If I kill a System.Diagnostics.Process with .Kill(), do I also need to call .Close()?

Question

Using C# 4.0, I\'ve created a System.Diagnostics.Process that I expect to take a short amount of time to run. If for some reason the process hasn\'t exited after so

Answer 1

System.Diagnostics.Process implements IDisposable via the Component class, and the protected Dispose(bool) method calls Close(). It is generally considered good practice to dispose of disposable resources when you are done with them, as this will immediately release any resources associated with the class (not having to wait for the GC to run).

So to answer your question:

Yes, please call Close() by calling the Dispose() method directly or via the C# using construct as follows.

using(Process proc = CreateProcess())
{
    StartProcess(proc);
    if (!proc.WaitForExit(timeout))
    {
        proc.Kill();
    }
}
