"vpn123"

v => convert to ASCII * 5 = 590       = 590
p => convert to ASCII * 5 = 560 + 590 = 1150
n => convert to ASCII * 5 = 550 + 1150 = 1700
1 => convert to ASCII * 5 = 245 + 1700 = 1945
2 => convert to ASCII * 5 = 250 + 1945 = 2195
3 => convert to ASCII * 5 = 255 + 2195 = 2450

Accepted answer
str+sum.ToString() part is just to display the whole result as string.

as per your question you wanted to add the previous sum so i added the privious sum using sum=sum+newSum.
where newsum means calculated ASCII.

use this
using System;
class HelloWorld {
  static void Main() {
    Console.WriteLine("Hello World");
    var value="vpn123";
    int sum=0;
    string str=String.Empty;
     foreach(var c in value)
     {
         if(char.IsDigit(c))
         {
             sum= sum+((Convert.ToInt32(c))*5);
             str=str+sum.ToString();
         }else{
              sum=sum+(((int)c)*5);
              str=str+sum.ToString();
         }
     }
     Console.WriteLine(str);
}
}

It is actually very simple
Ascii of a char is it's Int32 form, so for digit i converted them to char then again converted back to int and for char just conveerted them to int.
Note:- inside foreach each char is char in a string.

Hi, you can use following method to convert char to integer. char.GetNumericValue() once converted you can proceed with rest of your operations. example: cast 'v' to char and follow the process with out any issue..
