C# | Boolean.CompareTo(Object) Method
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
