C# | Boolean.ToString() Method
This method is used to convert the value of this instance to its equivalent string representation i.e. either “True” or “False”.
Syntax:
public override string ToString ();
Return Value: This method returns “True” (the value of the TrueString property) if the value of this instance is true, or “False” (the value of the FalseString property) if the value of this instance is false.
Below programs illustrate the use of Boolean.ToString() Method:
Example 1:
C#
// C# program to demonstrate // Boolean.ToString() // Method using System; class GFG { // Main Method public static void Main() { // initializing the bool variables bool cat = false ; bool dog = true ; // getting the value of string property string value1 = cat.ToString(); string value2 = dog.ToString(); // print the string property Console.WriteLine( "cat.ToString() returns {0}" , value1); Console.WriteLine( "dog.ToString() returns {0}" , value2); } } |
Output:
cat.ToString() returns False dog.ToString() returns True
Example 2:
C#
// C# program to demonstrate // Boolean.ToString() // Method using System; class GFG { // Main Method public static void Main() { // initializing the bool variables bool alpha = false ; bool beta = true ; bool gamma = true ; bool delta = false ; bool theta = true ; // calling getValue() method getValue(alpha); getValue(beta); getValue(gamma); getValue(delta); getValue(theta); } // defining getValue() method public static void getValue( bool variable) { // getting the value of string property string value = variable.ToString(); // print the string property Console.WriteLine( "{0}" , value); } } |
Output:
False True True False True
Note: XML is case-sensitive, and that the XML specification recognizes “true” and “false” as the valid set of Boolean values. If the string returned by the ToString() method is to be written to an XML file, its String.ToLowerInvariant method should be called first to convert it to lowercase.
