Object reference not set to an instance of an object. Trying to put XML into a List

I have to following XML code witch I like to convert into a List with keys and values:

<?xml version='1.0' encoding='UTF-8' standalone='no'?>
<root>
<command>getClient</command>
<id>10292</id>
</root>

My C# code is like this:

XElement aValues = XElement.Parse(sMessage);
List<KeyValuePair<string, object>> oValues = aValues.Element("root").Elements().Select(e => new KeyValuePair<string, object>(e.Name.ToString(), e.Value)).ToList();

sMessage is the XML string.

Now I'm getting the following error, and I can not figure out why: "Object reference not set to an instance of an object."

Can someone please help me? Thanks in advance!

Solution

  • "root" is your aValues element. So, there is no "root" elements in children of aValue, and aValues.Element("root") gives you null.

    Correct query:

     aValue.Elements()
       .Select(e => new KeyValuePair<string, object>(e.Name.LocalName, e.Value))
       .ToList();
