Question

Anyone know how to select a certain amount of items in a List to bind to a DataSource? Basically I’m getting back 10 items (which I don’t have control over) and I only need to show 5. Originally I was thinking of using a loop and adding 5 items to a new list but that seems like a lot of code. Is there an expression that I can use to select the first 5?

//Returns a List<DataItem>
MyDataListControl.DataSource = Helper.GetDataItems(); //<= Possible expression?

You may take a look at the Skip and Take LINQ extension methods. So in your case if you wanted to take only the first 5 elements of some IEnumerable<T>:

MyDataListControl.DataSource = Helper.GetDataItems().Take(5).ToList();
