C# | Boolean.CompareTo(Boolean) Method

Boolean.CompareTo(Boolean) Method is used to compare the current instance to a specified Boolean object and returns an indication of their relative values.

Syntax:

public int CompareTo (bool value);

Here, the value is a Boolean object to compare to the current instance.

Return Value: This method returns a 32-bit signed integer that indicates the relative order of this instance and value. 

• Less than zero: If this instance is false and value is true.
• Zero: If this instance and value are equal (either both are true or both are false).
• Greater than zero: If this instance is true and value is false.

Example:

C#

// C# program to demonstrate
// Boolean.CompareTo(Boolean)
// Method
using System;

class GFG {

    // Main Method
    public static void Main()
    {

        // Declaring val1 and val2
        bool val1, val2;

        // initializing the val1,
        // and val2
        val1 = true;
        val2 = false;

        // using CompareTo method
        int i = val2.CompareTo(val1);

        // checking the condition
        if (i > 0)
            Console.Write("val2 is greater than val1");

        else if (i < 0)
            Console.Write("val2 is less than val1");

        else
            Console.Write("val1 is equal to val1");
    }
}

Output:

val2 is less than val1
