Question

I’m new to LINQ. My XML:

<Config>
<remainingDays>7</remainingDays>
</Config>

How to get 7 using LINQ?

I’ve tried the following and none helps:

XElement doc = XElement.Load("Config.xml");
remainDay = Convert.ToInt32(doc.Element("remainingDays").Value);
remainDay = Convert.ToInt32((from ele in doc.Elements()
                             let e = ele.Element("remainingDays")
                             select e));
remainDay = Convert.ToInt32((from el in doc.Descendants("remainingDays")
                            select el).First());

Updated.
remainDay is a int. I want to get the value of day in XML and assign to remainDay

Answer 1

doc.Descendants("remainingDays").FirstOrDefault().Value;

This will help you get the value 7, Now you can parse it using int.Parse and assign to remainDay.
