C#: How to find if process was invoked by current application?

Question

Is there any way to determine if process was invoked by current application? I'm opening and Excel Interop process, handling files, etc, and after that I want to close only this Excel process which I've invoked.

Something like this:

Process[] pProcess = System.Diagnostics.Process.GetProcessesByName("Excel");
                foreach (var process in pProcess)
                {
                    if (process.Parent == "MyApp.exe") process.Kill();
                }

You could keep a reference to the Interop objects and close them when you wish. — Ryan Amies, Jun 08 '12 at 13:10
Take a look at [this][1] post. It's working and will do. [1]: http://stackoverflow.com/questions/394816/how-to-get-parent-process-in-net-in-managed-way — t3hn00b, Jun 08 '12 at 13:12
@t3hn00b for future reference, use [ text-to-display ] ( link ) — default, Jun 08 '12 at 13:29
@Default well it was intended as an answer but there's some sort of "generic answer" protection system and my answer became a comment — t3hn00b, Jun 08 '12 at 13:55
@t3hn00b did not know that. But now I do (and knowing is half the battle!) — default, Jun 08 '12 at 15:51

Usage:

Console.WriteLine("ParentPid: " + Process.GetProcessById(6972).Parent().Id);

Code:

public static class ProcessExtensions {
private static string FindIndexedProcessName(int pid) {
    var processName = Process.GetProcessById(pid).ProcessName;
    var processesByName = Process.GetProcessesByName(processName);
    string processIndexdName = null;

    for (var index = 0; index < processesByName.Length; index++) {
        processIndexdName = index == 0 ? processName : processName + "#" + index;
        var processId = new PerformanceCounter("Process", "ID Process", processIndexdName);
        if ((int) processId.NextValue() == pid) {
            return processIndexdName;
        }
    }

    return processIndexdName;
}

private static Process FindPidFromIndexedProcessName(string indexedProcessName) {
    var parentId = new PerformanceCounter("Process", "Creating Process ID", indexedProcessName);
    return Process.GetProcessById((int) parentId.NextValue());
}

public static Process Parent(this Process process) {
    return FindPidFromIndexedProcessName(FindIndexedProcessName(process.Id));
}
}

you can hold a reference to the Excel-Interop-Process and kill it if you've done what you want to...

Look at this example:

static void Main(string[] args)
    {
        var excelApp = new Microsoft.Office.Interop.Excel.Application();
        var workbook = excelApp.Workbooks.Open(Filename: @"someexcelworkbook.xls");
        workbook.Activate();
        excelApp.Visible = true;
        excelApp.Quit();
    }

Hope this is helpfull.. ;-)
