
The CanValidate method determines whether the type of the object being validated is in fact a Type. The object being validated is passed as a parameter of the Validate method. This method first verifies that the object to validate is not a null reference (Nothing in Visual Basic), and then verifies that the object is a derived class of the expected type.
