How can I use Process.Start() to execute program on the server-side via web service?

Question

I created a wcf service and host in IIS. Inside it has a method to execute program on the server-side by invoking from the client. It doesn't seem to work. Nothing happens when the method is called.

System.Diagnostics.Process.Start(@"C:\MtbKill.bat");

Above is the code that doesn't work. I also tried to some process.

Process[] process = Process.GetProcessesByName("Mtb");
foreach (var item in process)
{
    try
    {
        item.Kill();
    }
    catch
    {
    }
}

It is not working too. I'm very confused that is it concerned with authorization? Because I have tried such to create folder, it doesn't have any problem.

Solution

I have searched many sources of related problems. Here is what I found Access is denied at System.Diagnostics.Process.StartWithCreateProcess(ProcessStartInfo startInfo)

Please see [ask]. In particular, what do you mean, "it doesn't work"? — John Saunders, Jan 05 '15 at 04:56
Does the identity for the AppPool for your IIS App have access to c:\ ? — , Jan 05 '15 at 05:01
I don't know how to check it. Sorry, I am newbie for this. I will try moving path to another drive. — user3386894, Jan 05 '15 at 05:41
@user3386894 Just check if [Impersonating](http://support.microsoft.com/kb/306158) the process invocation code can help you. — Siva Gopal, Jan 05 '15 at 05:48
Thank you Micky Duncan. I found this is how to identify access http://www.iis.net/learn/manage/configuring-security/application-pool-identities — user3386894, Jan 05 '15 at 06:16

To run a batch file you must run "cmd.exe" with argument "/c" and the name of the file.

System.Diagnostics.Process.Start(@"cmd.exe /c C:\MtbKill.bat");

Or you can use `UseShellExecute` on `ProcessStartInfo`. – Luaan Jan 05 '15 at 08:52

This is how i start a process:

try{
 Process.Start("osk.exe", "/C");
} catch(exception ex)
{
WriteLog("Error: Onscreen keyboard could not start.", ex);
}

this is how i kill a process:

    try
    {
      Process[] processlist = Process.GetProcesses();
      foreach (Process theprocess in processlist)
      {
        if (theprocess.ProcessName == "osk")
        {
          theprocess.Kill();
        }
      }
    }
    catch (Exception ex)
    {
      WriteLog("Error: KillKeyBoardProcess", ex);
    }

Hope it helps.
