This file looks OK to me. I have permissions. See attached icon file (894 bytes long).

It seems this method doesn't support ico file. I tried with .bmp files, its working fine.

Are you sure this method doesn't support ico files? I haven't seen that claim anywhere until now. Sure would be helpful to know for sure.

Icon class is there.
c# Syntax (Toggle Plain Text) 
  1. System.Drawing.Icon c = new Icon(@"c:\app\mapp\p1.ico");
  2. pictureBox1.Image = c.ToBitmap();
Failure is not fatal, but failure to change might be. - John Wooden

I tried that--it did work. What I can't figure out is how to convert my Stream containing the icon (bitmap). I saved that icon to a file from the stream in order to narrow down the problem.

I don't understand why the Bitmap object initialization works from the file OK in this case, but not from my stream:
C# Syntax (Toggle Plain Text) 
  1.             MemoryStream ms = new MemoryStream(webClient.DownloadData(uriIcon));
  2.             Bitmap bmp = new Bitmap(ms); // throws exception
But, if I save the memorystream above to a file, then read it with the code you gave, it works (no exception thrown).

This failure (ParameterInvalid exception) only occurs with certain icons I test, which is why I provided the sample. How can I convert this icon directly from my stream to a bitmap without having to save it to a file first?

Thanks,
David
