Question

I need to add data to view model using LINQ
My view model is :

public class SearchScrapViewModel 
{ 
public WClass wClass{get; set;} 
public SClass sClass{get; set;} 
public YClass yClass { get; set; } 
} 

public class WClass 
{ 
public string title { get; set; } 
public string link { get; set; } 
} 
public class SClass 
{ 
public string title { get; set; } 
public string link { get; set; } 
} 
public class YClass 
{ 
public string title { get; set; } 
public string link { get; set; } 
}

and i need to use these 3 classes with 3 different LINQ query and then pass data to return View(SearchScrapViewModel);

var wikians = //LINQ Logic 
select new SearchScrapViewModel 
{ 
wClass.link = link.Attributes["href"].Value, //Error: I am not able to add to wClass 
wClass.title = link.InnerText 
}; 

and similarly to other classes

and then pass to return View(SearchScrapViewModel); so that i can access all the 3 classes in View of this controller

How to do that?

You forgot to create an instance of your WClass:

select new SearchScrapViewModel {
    wClass = new WClass { 
        link = link.Attributes["href"].Value,
        title = link.InnerText 
    }
}; 

Alternatively, you could make WClass (and SClass and YClass) a struct instead of a class, then you don’t need to instantiate it. In that case, however, you should probably make the struct immutable.
