UInt64.Equals Method in C# with Examples

Last Updated : 01 May, 2019

UInt64.Equals Method is used to get a value which indicates whether the current instance is equal to a specified object or 64-bit unsigned long integer or not. There are 2 methods in the overload list of this method as follows:

Equals(UInt64) Method

Equals(Object) Method

UInt64.Equals(UInt64) Method

This method is used to return a value indicating whether the current instance is equal to a specified 64-bit unsigned long integer value or not.

Syntax: public bool Equals (ulong obj); Here, it takes a 64-bit unsigned long integer value to compare to the current instance. Return Value: This method returns true if obj has the same value as this instance otherwise, false.

Below programs illustrate the use of UInt64.Equals(UInt64) Method: Example 1:

csharp

// C# program to demonstrate the
// UInt64.Equals(UInt64) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        // Declaring and initializing value1
        ulong value1 = 5232642;

        // Declaring and initializing value2
        ulong value2 = 2317648;

        // using Equals(UInt64) method
        bool status = value1.Equals(value2);

        // checking the status
        if (status)
            Console.WriteLine("{0} is equal to {1}",
                                    value1, value2);
        else
            Console.WriteLine("{0} is not equal to {1}",
                                        value1, value2);
    }
}

Output:

5232642 is not equal to 2317648

Example 2:

csharp

// C# program to demonstrate the
// UInt64.Equals(UInt64) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {

        // calling get() method
        get(9213128, 2131978);
        get(656455, 656455);
        get(10120, 10120);
        get(UInt64.MaxValue, UInt64.MinValue);
    }

    // defining get() method
    public static void get(ulong value1,
                           ulong value2)
    {

        // using Equals(UInt64) method
        bool status = value1.Equals(value2);

        // checking the status
        if (status)
            Console.WriteLine("{0} is equal to {1}",
                                    value1, value2);
        else
            Console.WriteLine("{0} is not equal to {1}",
                                        value1, value2);
    }
}

Output:

9213128 is not equal to 2131978
656455 is equal to 656455
10120 is equal to 10120
18446744073709551615 is not equal to 0

UInt64.Equals(Object) Method

This method is used to returns a value indicating whether the current instance is equal to a specified object or not.

Syntax: public override bool Equals (object obj); Here, it takes an object to compare with the current instance. Return Value: This method returns true if obj is an instance of UInt64 and equals the value of this instance otherwise, false.

Below programs illustrate the use of the above-discussed method: Example 1:

csharp

// C# program to demonstrate the
// UInt64.Equals(Object) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        // Declaring and initializing value1
        ulong value1 = 13421227;

        // Declaring and initializing value2
        object value2 = 1 / 417;

        // using Equals(object) method
        bool status = value1.Equals(value2);

        // checking the status
        if (status)
            Console.WriteLine("{0} is equal to {1}",
                                    value1, value2);
        else
            Console.WriteLine("{0} is not equal to {1}",
                                        value1, value2);
    }
}

Output:

13421227 is not equal to 0

Example 2:

csharp

// C# program to demonstrate the
// UInt64.Equals(Object) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        // calling get() method
        get(1231264, 7234455);
        get(1423412, (ulong)14432314);
        get(7742344, (ulong)7742344);
        get(5443, 7346);
    }

    // defining get() method
    public static void get(ulong value1,
                           object value2)
    {

        // using Equals(object) method
        bool status = value1.Equals(value2);

        // checking the status
        if (status)
            Console.WriteLine("{0} is equal to {1}",
                                    value1, value2);
        else
            Console.WriteLine("{0} is not equal to {1}",
                                        value1, value2);
    }
}

Output:

1231264 is not equal to 7234455
1423412 is not equal to 14432314
7742344 is equal to 7742344
5443 is not equal to 7346
