C# Type IsSubclassOf

Description

Type IsSubclassOf determines whether the class represented by the current Type derives from the class represented by the specified Type.

Syntax

Type.IsSubclassOf has the following syntax.

[ComVisibleAttribute(true)]
public virtual bool IsSubclassOf(
  Type c
)

Parameters

Type.IsSubclassOf has the following parameters.

• c - The type to compare with the current type.

Returns

Type.IsSubclassOf method returns true if the Type represented by the c parameter and the current Type represent classes, and the class represented by the current Type derives from the class represented by c; otherwise, false. This method also returns false if c and the current Type represent the same class.

Example

The following example demonstrates the use of the IsSubclassOf method by creating an instance of a class and an instance of its derived class.

/*from www. j a  va2  s  .c o  m*/
using System;

public class Class1 { }
public class DerivedC1 : Class1 { }

class IsSubclassTest
{
    public static void Main()
    {
        Class1 myClass = new Class1();
        DerivedC1 myDClass = new DerivedC1();
        Type myClassType = myClass.GetType();
        Type myDClassType = myDClass.GetType();

        Console.WriteLine(myDClassType.IsSubclassOf(myClassType));
    }
}

The code above generates the following result.
