Implements

_Type::IsAbstract

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.");
    }
};
