How to programmatically compile a c code from a c# code using mingw32-gcc compiler

Question

I want to compile a C code from c# programmatically. I am trying but i have not found any solution yet. Here is my code.

try {
    var info = new ProcessStartInfo {
        FileName = "cmd.exe",
        Arguments = "mingw32-gcc -o a Test.c"
    };
    var process = new Process { StartInfo = info };
    bool start = process.Start();

    process.WaitForExit();
    if (start) {
        Console.WriteLine("done");
    }
} catch (Exception) {
    Console.WriteLine("Not done");
}

I am using VS2010 in windows 7 and I have installed mingw32-gcc and my environment variable for mingw32-gcc is C:\Program Files\CodeBlocks\MinGW\bin Any Help will be appreciated. Thanks in advance.

So that we understand the context: What do you intend to do with the resulting C code? — Oliver Charlesworth

+1 for finally allowing C-injection on a website. I hate SQL. — Henk Holterman

What's the error you got and what the environment variable you talk about? Or does it simply never end (which is what I expect, since you open up a command prompt). Have you tried with Filename set to the actual path of mingw32-gcc.exe, no need to call cmd.exe? Make sure to include ".exe". — Abel

Try

Process process = Process.Start(
         @"C:\Program Files\CodeBlocks\MinGW\bin\mingw32-gcc.exe", "-o a Test.c");

@YoryeNathan I wouldn't really call mingw32 something to enjoy.

@ta.speot.is Doesn't matter, he should get the credit and the thank you if the answer helped the OP.

@YoryeNathan It seems the sarcasm train was an express.

Calling the cmd.exe program is not necessary. You can directly call the mingw32-gcc.exe program with arguments.

Edit:

string szMgwGCCPath = "C:\\mingw32\\bin\\mingw32-gcc.exe"; // Example of location
string szArguments = " -c main.c -o main.exe"; // Example of arguments
ProcessStartInfo gccStartInfo = new ProcessStartInfo(szMgwGCCPath , szArguments );
gccStartInfo.WindowStyle = ProcessWindowStyle.Hidden;
Process.Start(gccStartInfo );

Regards

Directly calling mingw32-gcc.exe with arguments did not solve my problem man.Can you be specific? Thanks for replying. Regards

@ForhadHussain: can you be specific with "did not solve my problem"? Errors, locks, what? Grifos is right in that you should not call "cmd.exe".

Right @Abel i did not call cmd.exe then. But my program is now working correctly because i have edited it. Thanks you all.
