Solution 1

Try moving to the beginning of the MemoryStream before trying to read it:

C#

ms.Seek(0L, SeekOrigin.Begin);
ms.Read(bytes, 0, (int)ms.Length);
file.Write(bytes, 0, bytes.Length);

Alternatively, use the ToArray method:

C#

byte[] bytes = ms.ToArray();
file.Write(bytes, 0, bytes.Length);

Or use the CopyTo method:

C#

ms.CopyTo(file);

Or
ms.Position = 0;
