UInt64.CompareTo() Method in C# with Examples

UInt64.CompareTo Method is used to compare the current instance to a specified object or another UInt64 instance. It returns an integer which shows whether the value of the current instance is less than, equal to, or greater than the value of the specified object or the other UInt64 instance. There are 2 methods in the overload list of this method as follows:

  • CompareTo(UInt64) Method
  • CompareTo(Object) Method

UInt64.CompareTo(UInt64) Method

This method is used to compare the current instance to a specified 64-bit unsigned long integer and returns an integer which shows whether the value of the current instance is less than, equal to, or greater than the value of the specified 64-bit unsigned long integer.



Syntax:

public int CompareTo (ulong value);

Here, it takes an unsigned long value to compare.

Return Value: It returns a 32-bit signed number indicating the relative values of current instance and value parameter as follows:

  • Less than Zero: if Current Instance < value
  • Zero: if Current Instance = value
  • Greater than Zero: if Current Instance > value

        // checking the status
        if (status > 0)
            Console.WriteLine("{0} is greater than {1}",
                                        value1, value2);
        else if (status < 0)
            Console.WriteLine("{0} is less than {1}",
                                     value1, value2);
        else
            Console.WriteLine("{0} is equal to {1}",
                                    value1, value2);
    }
}

UInt64.CompareTo(Object) Method

This method is used to compare the current instance to a specified object and returns an integer which indicates whether the value of the current instance is less than, equal to, or greater than the value of the object.

Syntax:


public int CompareTo (object value);

Here, it takes the object to compare with this instance, or null.

Return Value: It returns a 32-bit signed number indicating the relative values of current instance and value parameter as follows:

  • Less than Zero: if Current Instance < value
  • Zero: if Current Instance = value
  • Greater than Zero: if Current Instance > value

Exception: It throws ArgumentException if value is not a UInt64.
