How to Convert a Stream to MemoryStream

Question

In My code try:

data expected

Stream Content

engine.SetDocument((MemoryStream)content); //No work

Or

var a = new MemoryStream();
engine.SetDocument(content.CopyTo(a)); //Error

@AndresCarvajal `Stream` is abstract - so it must be something more specific in reality. It may or may not be a `MemoryStream`, so casting is not safe. What are you needing to do that requires a `Memorystream`? — D Stanley, Apr 19 '16 at 14:57

CopyTo is a void method so returns nothing, try the following:

var a = new MemoryStream();
content.CopyTo(a);
engine.SetDocument(a);

using (MemoryStream ms = new MemoryStream())
using (FileStream file = new FileStream("file.bin", FileMode.Open, FileAccess.Read)) 
{
   byte[] bytes = new byte[file.Length];
   file.Read(bytes, 0, (int)file.Length);
   ms.Write(bytes, 0, (int)file.Length);
}
