How do I use System.Net.ConnectStream?

Question

I am trying to get my head around some of my predecessors code who, helpfully, has used \'var\' to declare everything.

I have a using statement which is below:

Answer 1

ConnectStream is an internal class, you can't use it explicitly. But it doesn't matter, because you don't need to know that its actual type is ConnectStream: all you need to know is that it's a Stream (the return type declared by GetRequestStream), the actual implementation doesn't really matter.

If you want to specify the type explicitly, just write it like this:

using (Stream postStream = request.GetRequestStream())
{
    postStream.Write(byteData, 0, byteData.Length);
}

(but it has exactly the same meaning as using var)
