Uri.ReferenceEquals() Method in C# with Examples

Uri.ReferenceEquals() Method is used to check the reference of two specified objects. This method can be overridden and static in nature. So, if a user is going to test the two objects references for equality and he is not sure about the implementation of the Equals method, then he can call the ReferenceEquals method.

Syntax: bool Uri.ReferenceEquals (Uri uri1, Uri uri2);

Parameters:
uri1: It is the first uri to compare.
uri2: It is the second uri to compare.

Return Value: This method returns true if reference of two objects are equal otherwise it returns false.

Below programs illustrate the use of Uri.ReferenceEquals()  Method:

Example 1:

C#

// C# program to demonstrate the
// Uri.ReferenceEquals() Method
using System;
using System.Globalization;

class GFG {

     // Main Method
    public static void Main()
    {
        // Declaring and initializing value1
        Uri  v1 = null;

        // Declaring and initializing value2
        Uri  v2 = null;

        // using ReferenceEquals(Uri ,
        // Uri ) method
        bool status = Uri.ReferenceEquals(v1, v2);

        // checking the status
        if (status)
            Console.WriteLine("null is equal to null");
        else
            Console.WriteLine("null is not equal to null");
    }
}

Output:

null is equal to null

Example 2:

C#

// C# program to demonstrate the
// Uri.ReferenceEquals() Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {

        Uri  p = new Uri("https://www.geeksforgeeks.org/index.htm");
        Uri  q = null;

        // calling get() method
        get(p, null);

        // assigning p to q
        q = p;
        get(p, q);
        get(q, null);
    }

    // defining get() method
    public static void get(Uri  v1,
                           Uri  v2)
    {

        // using ReferenceEquals() method
        bool status = Uri.ReferenceEquals(v1, v2);

        // checking the status
        if (status)
            Console.WriteLine("{0} is equal to {1}",
                                            v1, v2);
        else
            Console.WriteLine("{0} is not equal to {1}",
                                                v1, v2);
    }
}

Output:

https://www.geeksforgeeks.org/index.htm is not equal to 
https://www.geeksforgeeks.org/index.htm is equal to https://www.geeksforgeeks.org/index.htm
https://www.geeksforgeeks.org/index.htm is not equal to 

Note: Here, null will never be printed in the output.
