How do I kill the process exe with a specific location C#

Question

I have a requirement of killing an exe if I find an error in the log file and restart it again. The main problem here is, I cannot just delete the exe based on the name as I have the same exe running from different folders, such as D:\A\A1.exe and D:\B\A1.exe. I only want to delete the exe from "A" folder.

I have tried to follow Dirk Vollmar's Solution (https://stackoverflow.com/a/2238316/5159431).

to this question - C# Process Killing

But, when I debug his solution, I found that hModuleSnap Variable is invalid.

As Micky suggested, I have used Simon's Answer. It does kill the exe (Thanks for that). However, I am getting an error saying "System.ComponentModel.Win32Exception: Only part of a ReadProcessMemory or WriterocessMemory request was completed".

Here is the example code.

string path1 = @"F:\Software\Application\Runner.exe";


        try
        {
            Process[] runningProcesses = Process.GetProcesses();

            foreach (Process process in runningProcesses)
            {
                // now check the modules of the process
                foreach (ProcessModule module in process.Modules)
                {
                    if (module.FileName.Equals(path1))
                    {
                        process.Kill();
                    }
                }
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.ToString());
            Console.ReadLine();
        }

_"System.ComponentModel.Win32Exception"_ - I ran into that when enumerating certain OS `ProcessModule`s. You can fix it by not enumerating `process.Modules` instead reading `process.MainModule` directly. More efficient and more importantly **no exception**. Also you shouldn't update your question with a new question - post as a _new question_ leaving your original question unchanged :) — , Jul 08 '16 at 05:21

Just use ProcessModule.FileName as per Simon's answer. Note FileName returns the full path, something that is not apparent in the post.

MSDN:

Gets the full path to the module. More...

OP:

You shouldn't require this. Whilst Dirk's answer is fine, it's rather verbose and I feel makes excessive use of native calls.

Alternatively you can use my simplified version of Simon's answer (again no native calls):

NOTE: You must run the following code elevated

string targetProcessPath = @"c:\windows\system32\notepad.exe";
string targetProcessName = "notepad";

Process[] runningProcesses = Process.GetProcesses();
foreach (Process process in runningProcesses)
{
    if (process.ProcessName == targetProcessName && 
        process.MainModule != null &&
        string.Compare(process.MainModule.FileName, targetProcessPath, StringComparison.InvariantCultureIgnoreCase)==0)
    {
        process.Kill();
    }
}

The above example doesn't loop around the child modules comparing paths since Process already has a nice MainModule property that we can examine.

Now the above example isn't that thrilling but it does allow you to nuke processes called kitty running in various parts of your computer hard drive(s). You might have a c:\a\kitty.exe and d:\b\kitty.exe

Hi @MickyD, I am getting an access denied error while running the code as a normal user. If I run as an administrator then it runs successfully. I understand the user might not have access for the system processes. I also tried to change the build platform from 32 bit to 64 bit but that hasn't helped — Ravi Vyas, Jul 11 '16 at 03:30
@RaviVyas As mentioned you must _"You must run the following code elevated"_ - in other words as an _administrator_. — , Jul 11 '16 at 04:41
@Tommix well no, there might be multiple instances of Notepad running — , Apr 25 '19 at 00:13
