Question

With this code I can copy an xml file from the internet and save it in a folder.

WebClient client = new WebClient();
client.DownloadFile("http://www.studiovincent.net/list.xml", "test.xml");

The code works fine, but I need the test.xml file (file copied into the folder) to be hidden, so that it is visible only if I turn on “show hidden file and folders”.

Answer 1

You need to set the file attributes, use File.SetAttributes for this. Though I also use File.GetAttributes first so that any existing attributes will be preserved.

string filename = "test.xml";
FileAttributes attr = File.GetAttributes(filename);

attr |= FileAttributes.Hidden;

File.SetAttributes(filename,attr);
