Validates that an object is a derived class of a specified type.
Assembly: System.Configuration (in System.Configuration.dll)
Thetype exposes the following members.
|CanValidate||Determines whether an object can be validated based on type. (Overrides ConfigurationValidatorBase.CanValidate(Type).)|
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|
|GetHashCode||Serves as the default hash function. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|Validate||Determines whether the value of an object is valid. (Overrides ConfigurationValidatorBase.Validate(Object).)|
The class is used to ensure that an object meets specific criteria. The criteria for validation is established when an instance of the 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.
