- The method "ToLower" of char class takes argument of type char.
- The argument "ch" is a character.
- The method returns the lowercase equivalent of "ch".
- The general syntax of the method ToLower of char type is as follows:
char.ToLower (‘A’);
Step 2
Case 1:

//declare a variable uppercase of type char
char uppercase ='A';
//convert uppercase char to lowercase char
