Listlist1 = new List { 1, 2, 3, 4 }; List list2 = new List { 2, 4 }; List difference = list1.Except(list2).ToList(); // Output: [1, 3]
public class Person { public string Name { get; set; } public int Age { get; set; } } ListThis example demonstrates how `List.Except` can be used with custom objects. In this case, we have two lists of `Person` objects, and we want to find the people in `list1` who do not exist in `list2`. The result is a new list containing two `Person` objects: Alice (age 25) and Charlie (age 35). Package Library: `NUnit.Framework` is the package library that contains the `List.Except` method.list1 = new List { new Person { Name = "Alice", Age = 25 }, new Person { Name = "Bob", Age = 30 }, new Person { Name = "Charlie", Age = 35 }, }; List list2 = new List { new Person { Name = "Bob", Age = 30 }, }; List difference = list1.Except(list2).ToList(); // Output: [Person { Name = "Alice", Age = 25 }, Person { Name = "Charlie", Age = 35 }]
