Try this: using System; using System.Diagnostics; class Program { static void Main() { Process[] procs = Process.GetProcesses(); long maxMemory = 0L; string name = null; foreach(Process p in procs) { if(p.WorkingSet64 > maxMemory) { maxMemory = p.WorkingSet64; name = p.ProcessName; } } Console.WriteLine(The process using the most memory is {0} using {1} bytes name maxMemory); Console.ReadKey(); } }

This should work. var processList = Process.GetProcesses() .Where(p => p.ProcessName.Contains(txtSearch.text)) .FirstOrDefault(); if (processList != null) { Console.Write(processList.MainModule.FileName); } Console.Read();

A bit more about the system and idle processes. According to a book I have on Windows Internals they are not user-mode processes and don't have an exe file which is why they don't have any modules.

According to the documentation for the Process.Modules property ( http://msdn.microsoft.com/en-us/library/system.diagnostics.process.modules.aspx )  the system process and the idle process do not have modules and so you will get a Win32Exception if you try to access them. There are also some other exceptions that may arise. To avoid one of these bringing down the application you'll need to catch the exception and inform the user about it: Process[] procs = Process.GetProcessesByName(txtSearch.Text); if(procs.Length > 0) { MessageBox.Show(The process ' + txtSearch.Text + ' was found); try { txtPath.Text = procs[0].MainModule.FileName; } catch(Exception ex) { MessageBox.Show(ex.Message); } }

baisically yes but i'm getting an exaption : Unable to enumerate the process modules

Do you mean something like this: Process[] procs = Process.GetProcessesByName(txtSearch.Text); if(procs.Length > 0) { MessageBox.Show(The process ' + txtSearch.Text + ' was found); txtPath.Text = procs[0].MainModule.FileName; }

I woult try to explain it better say i search for the process System. my function return a message that the process was found. I would like that after showing that msg the path of this specific process will be shown on a text box

You could probably use something like this. static void Main(string[] args) { string name = GetProcess(); txtProcessName.Text = name; } private static string GetProcess() { var processList = Process.GetProcesses() .OrderByDescending(p => p.WorkingSet64) .First(); return processList.MainModule.FileName; }

Another example would be. class Program { static void Main(string[] args) { var processList = Process.GetProcesses() .OrderByDescending(p => p. WorkingSet64 ) .First(); Console.WriteLine({0} {1} processList.ProcessName processList.WorkingSet64); Console.Read(); } } I would like to note that this is not actually comparing it is just printing the information of the process that is using the most memory at the time.
