string Message = Console.ReadLine(); if (Message != ) { if (Message == add) Add(); if (Message == deduct) Deduct(); } It's work now thanx a lot

this  ConsoleApplication1 add just has to work. a suggest putting a breakpoint or writing the content of that array to the console to check what is actually inside. foreach (var arg in args) { Console.WriteLine(arg); }

Michal Habalcik · Answer

static void Main(string[] args) { if (args.Length == 0) { foreach (var arg in args) { if (arg == add) Add(); if (arg == deduct) Deduct(); } } Console.ReadLine(); } public static int Add() { int a; int b; int c; Console.WriteLine(Enter value of 'a':); a = Convert.ToInt32(Console.ReadLine()); Console.WriteLine(Enter value of 'b':); b = Convert.ToInt32(Console.ReadLine()); c = a + b; Console.WriteLine(a + b = {0} c); Console.ReadLine(); Console.ReadLine(); return c; } public static int Deduct() { int a; int b; int c; Console.WriteLine(Enter value of 'a':); a = Convert.ToInt32(Console.ReadLine()); Console.WriteLine(Enter value of 'b':); b = Convert.ToInt32(Console.ReadLine()); c = a - b; Console.WriteLine(a - b = {0} c); Console.ReadLine(); Console.ReadLine(); return c; }

Hello It's not working

Michal Habalcik · Answer

Hi not sure I understand as everything is described above. If you add the above code in your Main method you can call the Add function from command prompt by typing: consoleapplication1 add

Helo Michal how can we take input then

Michal Habalcik · Answer

Hi the main method's arguments represent command prompt arguments static void Main(string[] args) so you need to handle input in your main method something like this: foreach (var arg in args) { if (arg == add) call your add method here; } afterwards you can call it from command prompt like consoleapplication1 add More info on MSDN
