Creating Word Document from Byte Array and Viceversa

//Reading a Word Document and Converting to Byte Array (Can Be Saved to DB)
byte[] myByteArray = System.IO.File.ReadAllBytes(Request.PhysicalApplicationPath + "\\document\\Test.doc");

//Converting the Byte Array to a WordDocument Again (Retrieved from DB)
FileStream fs = new FileStream(Request.PhysicalApplicationPath + "\\document\\Test2.doc", FileMode.Create, FileAccess.ReadWrite);
BinaryWriter bw = new BinaryWriter(fs);
bw.Write(myByteArray);
bw.Close();
