Hi, I have a string which is "ABCD1234", if I use substring to cut the string as below:

C#

string strOld = "ABCD1234"
string strNew = strOld.Substring(4, 7);

Would the output be "1234" even I do not value anymore after the value "4"?
I can't debug it at my PC as my PC has gone for repair shop. Any help would be appreciated.

Nope. I tried running the code through here http://www.tutorialspoint.com/compile_csharp_online.php[^]

I've changed the number 7 to 4 to output 1234.

C#

using System.IO;
using System;

class Program
{
    static void Main()
    {
        string strOld = "ABCD1234";
        string strNew = strOld.Substring(4, 4);
        Console.WriteLine(strNew);
    }
}
