ContainsGenericParameters Property

MethodBase.ContainsGenericParameters Property


Gets a value indicating whether the generic method contains unassigned generic type parameters.

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

Public Overridable ReadOnly Property ContainsGenericParameters As Boolean

Property Value

Type: System.Boolean

true if the current MethodBase object represents a generic method that contains unassigned generic type parameters; otherwise, false.

A generic method can be invoked only if there are no generic type definitions or open constructed types in the type arguments of the method itself or in any enclosing types. Because types can be arbitrarily complex, making this recursive determination is difficult. For convenience, and to reduce the chance of error, the ContainsGenericParameters property provides a standard way to distinguish between closed constructed methods, which can be invoked, and open constructed methods, which cannot. If the ContainsGenericParameters property returns true, the method cannot be invoked.

The ContainsGenericParameters property searches recursively for type parameters. For example, it returns true for any method in an open type A<T> (A(Of T) in Visual Basic), even though the method itself is not generic. Contrast this with the behavior of the IsGenericMethod property, which returns false for such a method.

Similarly, the ContainsGenericParameters property parameter returns true for any constructor in an open type, even though constructors cannot have type parameters of their own.

For a list of the invariant conditions for terms specific to generic methods, see the MethodInfo.IsGenericMethod property. For a list of the invariant conditions for other terms used in generic reflection, see the Type.IsGenericType property.
