UInt64.Equals Method in C# with Examples
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:
// 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); } } |
5232642 is not equal to 2317648
Example 2:
// 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); } } |
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:
// 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); } } |
13421227 is not equal to 0
Example 2:
// 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); } } |
1231264 is not equal to 7234455 1423412 is not equal to 14432314 7742344 is equal to 7742344 5443 is not equal to 7346
