UInt64.Equals Method in C# with Examples Last Updated : 11 Jul, 2025 Summarize Comments Improve Suggest changes Share Like Article Like Report 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 Reference: https://learn.microsoft.com/en-us/dotnet/api/system.uint64.equals?view=netstandard-2.1 Comment More infoAdvertise with us Next Article UInt32.Equals Method in C# with Examples K Kirti_Mangal Follow Improve Article Tags : C# CSharp-method CSharp-UInt64-Struct Similar Reads UInt16.Equals Method in C# with Examples UInt16.Equals Method is used to get a value which indicates whether the current instance is equal to a specified object or 16-bit unsigned integer or not.
