I am trying to trace IP-Address who is deleting files from my share folders. I have write a code to get information when trying to do something in my share folder but, I can't get the IP from where the delete event's is occurred.

Here is my Code:

private void Form1_Load(object sender, EventArgs e)
        {
            FileSystemWatcher fsw = new FileSystemWatcher();
            fsw.Path = @"E:\Mahbub IT\";
            fsw.EnableRaisingEvents = true;
            fsw.Filter = "*.*";
            fsw.IncludeSubdirectories = true;
            fsw.Created += new FileSystemEventHandler(file_handler_function);
            fsw.Changed += new FileSystemEventHandler(file_handler_function);
            fsw.Deleted += new FileSystemEventHandler(file_handler_function);
            fsw.Renamed += new RenamedEventHandler(file_rename_handler_function);
        }

private void file_handler_function(object sender, FileSystemEventArgs e)
        {
            if (e.ChangeType == WatcherChangeTypes.Created)
            {
                MessageBox.Show("New file created : " + e.FullPath);
            }
            else if (e.ChangeType == WatcherChangeTypes.Deleted)
            {
                MessageBox.Show("File is deleted : " + e.FullPath);
                //MessageBox.Show(Request.UserHostAddress);
            }
            else if (e.ChangeType == WatcherChangeTypes.Changed)
            {
                MessageBox.Show("File modified : " + e.FullPath);
            }
        }

This is working good but, I want to add IP-Address in MessageBox.Show(Client::IP).

Thank you advance.
