The type arguments for method 'System.Linq.Enumerable.Where(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly.

Hi

I get the error message above on the following piece of code:

SPView _view = Web.Lists["Client Contact"].Views["All Items"];
SPListItemCollection listItems = Web.Lists["Companies"].GetItems(_view);
string CompanyChoice = default(string);
string comp = "Company";

IEnumerable<string> FilteredLists = listItems.OfType<string>().Where(listItems[comp].ToString().Equals(CompanyChoice));

I get the error on the last line, I'm not enitrely sure why?

Can anyone see where I am going wrong?

 many thanks

If you new to linq you should watch the videos at http://www.asp.net/learn/linq-videos/.

You have to pass a function that takes a string and returns true or false in your case. Something like this:

listItems.OfType<string>().Where(li => li.ToString().Equals(CompanyChoice));
