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
