Capture output of process synchronously (i.e. “when it happens”)

Question

I am trying to start a process and capture the output, have come a far way, but am not quite at the solution I\'d want.

Specifically, I am trying to reset the IIS on

Answer 1

I've had that problem and had to solve it when my logs where too long to read in a single readtoend.

This is what I've done to solve it. It's been doing Ok so far.

            myProcess.StartInfo.FileName = path;
            myProcess.StartInfo.Arguments = args;
            myProcess.StartInfo.UseShellExecute = false;
            myProcess.StartInfo.ErrorDialog = false;
            myProcess.StartInfo.CreateNoWindow = true;
            myProcess.StartInfo.RedirectStandardError = true;
            myProcess.StartInfo.RedirectStandardInput = (stdIn != null);
            myProcess.StartInfo.RedirectStandardOutput = true;
            myProcess.Start();

            int index;
            OpenLogFile(myLog);                      //LOGGGGGGGGGGGGG


            if (myProcess.StartInfo.RedirectStandardInput)
            {
                StreamWriter sw = myProcess.StandardInput;
                sw.Write(stdIn + Convert.ToChar(26));
            }

            StreamReader sr = myProcess.StandardOutput;
            /*stdOut = new ArrayLi
            */
            while (!sr.EndOfStream)
            {                                           //LOGGGGGGGGGGGGG
                Log(sr.ReadLine(), true);
            }

Here's OpenLogFile

    private void OpenLogFile(string fileName)
    {
            if (file == StreamWriter.Null)
            {
                file = new StreamWriter(fileName, true);
                file.AutoFlush = true;
            }
    }

Of course that Log is a function that does something elsewhere. But the solution to you question lies here:

        while (!sr.EndOfStream)
        {                                           //LOGGGGGGGGGGGGG
            Log(sr.ReadLine(), true);
        }

while stream reader is still reading, you can be writing it down as the log comes out.
