XmlDocument.Load(Stream) times out on 27KB of data

Question

I have the following code to load XML

var ms = new GetXmlMemoryStreamFromSomewhere();
ms.Flush();
ms.Position = 0;

// Build the XmlDocument from the MemorySteam of (usually UTF-8) encoded bytes
xmlDocument.Load(ms);

My stream is 27011 in byte size. The last line in the above code fails with System.Net.WebException Operation timed out

The Watch for ms.Position shows 4096 which means it did not read beyond 4096 bytes.

Any pointers on this would be appreciated.

Answer 1

My XML had a DOCTYPE delcaration at the top, and XmlDocument 's Load method was trying to download the DTD of the DOCTYPE which took too long and timed out.

I set the XmlResolver property to null and now my code works fine.
