C# : Compiling Java Code in my program

[KyleUbenk]

Hello, I am attempting to compile java code from within my program. Basically I have a file in the directory with Java source code, and I want to be able to compile it from within my program. The only solution I have found so far is running the javac process :
Process.Start("javac source.java); But this doesn't seem to work (File not found).
And i would also like to get the output after compiling to a string (Error messages etc). Any other suggestions? Help is much appreciated.


Edit : Worked out now using Process.Start("javac","Leecher.java");
Only problem is now how would i get the output of that to a string?

Try using StartInfo and RedirectStandardOutput set to true. Something like (N.B This has not been tested)

public static String compileJava (String file) {
        Process p = new Process();
            p.StartInfo.FileName = "javac.exe";
            p.StartInfo.Arguments = file;
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.RedirectStandardOutput = true;
            p.Start();
                  String output = p.StandardOutput.ReadToEnd();
                Console.WriteLine(output); 
                return output;    
        }

Just tested it. You should remove that .exe from line 3 where I wrote the javac command.
