C# Convert.ToInt32(char) Method

Convert.ToInt32(char) Method is used to convert a specific char value to its equivalent integer (int 32 signed number) (It can also be known as ASCII value).

Syntax:

    int Convert.ToInt32(char value);

It accepts a char value/variable as an argument and returns its equivalent signed integer.

Example:

    Input: 
    char a = 'A';
    Output:
    65

Code:

using System;
using System.Text;

namespace ConsoleApplication3
{
    class Program
    {
        static void Main(string[] args)
        {

            char a = 'A'; //uppercase A
            char b = 'z'; //lowercase z

            Console.WriteLine("value of a: {0}, type of a: {1}", a, a.GetType());
            Console.WriteLine("value of b: {0}, type of b: {1}", b, b.GetType());

            //converting to Int32 & printing values & types

            Console.WriteLine("value: {0}, type: {1}", Convert.ToInt32(a), Convert.ToInt32(a).GetType());
            Console.WriteLine("value: {0}, type: {1}", Convert.ToInt32(b), Convert.ToInt32(b).GetType());

            //hit ENTER to exit
            Console.ReadLine();
        }
    }
}

Output

value of a: A, type of a: System.Char
value of b: z, type of b: System.Char
value: 65, type: System.Int32
value: 122, type: System.Int32
