        {
            Console.WriteLine("Hello C# World :-)");
        }
    }

Is this how they compile C# programs?
Thanks

You can use the CSC.EXE utility to compile your C# app. You'd then run it by simply calling the EXE name.

search for sharpDevelope if you want a free IDE

Or MonoDevelop...



- ØØ -

I downloaded the "Sharp DEVELOPE"yesterday..and unzipped it..but always get an error..I could not got it work !!!!

What error are you getting?

somthing like "NTVDM CPU..illegal..)
close/ignore !!
Today I unistalled it...What compiler do you suggest me for C#?
thanks

Sharpdevelop sucks. Its a pile of rubbish. Get VS2005 beta instead, its free.

Or mono...it is freeer...:)

I still have problem in getting C# files run...
I finaly tried an other "hello world"simple program and put that file in C:root
and from the DOS window I typed "hello.cs" then it said "MSVCR70.dll file was missing"
I downloaded that file and put it in "windows/system32" folder and tried the same program again..now it says "cscompui.dll" is missing although I put that new cssompui.dll file in system32 folder...

help me please will you?
thanks

Ok, we'll present steps. This is just one, and of course there are several other processes aside from this. But still, wanna get you started. I still don't know what you have on your machine but lemme get you started with my simple steps.

First off, download the .Net Framework here. The framework itself has the C# compiler called csc.exe. Note again, this is just one option, you can have Icazza's .Net version which is the mono from here. For the sake of this reply, I'll stick on .Net from M$.

Accessing the csc.exe (from any directory of the command line prompt) will require an environment variable Path to be edited (for WinXP/Win2k, might be editing autoexec.bat if you're on 9x). Right click on My Computer and Select Properties, Advanced Tab and click Environment Variables button, find Path on System variables and click Edit... Add ;C:\WINNT\Microsoft.NET\Framework\v1.1.4322 on the Variable value. Remember if you're on WinXP, WINNT is Windows so the variable becomes ;C:\Windows\Microsoft.NET\Framework\v1.1.4322. Also note that C: drive will vary from your system drive. Please check on this.

After editing the Path variable we can test the csc.exe on our C:\root directory. Type csc.exe and will get something like

Microsoft (R) Visual C# .NET Compiler version 7.00.9466
for Microsoft (R) .NET Framework version 1.0.3705
Copyright (C) Microsoft Corporation 2001. All rights reserved.

fatal error CS2008: No inputs specified

We can then type of our code into the directory, for example

Code:

---

public class hello{
        public static int Main(){
                System.Console.WriteLine("Hello World");
                return 0;
        }
}

---

Compile it by csc hello.cs and run it by hello. I guess this covers all. Mono btw, has mcs.exe compiler if I remember correctly.

You can also specify the path, or move the compiler to the system folder.
Thanks for the crash lesson.
