Question

I am executing a thread which invokes BCP out in command prompt using C# win apps.
I want to do some action if thread execution is completed i.e. BCP out is completed.
BCP out is carried on local machine.
How should i check whether the thread execution is completed or not ???
my code looks like

using(this.proc = new Process())
{
    var procStartInfo = 
    new ProcessStartInfo(cmdFileName)
        {
            UseShellExecute = false,
            RedirectStandardOutput = true,
            RedirectStandardError = true,
            WindowStyle = ProcessWindowStyle.Hidden,
            CreateNoWindow = true
        };

    this.proc.StartInfo = procStartInfo;
    if(this.proc.Start())
    {
        var thread1 = new Thread(this.GetError)  { IsBackground = true };
        var thread2 = new Thread(this.GetOutput) { IsBackground = true };
        thread1.Start();
        thread2.Start();

        // check if thread execution is completed then do some logic
    }
}

A standard trick is:

thread1.Join();
thread2.Join();

//can only get here once both threads are finished.

Update

Okay so you actually want to check if the process has exited?

Then you have the HasExited property of System.Diagnostics.Process.

Here’s a slightly dirty way:

while(!proc.HasExited){
  Thread.Sleep(1000); //wait a second
}
