Type.Equals Method (Object)

Determines if the underlying system type of the current Type is the same as the underlying system type of the specified Object.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public override bool Equals(
	Object o
)

Parameters

o
Type: System.Object

The object whose underlying system type is to be compared with the underlying system type of the current Type.

Return Value

Type: System.Boolean
true if the underlying system type of o is the same as the underlying system type of the current Type; otherwise, false. This method also returns false if the object specified by the o parameter is not a Type.

Implements

_Type.Equals(Object)
_MemberInfo.Equals(Object)

This method overrides Object.Equals.

The following example uses Equals to compare two Object instances.


using System;
using System.Reflection;

class Example
{
    public static void Main()
    {

        Type a = typeof(System.Object);
        Type b = typeof(System.Object);

        Console.WriteLine("{0} == {1}: {2}", a, b, a.Equals(b));

        // The Type objects in a and b are equal, 
        // because they represent System.Object.

        a = typeof(Example);
        b = new Example().GetType();

        Console.WriteLine("{0} is equal to {1}: {2}", a, b, a.Equals(b));

        // The Type objects in a and b are equal, 
        // because they both represent type Example.

        b = typeof(Object);

        Console.WriteLine("typeof({0}).Equals(typeof({1})): {2}", a, b, a.Equals(b));

        // The Type objects in a and b are not equal, 
        // because variable a represents type Example 
        // and variable b represents type Object. 

        //Console.ReadLine();

    }
}

// 
/* This code example produces the following output:
    System.Object == System.Object: True
    Example is equal to Example: True
    typeof(Example).Equals(typeof(System.Type)): False
