You can achieve this using WMI Classes. But the prerequisite is

• the application and must be running

below the sample code to do this

 string queryString = 
                "SELECT Name, ProcessId, Caption, ExecutablePath" + 
                "  FROM Win32_Process";

            SelectQuery query = new SelectQuery(queryString);
            ManagementScope scope = new System.Management.ManagementScope(@"\\.\root\CIMV2");

            ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
            ManagementObjectCollection processes = searcher.Get();


            foreach(ManagementObject mObj in processes)
            {
                               var name = mObj ["Name"].ToString();
                                var ProcessId = Convert.ToInt32(mObj ["ProcessId"]);
                                var Caption = mObj ["Caption"].ToString();
                                var Path = mObj ["ExecutablePath"].ToString();
            }
