Gets a value indicating whether the generic method contains unassigned generic type parameters.
Assembly: mscorlib (in mscorlib.dll)
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 property provides a standard way to distinguish between closed constructed methods, which can be invoked, and open constructed methods, which cannot. If the property returns true, the method cannot be invoked.
The 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 property parameter returns true for any constructor in an open type, even though constructors cannot have type parameters of their own.
