Running a C# program

[neil9999]

Hi,

I've just started C# (I've seen in several places that C++ is outdated) and have found this code:


/*
HelloWorld.cs - First C# Program
Written by - Saurabh Nandu
Compilation:
csc HelloWorld.cs
*/

namespace MasterCSharp.Samples
{
public class HelloWorld
{
public static void Main()
{
//Print Hello World
System.Console.WriteLine( "Hello World !" );
}
}
}


I've saved it as helloworld.cs . How do i run the program?

I've installed Microsoft .NET Framework SDK v1.1.

Thanks,

Neil

Haven't worked with C#, but my guess is that you need to compile the code and that it will generate an EXE that can be executed.

Thanks for replying,

How do I compile the code?

From what I'm told you'll need to get out to the command prompt. Then run sdkvars.bat to set up the environment, and then the compiler command is:

CSC helloworld.cs

so say the path of my file is c:/helloworld.cs, how do I do it, step by step in command prompt?

Thanks again for your help,

I just thought I would point out that the places that you found that said that C++ was "outdated" were incorrect. While C++ is harder to use, if you code it properly, it will be faster than C#. Many people don't care much about speed now, since computers are fast enough anyway, but if you are planning on making a game(or some other high-processing application), C/C++ is by far better; but if you are just making simple applications, C# is probably better since it is fast enough and much easier to use.

BTW, the reason to this post is I couldn't stand hearing anyone say that C++ is outdated. :D :D

Should be something like:

path-of-sdk\sdkvars.bat
csc c:\helloworld.cs
helloworld

Sorry, I can't get this to work. I have Win XP. If I go into Command Prompt and type help, it doesn't list csc as a command. Any suggestions?

Thanks for your help,

CSC isn't a Windows command or an old DOS command so Help won't know about it. What's the path of the SDK? There's usually a Bin directory or similar under it that will have a few Bat files (sdkvars.bat, etc.) and some Exe and Dll files. That's where the CSC executable should be - you may have to CD over to it under the command prompt to get started.

[neil9999]

The path is C:\Program Files\Microsoft.NET\SDK\v1.1\Bin\sdkvars.bat. So there's some file I need to run to get the CSC command recognized? Which file is this?

Thanks,

Neil

the main use of C# is for asp.net, why would you use it to script in for programs? I have heard that ms will be dropping c# in a few years from an ms employee. That might not be true but you never know, he would know better then we would.
