Here is the code to deserialize the object reading the file: BinaryFormatter bf = new BinaryFormatter(); bool IsFromArchive = true; string temporalfilename = "yourfile.dat"; string m_data =""; string mp_lasterror = ""; if (IsFromArchive) { if (File.Exists(Application.StartupPath + @"\Temp\" + temporalfilename)) { FileStream fstream = new FileStream(Application.StartupPath + @"\Temp\" + temporalfilename, FileMode.Open, FileAccess.Read); try { m_data = (string) bf.Deserialize(fstream); } catch (Exception ex) { mp_lasterror = ex.Message; } finally { //todo } fstream.Close(); } else MessageBox.Show("The file" + temporalfilename + " was not found in the path!"); } Regards

You must implement a deserialization process. If you know that the serialized object (binary) is or can be transformed into an string (ASCII code), only apply a cast to the deserialized object and gotcha!. the following code deserialize an object. The folowing code ONLY transform the binary object from an array of bytes (bytes[]).- /// /// Deserialize an object from an array of bytes. /// /// The array of bytes with the object to deserialize /// The object deserialized public static object BinaryTo(byte[] SerializedImage) { IFormatter formatter; MemoryStream memStream = null; Object objectFromBinary = null; //Cursor saveCursor = Cursor.Current; //try //{ //Cursor.Current = Cursors.WaitCursor; try { memStream = new MemoryStream(SerializedImage); formatter = new BinaryFormatter(); objectFromBinary = formatter.Deserialize(memStream); } catch (Exception exception) { mp_lasterror = exception.Message; } finally { if (memStream != null) memStream.Close(); } //} //finally //{ // Cursor.Current = saveCursor; //} return objectFromBinary; } Regards CFQüeb
