Question

This is a quick one. I have the following code:

foreach (var item in myRepeater.Items)
{
    MyViewModelItem x = new MyViewModelItem();
    MapToEntity(x, item);
    myList.Add(report);
}

void MapToEntity(object entity, Control control);

I expected this code to compile with no problems. It didn’t, however.

It resulted in a compile time error saying that the method “MapToEntity” has some invalid arguments. The compiler failed to infer the type of the RepeaterItem, it recognizes it as a plain System.Object.

Why is this happening? Am I missing something?

Ps: I fixed the code by deleting the var keyword and explicitly defining the type of the item “RepeaterItem”.

Answer 1

RepeaterItemCollection does not implement IEnumerable<RepeaterItem> just plain IEnumerable. Thus, it’s impossible for the compiler in infer the type.
