[Mono-list] Xml Entity Resolution

[colin at breame.net]

Hi,

I've tried your solution with both XmlTextReader and XmlValidatingReader
but I can't make it work.  The problem is that the XmlTextReader
actually requires entities to be resolved.

As a work around I've subclassed XmlTextReader to return false for
CanResolveEntity, which seems to (at least initially) do the trick.  See
below.

Thanks
C.

using System.IO;
using System.Xml;

public class NonEntityResolvingXmlTextReader : XmlTextReader {
  public NonResolvingXmlTextReader(TextReader reader) : base(reader) {
  }

  public override bool CanResolveEntity {
    get {
      return false;
    }
  }
}
