My linq query converted to IList. How to query?

Question

_{Tuesday, February 3, 2015 4:45 AM}

Hi I have a ling query which I need to filter  several time based on a name value.

Resharper warns that of "multiple enumeration of ienumerable". This is suppose to be inefficient.

It converted it to this:

var query= myQueryS as IList ?? myQuery.ToList();

Question is what is "query" now and how do you actually get the results you need from it?

Thanks.

Chances are whatever myQueryS is can be converted to IList which is non-generic, and the methods like Select work on the generic IList<T>

Just use

var query= myQuery.ToList();

that will ensure query is List<T>

Hover over "var" in Visual Studio and the pop-up will tell you what query is.  If myQueryS is IEnumerable<T> then query will be List<T>.  You get results from it the same way you do IEnumerable.  It would help if you posted some of the relevant code.

When I hover over it I see the list of results, lots of rows.

But it does not allow me to do a .select on it?

Do you have

using System.Linq;

at the top of your code file?
