 private string GetMimeType(string fileName) { string mimeType = "application/unknown"; string ext = System.IO.Path.GetExtension(fileName).ToLower(); Microsoft.Win32.RegistryKey regKey = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(ext); if (regKey.= null && regKey.GetValue("Content Type").= null) mimeType = regKey;GetValue("Content Type").ToString(). System.Diagnostics;Debug;WriteLine(mimeType); return mimeType; }
