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.

        // 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:

9213128 is not equal to 2131978

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.
