C# Chars Example | Chars | Source Code

Purpose: – Illustrates the C# Syntax for Chars.

using System;
public class clsChars
{
 
    public void Main()
    {
 
 
        //****************************************************************************************
        // Example #1: Chars(index)
        // Gets the character at the specified index - index is 0 based
        //****************************************************************************************
 
        Console.WriteLine("Example #1: Chars(index) ");
 
        string strCharsExample = "ABC";
 
        // Return Uppercase
        Console.WriteLine(strCharsExample[1]); // Returns B
 
        //write blank line to make output easier to read
        Console.WriteLine();
 
 
 
        //Prevent console from closing before you press enter
        Console.ReadLine();
 
    }
 
 
}

Step 2: Click on C# to Cut-n-paste code into Program.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
 
namespace CSharp_Syntax
{
    class Program
    {
        static void Main(string[] args)
        {
 
 
            clsChars myChars = new clsChars();
            myChars.Main();
 
        }
    }
}

Prerequistes:

1. Install C# (Express or Standard Edition)

4. Attach Northwind Database to Databases in Sql Express
5. Attach pubs Database to Databases in Sql Express

Notes:

• Console Application is used to simplify things, but Windows Forms or Web Forms could also be used
• You can build a library of syntax examples by using same project over and over and just commenting out what you do not want to execute in Program.cs
