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?

Answer 1

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