Why linq?

C#

String first = (From item In ComboBox1.Items).FirstOrDefault;
String last = (From item In ComboBox1.Items).LastOrDefault;

Isn't the normal way easier?!

C#

String first = ComboBox1.Items[0];
String last = ComboBox1.Items[ComboBox1.Items.Count-1];

Correct, my 5. I was good to show LINQ anyway.

Solution 2

Linq and ComboBox dont work well.

Try this approach.

ComboBox cb = new ComboBox();
List<object> list = cb.Items.Cast<object>().ToList();
object first = list.First();
object last = list.Last();

Good luck!

Items.Cast is not needed, but it was good to show this technique. My 5.

Why on Earth it should be LINQ? This is simply myComboBox.Items[0] and myComboBox.Items[myComboBox.Items.Count-1]…

The only reason I can see it is somebody told you to do that, but we don't have to answer such Questions; in this case that person should ask CodeProject, not you. This is how it works.
