The solution depends on whether you want to load the DTD or not. If you
don't want to load the DTD then you should be able to solve the problem
simply by setting
xmlDoc.XmlResolver = null;
before you call Load or LoadXml.
Otherwise you need to implement a custom XmlUrlResolver that loads the
DTD from a location you control.

Also note that once you have a MemoryStream there is no need to use a
StreamReader first to get a string, you can simply pass the MemoryStream
to the Load method of XmlDocument.
