找不到 XDocument 和 XElement

Question

I'm trying to parse an xml and I want to get access to either XDocument or XElement . Those 2 classes currently don't exist.

I'm using Visual Studio. Am I suppose to add a reference? I currently have System.Xml.linq selected but I still can't access the 2 classes above...

Answer 1

You need the System.Xml.XDocument.dll for XDocument and XElement .

See the docs :

If you don't have that dll on your system, you could install the System.Xml.XDocument NuGet package.

Install-Package System.Xml.XDocument -Version 4.3.0
