How to check if XElement has any child nodes?

问题

I have the following condition,

if (myXElement.FirstNode.NodeType == XmlNodeType.CDATA)

This throws an exception if there is no FirstNode in myXElement, so I have to check first if there is any.

Note that I need to check for nodes not elements.

回答1:

var hasDescendants = myElement.Nodes().Any();

回答2:

Sorry for the VB but wouldn't this work

    If myXElement.Nodes.Count > 0 AndAlso myXElement.FirstNode.NodeType = Xml.XmlNodeType.CDATA Then

    End If
