Gets a value indicating whether the Type is abstract and must be overridden.
Assembly: mscorlib (in mscorlib.dll)
The property returns true in the following cases:
The current type is abstract; that is, it cannot be instantiated, but can only serve as the base class for derived classes. In C#, abstract classes are marked with the abstract (C# Reference) keyword; in Visual Basic, they are marked with the MustInherit (Visual Basic) keyword.
The current type is an interface.
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 creates an array of Type objects that represent the following types:contains type returns true if the specified object is abstract; otherwise, it returns false.
AbstractClass, an abstract class (a class marked as abstract in C# and MustInherit in Visual Basic).
DerivedClass, a class that inherits from AbstractClass.
SingleClass, a non-inheritable class. It is defined as sealed in C# and NotInheritable in Visual Basic.
ITypeInfo, an interface.
ImplementingClass, a class that implements the ITypeInfo interface.
The method returns true only for AbstractClass, the abstract class, and ITypeInfo, the interface.
