Error at line Image.FromStream(ms, true), image from db

I am trying to read "ico" image from MS SQL DB and set the to button image. I am getting an error(Parameter is not valid) at line: using (var img = Image.FromStream(ms, true)) in code:

using (var ms = new MemoryStream(oleFieldBytes))
                    {
                        ms.Write(oleFieldBytes, 75, oleFieldBytes.Length - 75);
                        using (var img = Image.FromStream(ms, true))
                        {
                            barButtonItem.LargeGlyph = img;
                        }
                    }

When I read ico file from windows desktop, I do not get an error. Help, please
