C#.Net Character

The System.Char data type is used to hold a single, Unicode character. It can be any small letter (a, b, c, …), any capital letter (A, B, C, …), any single digit (0, 1, 2,…) and special character (!, @, $, +, —, …) etc., all are treated as characters. To assign a character, you simply need to put them inside single quotes(''). For example: char ch = 'a';

Example 1: Input character and display it.

static void Main(string[] args)
{
    char ch;
    Console.Write("Enter Character: ");
    ch = Console.ReadKey(true).KeyChar; //input char is hidden
    Console.WriteLine("Character = " + ch);
    
    Console.Write("Enter Character: ");
    ch = Console.ReadKey().KeyChar; //input char is visible
    Console.WriteLine("Character = " + ch);
    Console.ReadLine();
}

Example 2: Input character and display it.

static void Main(string[] args)
{
    char ch;
    Console.Write("Enter Character: ");
    ch = Convert.ToChar(Console.ReadLine());
    Console.WriteLine("Character = " + ch);
    Console.ReadLine();
}
