C# | Char.ToLowerInvariant(Char) Method
This method is used to converts the value of a Unicode character to its lowercase equivalent using the casing rules of the invariant culture.
Syntax:
public static char ToLowerInvariant (char c);
Here, c is the Unicode character to convert.
Return Value: This method returns the lowercase equivalent of the c parameter, or the unchanged value of c, if c is already lowercase or not alphabetic.
Below programs illustrate the use of Char.ToLowerInvariant(Char) Method:
Example 1:
// C# program to demonstrate // Char.ToLowerInvariant() // Method using System; class GFG { // Main Method public static void Main() { // calling get() Method get ( 'A' ); get ( 'a' ); get ( 'B' ); get ( 'b' ); } // Defining get() method public static void get ( char c) { // getting Unicode character // using ToLowerInvariant() Method char val = Char.ToLowerInvariant(c); // display the char value Console.WriteLine( "The lowercase equivalent" + " of the {0} is {1}" , c, val); } } |
Output:
The lowercase equivalent of the A is a The lowercase equivalent of the a is a The lowercase equivalent of the B is b The lowercase equivalent of the b is b
Example 2:
// C# program to demonstrate // Char.ToLowerInvariant() // Method using System; class GFG { // Main Method public static void Main() { // declaring and initializing char variable char c = 'A' ; // getting Unicode character // using ToLowerInvariant() Method char val = Char.ToLowerInvariant(c); // display the char value Console.WriteLine( "The lowercase equivalent" + " of the {0} is {1}" , c, val); } } |
Output:
The lowercase equivalent of the A is a
