如何将var转换为List c＃

Question

I would like to convert var to list value . I am getting 'myobj' var value. Now how can i convert to CandidateResume list ?.

 JavaScriptSerializer jsSerializer = new JavaScriptSerializer() { MaxJsonLength = 86753090 };
 var myobj = jsSerializer.Deserialize<List<List<CandidateResume>>>(description);

My CandidateResume class like this

public class CandidateResume
        {

            public string name { get; set; }
            public string url { get; set; }
            public string summary { get; set; }
            public string role { get; set; }
            public string compensation { get; set; }
            public string education { get; set; }
            public string expertise { get; set; }
            public string years { get; set; }
            public string relocation { get; set; }
            public string resume { get; set; }
            public string resumeExtension { get; set; }
            public string resumeMimeType { get; set; }

        }

Please see this current item value in screenshot

How can i catch item value ?

     foreach (var item in myobj)
                    {
 WebScrappingCandidate webScrappingCandidate = new WebScrappingCandidate();

}

Answer 1

Deserialize<T> returns a T ( MSDN ), which means myObj is already of type: List<List<CandidateResume>> .

Remember, var is not a type, it just uses type inference to be shorthand for: "Be whatever type I'm being assigned to".

To "flatten" this list, you could just use SelectMany :

foreach (CandidateResume resume in myObj.SelectMany(i => i))
{

}

Of course, there are other methods as well, but the crux of the answer is that you already have a list of candidate resumes. No conversion required.

Answer 2

You already have a list, the Deserialize method returns a typed result:

List<List<CandidateResume>> myobj =
  jsSerializer.Deserialize<List<List<CandidateResume>>>(description);

When you loop through that, each item is a list:

foreach (List<CandidateResume> item in myobj) {
  ...
}
