Type::IsAbstract Property
Gets a value indicating whether the Type is abstract and must be overridden.
Assembly: mscorlib (in mscorlib.dll)
If the current Type represents a type parameter in the definition of a generic type or generic method, this property always returns false.
The following example returns true if the specified object is abstract; otherwise, it returns false.
using namespace System; using namespace System::Reflection; public ref class AbstractClass abstract { }; public ref class NonAbstractClass { }; int main() { // Check whether the return type of MyAbstractClass is abstract or not. Console::WriteLine("\nChecking whether the type is abstract.\n"); if ((AbstractClass::typeid->IsAbstract)) { Console::WriteLine("The AbstractClass is an abstract class."); } else { Console::WriteLine("The AbstractClass is not an abstract class."); } // Check whether the return type of MyClass is abstract or not. if ((NonAbstractClass::typeid->IsAbstract)) { Console::WriteLine("The NonAbstractClass is an abstract class."); } else { Console::WriteLine("The NonAbstractClass is not an abstract class."); } };
