Question

This error never occurred before. Here is my code;

        private Process process = null;
    private void button5_Click(object sender, EventArgs e)
    {
        if (null != process)
        {
            process.Dispose();
        }

        process = new Process();
        process.StartInfo.FileName = "world.exe";
        process.StartInfo.Arguments = "";
        process.StartInfo.UseShellExecute = false;
        process.EnableRaisingEvents = true;
        process.StartInfo.CreateNoWindow = true;
        process.StartInfo.RedirectStandardOutput = true;

        process.OutputDataReceived += new DataReceivedEventHandler(process_OutputDataReceived);
        process.Exited += new EventHandler(process_Exited);
        process.Start();
        process.BeginOutputReadLine();
    }

    private void process_OutputDataReceived(object sender, DataReceivedEventArgs e)
    {
    }

Here is what I’m getting an error on:

            process.OutputDataReceived += new DataReceivedEventHandler(process_OutputDataReceived);

That above is fine until I wrote out;

    private void process_OutputDataReceived(object sender, DataReceivedEventArgs e)
    {
    }

Help would be appreciated. Don’t know how this can be anymore specific than it is.

Answer 1

The only thing that I can think of is that you have a namespace conflict (i.e. there are other classes in your environment that match the names of the classes being used).

Try using explicit namespace declaration:

    process.OutputDataReceived += new System.Diagnostics.DataReceivedEventHandler(process_OutputDataReceived);

    private void process_OutputDataReceived(object sender, System.Diagnostics.DataReceivedEventArgs e)
    {
    }
