Question

I load a list of a database table via Linq in the page load of my site.

Now I must cache the list, because I will use them in a WebMethod again. (I can’t load them new, because it can be changes in there).

How to cache a List<> and get it back in a WebMethod?

Answer 1

I would say the Session would be your best bet.

Example

Storing:

var list = new List<int>() { 1, 2, 3, 4, 5 };
Session["ListOfIntegers"] = list;

Retrieving:

var list = (List<int>)Session["ListOfIntegers"];
