The XmlReader state should be Interactive

@YaronNaveh

Recently I was parsing Xml in c# from an XmlReader to an XElement:

MemoryStream m = GetMemoryStream();
XmlReader r = XmlReader.Create(m);
XElement e = XElement.ReadFrom(r) as XElement;

The last line threw this exception:

System.InvalidOperationException
The XmlReader state should be Interactive.

In MSDN ReadState.Interactive state is described as:

The Read method has been called. Additional methods may be called on the reader.

But why should I call read? It is the XElement responsibility to do it.

The solution is pretty simple though:

MemoryStream m = GetMemoryStream();
XmlReader r = XmlReader.Create(m);
//This is how we make the XmlReader interactive
r.MoveToContent();
XElement e = XElement.ReadFrom(r) as XElement;
