UInt64.Equals Method (UInt64)

Returns a value indicating whether this instance is equal to a specified UInt64 value.

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

public bool Equals(
	ulong obj


Type: System.UInt64

A UInt64 value to compare to this instance.

Return Value

Type: System.Boolean
true if obj has the same value as this instance; otherwise, false.



This method implements the System.IEquatable<T> interface, and performs slightly better than Equals because it does not have to convert the obj parameter to an object.

The following example demonstrates the Equals method.

using System;

class Example
     public static void Main()
         UInt64 value1 = 50;
         UInt64 value2 = 50;

         // Display the values.
        Console.WriteLine("value1:   Type: {0}   Value: {1}",
                          value1.GetType().Name, value1);
        Console.WriteLine("value2:   Type: {0}   Value: {1}",
                        value2.GetType().Name, value2);

        // Compare the two values.
        Console.WriteLine("value1 and value2 are equal: {0}",
// The example displays the following output: 
//       value1:   Type: UInt64   Value: 50 
//       value2:   Type: UInt64   Value: 50 
//       value1 and value2 are equal: True
