I'd try using WMI rather than File.Delete. The code will be something like this: using System; using System.Management; class Test { static void Main() { ConnectionOptions options = new ConnectionOptions(); options.Username = admin; options.Password = 12345; ManagementScope scope = null; ObjectQuery query = null; ManagementObjectSearcher searcher = null; try { scope = new ManagementScope(@\192.168.60.88oot\CIMV2 options); scope.Connect(); query = new ObjectQuery(@SELECT * FROM CIM_Datafile WHERE name = 'c:\c$\text.txt'); searcher = new ManagementObjectSearcher(scope query); // EDIT forgot to include 'scope' previously } catch(Exception ex) { Console.WriteLine(ex.Message); return; } foreach(ManagementObject mo in searcher.Get()) { uint returnCode = (uint)mo.InvokeMethod(Delete null); if (returnCode == 0) Console.WriteLine(File was successfully deleted); else Console.WriteLine(Deletion failed due to return code  + returnCode); } Console.ReadKey(); } }

would say hit batch program where your Environmental code will be written at the form event before you play with the files creation or deletion

Rahul thanks for ur reply. But this a form program. I actually dont understand which job will do console.writeline method. It will just write an output to screen? Basically my username is ; admin and pass : 12345. How may I authenticate?

try this Console.WriteLine(MachineName: [{0}] machineName); Console.WriteLine(UserDomainName: [{0}] Environment.UserDomainName); Console.WriteLine(UserName: [{0}] Environment.UserName);

Rahul M · Answer

Seems like you are not authenticated... if you have credentials and then add the following line of code before delete/write Console.WriteLine(MachineName: [{0}] machineName); Console.WriteLine(UserName: [{0}] userName); Console.WriteLine(Password: [{0}] password);

When I try this code; File.Delete(@\ 192.168.60.88 \c$	est.txt); I am getting this error; Logon error unknown user name or bad password

Hemant Kumar · Answer

Hi you can delete the File Like this also File.Delete(@ \192.168.60.88\c$\test.txt );

Vulpes · Answer

I think you'll need four backslashes at the beginning: File.Delete(\ \192.168.60.88\c$\test.txt ); or use a verbatim string: File.Delete(@ \192.168.60.88\c$	est.txt );

I am using the code like this but Im getting Could not find a part of the path 'C:\ 192.168.60.88 \c$	est.txt'. error. File.Delete( \192.168.60.88\c$\test.txt );

Hi I can reach the computer but after user authentication. How can I do that in C#? \192.168.60.88\c$\test.txt

Hemant Kumar · Answer

If you can reach it through a standard unc network path then that is the easiest way. \machinename\c$\ . You have to be an admin on the machine to reach that path. This works with the System.IO objects (File Directory etc.)
