Last Updated : 11 Jul, 2025

This method is used to converts the value of a Unicode character to its lowercase equivalent using the casing rules of the invariant culture.

public static char ToLowerInvariant (char c);

Here,

is the Unicode character to convert.

This method returns the lowercase equivalent of the

parameter, or the unchanged value of

, if

is already lowercase or not alphabetic. Below programs illustrate the use of

Method:

// 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);
    }
}

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

// 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);
