Use LINQ where list of items contains any component in a list of components

Question

Using LINQ, how can I find a list of items where it\'s list of components contains a component from another list of components?

Structure:

class Item
{
          


        

Answer 1

It because Any expects boolean value, but you return string: x.Name.ToString.

You can check intersection of two sequences in you case:

items.Where(x => x.Components.Intersect(components).Any())

Intersect will return non-empty sequence, if both item.Components and components contain same elements. Then Any without parameters will return true, if the sequence is non-empty.
