To retrieve a list of running processes use: System.Diagnostics.Process.GetProcesses() which returns an array av Process objects.

with this System.Diagnostics.Process.GetProcesses() i get all the running processes. but i want the process name who has taken the handle of particular text file. As in input parameter i will give textfile name and want the process who has taken the handle of the textfile.

Do you have the name of the text file and you want to retrieve the process which has the handle to that file? Could you please elaborate more?

This is inposible to do it completly in C#. You must not be afrait to use a lot of PInvoke I hope this a few articles help you: (I think the last link will be best) http://social.msdn.microsoft.com/Forums/en-US/csharpgeneral/thread/9e2044c5-ae5d-4552-a335-01cc567dfc58[^] http://stackoverflow.com/questions/242882/how-can-i-unlock-a-file-that-is-locked-by-a-process-in-net[^] http://www.codeguru.com/Cpp/W-P/files/fileio/article.php/c1287/#more[^] http://www.vbforums.com/showthread.php?t=501992[^]

Hi Check this out it might help you..i hav'nt tried it but looks like this is what you are looking for.. fpound this solution while going thrw some blog :) posted by :-Gennady Zabrodsky It is very complex way to invoke Win32 from C#. You should use tool Handle.exe from http://technet.microsoft.com/en-us/sysinternals/bb896655.aspx After that your C# code have to be the following: string fileName = @"c:\aaa.doc";//Path to locked file Process tool = new Process(); tool.StartInfo.FileName = "handle.exe"; tool.StartInfo.Arguments = fileName; tool.StartInfo.UseShellExecute = false; tool.StartInfo.RedirectStandardOutput = true; tool.Start(); tool.WaitForExit(); string outputTool = tool.StandardOutput.ReadToEnd(); string matchPattern = @"(?<=\s+pid:\s+)\b(\d+)\b(?=\s+)"; foreach(Match match in Regex.Matches(outputTool, matchPattern)) { Process.GetProcessById(int.Parse(match.Value)).Kill(); }
