Cast IList to List

I am trying to cast IList type to List type but I am getting error every time.

List<SubProduct> subProducts= Model.subproduct;

Model.subproduct returns IList<SubProduct>.

Solution 1:

Try

List<SubProduct> subProducts = new List<SubProduct>(Model.subproduct);

or

List<SubProduct> subProducts = Model.subproducts as List<SubProduct>;

Solution 2:

How about this:

List<SubProduct> subProducts = Model.subproduct.ToList();

Solution 3:

In my case I had to do this, because none of the suggested solutions were available:

List<SubProduct> subProducts = Model.subproduct.Cast<SubProduct>().ToList();

Solution 4:

List<SubProduct> subProducts= (List<SubProduct>)Model.subproduct;

The implicit conversion failes because List<> implements IList, not viceversa. So you can say IList<T> foo = new List<T>(), but not List<T> foo = (some IList-returning method or property).
