Type::GetGenericParameterConstraints Method

Returns an array of Type objects that represent the constraints on the current generic type parameter.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

No code example is currently available or this language may not be supported.

Return Value

Type: array<System::Type>
An array of Type objects that represent the constraints on the current generic type parameter.

ExceptionCondition
InvalidOperationException

The current Type object is not a generic type parameter. That is, the IsGenericParameter property returns false.

Each constraint on a generic type parameter is expressed as a Type object. Use the IsClass property to determine whether a constraint is the base class constraint; if the property returns false, the constraint is an interface constraint. If a type parameter has no class constraint and no interface constraints, an empty array is returned.

For a list of the invariant conditions for terms used in generic reflection, see the IsGenericType property remarks.

The following code example defines a generic type Test with two type parameters that have different constraints. When the program executes, the constraints are examined using the GenericParameterAttributes property and the GetGenericParameterConstraints method.
