Question

Here is method which must return processes by path to executeble file.
But when i try to call this method i have an exception Win32Exception “Access is denied”.
So how to do it right?

private static List<Process> GetProcessByFilename(string filename)
        {
            List<Process> processes = new List<Process>();

            foreach (var process in Process.GetProcesses())
            {
                if (process.MainModule.FileName == filename)
                {
                    processes.Add(process);
                }
            }
            return processes;
        }

Answer 1

You will get Win32Exception when trying to get MainModule of core system processes (see comments on MSDN). You should handle that.
