Question

What would be the shortest notation to find the first item that is of a certain type in a list of elements using LINQ and C#.

Answer 1

var first = yourCollection.OfType<YourType>().First();

Note that the First method will throw an exception if there are no elements of type YourType. If you don’t want that then you could use FirstOrDefault or Take(1) instead, depending on the behaviour you do want.
