If your objective is simply to dump the memory stream to a physical file (e.g. to look at the contents) - it can be done in one move:

System.IO.File.WriteAllBytes(@"C:\\filename", memoryStream.ToArray());

No need to set the stream position first either, since the .ToArray() operation explicitly ignores that, as per @BaconBits comment below https://docs.microsoft.com/en-us/dotnet/api/system.io.memorystream.toarray?view=netframework-4.7.2.
