Question

Here is what is the official explanation of firstObjectCommonWithArray in Objective C:

Returns the first object contained in the receiving array that’s equal
to an object in another given array.

Original signature is – (id)firstObjectCommonWithArray:(NSArray
*)otherArray

Is there anything like this for a List in .NET?

Answer 1

There is no direct single method but you could certainly build one using linq.

var first = array1.FirstOrDefault(x => array2.Contains(x));
