Type::IsAssignableFrom Method
Determines whether an instance of the current Type can be assigned from an instance of the specified Type.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Parameters
- c
- Type: System::Type
The Type to compare with the current Type.
Return Value
Type: System::Booleantrue if c and the current Type represent the same type, or if the current Type is in the inheritance hierarchy of c, or if the current Type is an interface that c implements, or if c is a generic type parameter and the current Type represents one of the constraints of c. false if none of these conditions are true, or if c is nullptr.
This method can be overridden by a derived class.
Note: |

A generic type definition is not assignable from a closed constructed type. That is, you cannot assign the closed constructed type MyGenericList<int> (MyGenericList(Of Integer) in Visual Basic) to a variable of type MyGenericList<T>. |
You can determine the element types of a Type using GetElementType.
If the c parameter is of type TypeBuilder, the result is based on the type that is to be built. The following code example demonstrates this using a built type named B.
TypeBuilder b1 = moduleBuilder.DefineType("B", TypeAttributes.Public, typeof(A));
// Returns true:
typeof(A).IsAssignableFrom(b1))
The following example demonstrates the IsAssignableFrom method using defined classes, integer arrays, and generics.
