當兩個列表具有不同的類型時，如何合並它們？

Question

var orderedStudents = students.OrderBy(x => x.FacultyNumber).ToList();
var orderedWorkers = workers.OrderByDescending(x => x.moneyPerHour).ToList();

這些是我要合並的兩個列表，但是由於它們具有不同的類型，所以我不知道如何合並。

Answer 1

要么從通用基類派生它們，然后使用sth like

var humanBeings = orderedStudents.Cast<Human>().Concat(orderedWorkers.Cast<Human>()).ToList();

或..將它們強制轉換為通用基類:) object

Answer 2

另一個選擇：創建一個包含通用屬性的類

class Person {
    public string Name { get; set; }
    public string Lastname { get; set; }
}

var orderedStudents = students.OrderBy(x => x.FacultyNumber).Select(x => new Person { Name = x.Name, Lastname = x.Lastname});
var orderedWorkers = workers.OrderByDescending(x => x.moneyPerHour).Select(x => new Person { Name = x.Name, Lastname = x.Lastname});
var mergedList = orderedStudents.Concat(orderedWorkers).ToList();
