LINQ query to return whether an item is found in an array?

Question

I am learning LINQ, and I am not sure how to write a query to return a boolean indicating whether an item is found in an array. I have a very simple list:

var targetProperties = new string[] { "SelectedDate", "SelectedMonth" };

I need to write a LINQ query that will return true if an item passed in is in the array, and false if it isn't. What would that query look like? Thanks for your help.

Answer 1

targetProperties.Contains("SelectedDate") ?

Answer 2

bool answer = targetProperties.Any(x => x == "SelectedDate");
