int[] numbers = { 5, 10, 15, 20, 25 }; PredicateIn this example, the `isEven` and `isGreaterThan10` predicates are combined using the `&&` operator to create a new predicate `combined`. The `Array.FindAll` method is then used to find all elements in the `numbers` array that satisfy the conditions specified in the `combined` predicate. The Predicate class is included in the `System` namespace in C# and does not require any additional package or library.isEven = n => n % 2 == 0; Predicate isGreaterThan10 = n => n > 10; Predicate combined = isEven && isGreaterThan10; int[] filteredNumbers = Array.FindAll(numbers, combined);
