try this:

Process[] open_procs = Process.GetProcessesByName("nameOfProcess");
if(open_procs.Length > 0)
foreach(var proc in open_procs)
This kills any open processes you specify.

Solution 1

protected virtual bool IsFileinUse(FileInfo file)
     FileStream stream = null;

         stream = file.Open(FileMode.Open, FileAccess.ReadWrite, FileShare.None);
     catch (IOException)
         //the file is unavailable because it is:
         //still being written to
         //or being processed by another thread
         //or does not exist (has already been processed)
         return true;
         if (stream != null)
     return false;

A read-only file will fail this regardless if it is in use or not
