How to hide file in C#?

File.SetAttributes("pathToFile",FileAttributes.Hidden)

The previously accepted answer:

File.SetAttributes(path, FileAttributes.Hidden);

will result in certain other attributes it may have being lost, so you should:

File.SetAttributes(path, File.GetAttributes(path) | FileAttributes.Hidden);

    FileInfo f = new FileInfo(myFileName);
    f.Attributes = FileAttributes.Hidden;
