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

Michal Habalcik · Answer

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); }

I also remove that condition, but still its not working, it not goes to the loop condition

Michal Habalcik · Answer

ah, remove this if (args.Length == 0) condition. I had updated my post and you didn't realize it.

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
