C# – Convert XDocument to Stream


How do I convert the XML in an XDocument to a MemoryStream, without saving anything to disk?

Best Answer

In .NET 4 and later, you can Save it to a MemoryStream:

Stream stream = new MemoryStream();
// Rewind the stream ready to read from it elsewhere
stream.Position = 0;

In .NET 3.5 and earlier, you would need to create an XmlWriter based on a MemoryStream and save to that, as shown in dtb's answer.
