I would like to write to the file system in a directory C: \ directory name, for the moment I have this code:
if (! System.IO.File.Exists (HttpContext.Current.Server.MapPath (filename)))
{
TXTFile = new System.IO.StreamWriter (HttpContext.Current.Server.MapPath (filename));
}
else
{
TXTFile = System.IO.File.AppendText (HttpContext.Current.Server.MapPath (filename));
}
but in this way writes on the application folder. How to fix it?
You can do:
Path.Combine(@"C:\", filename)
instead of
HttpContext.Current.Server.MapPath (filename)
Ensure your application has write access to the destination.
