C# | Boolean.CompareTo(Object) Method

Last Updated : 23 Apr, 2019

Boolean.CompareTo(Object) Method is used to compare the current instance to a specified object and returns an integer which shows their relationship to one another.

Syntax:

public int CompareTo (object obj);

Here, it takes an object to compare to current instance or null.

Return Value: This method returns a signed integer which shows the relative order of the current instance and obj.

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

Exception: It throws ArgumentException if obj is not an Boolean.

Example 1:

// C# program to demonstrate the 
// Boolean.CompareTo(Object) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Declaring and initializing value1 
            bool value1 = true; 
  
            // Declaring and initializing value2 
            object value2 = true; 
  
            // using CompareTo() method 
            int status = value1.CompareTo(value2); 
  
            // 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); 
        } 
  
        catch (ArgumentException e)  
        { 
            Console.WriteLine("value2 must be Boolean"); 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
} 

Output:

True is equal to True

Example 2: For ArgumentException

// C# program to demonstrate the 
// Boolean.CompareTo(Object) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Declaring and initializing value1 
            bool value1 = true; 
  
            // Declaring and initializing value2 
            object value2 = 53554; 
  
            // using CompareTo() method 
            int status = value1.CompareTo(value2); 
  
            // 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); 
        } 
  
        catch (ArgumentException e)  
        { 
            Console.WriteLine("value2 must be Boolean"); 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
} 

Output:

value2 must be Boolean
Exception Thrown: System.ArgumentException
