public class Student : IComparable<Student> { public int? Order { get; set; } public string Name { get; set; } public Class Class { get; set; } public int CompareTo(Student other) { if (ReferenceEquals(this, other)) return 0; //如果两个值的引用相同，那么直接返回相等。 if (ReferenceEquals(null, other)) return 1; //如果该实例是空的，但是传入的实例不是空的，那么返回1 //比较学校的序号 var compareResult = CompareInit(this.Class.School.Order, other.Class.School.Order); if (compareResult != 0) return compareResult; //比较班级的序号 compareResult = CompareInit(this.Class.Order, other.Class.Order); if (compareResult != 0) return compareResult; //比较学生的学号 compareResult = CompareInit(this.Order, other.Order); if (compareResult != 0) return compareResult; //如果以上还未区分出大小，比较学校的名称 compareResult = String.CompareOrdinal(this.Class.School.Name, other.Class.School.Name); if (compareResult != 0) return compareResult; //比较班级的名称 compareResult = String.CompareOrdinal(this.Class.Name, other.Class.Name); if (compareResult != 0) return compareResult; //比较学生的名称 return String.CompareOrdinal(this.Name, other.Name); }
实现该方法后，就可以对List<Student> 使用Sort方法了，我们来试试看。
using System; using System.Collections.Generic; namespace Sort { class Program { static void Main(string[] args) { var students = InitData(); students.Sort(); //此处执行了Sort方法 Console.WriteLine("Name-Order"); foreach (var student in students) { Console.WriteLine($"学校:{student.Class.School.Name}-{student.Class.School.Order}>>班级:{student.Class.Name}-{student.Class.Order}>>学生:{student.Name}-{student.Order}"); } Console.ReadLine(); } static List<Student> InitData() //创建数据 { var school1 = new School() { Order = 1, Name = "A", }; var school2 = new School { Name = "B", Order = 0 }; var class1 = new Class { Order = 1, Name = "1", School = school1, }; var class2 = new Class { Order = 2, Name = "2", School = school1, }; var class3 = new Class { Order = 1, Name = "1", School = school2, }; var student1 = new Student { Order = 1, Name = "1", Class = class1, }; var student2 = new Student { Order = 2, Name = "2", Class = class1, }; var student3 = new Student { Order = 3, Name = "3", Class = class1, }; var student4 = new Student { Order = 1, Name = "1", Class = class2, }; var student5 = new Student { Order = 1, Name = "1", Class = class3, }; return new List<Student> { student5, student3, student4, student2, student1 }; } } }
执行效果如下：
可以看到，学校B虽然是以B开头，但是因为期Order为0比1更靠前，所以以Order为准，学校B排到了最前面。
好几天没写了，写博客对我我而言，意义无非在于加深印象同时把我所掌握的东西分享给大家，这个方法是今天同事教我的，可能对园子里大神来说这比较基础，但是相信如果掌握这个方法，对以后也许中复杂排序会有比较有用，希望对大家也能有所帮助。
