Implicit downcast from 'System.IO.Stream' to 'System.IO.MemoryStream'

Question

function SerializeObject(pObject : Object)
{
   var XmlizedString : String  = null;
   var memoryStream : MemoryStream  = new MemoryStream();
   var xs : XmlSerializer = new XmlSerializer(typeof(XmlData));
   var xmlTextWriter : XmlTextWriter  = new XmlTextWriter(memoryStream, Encoding.UTF8);
   xs.Serialize(xmlTextWriter, pObject);
   memoryStream = xmlTextWriter.BaseStream;
   XmlizedString = UTF8ByteArrayToString(memoryStream.ToArray());
   return XmlizedString;
}

The problem lies in the line:

memoryStream = xmlTextWriter.BaseStream;

I am aware that xmlTextWriter.BaseStream is of the type stream, but how would I go about typecasting it?

thanks for any help in advanced!

Are you sure that's javascript? Also, if those classes are anything like I'd expect, why do you need to extract the `BaseStream` from the `xmlTextWriter`? Isn't it just the same stream that was already referenced by the `memoryStream` variable, and passed into the `XmlTestWriter` constructor? — Damien_The_Unbeliever, Nov 13 '12 at 07:52

You can use as for reference types.

Try:

memoryStream = xmlTextWriter.BaseStream as MemoryStream;
