用委托处理排序

 using System; using System.Collections.Generic; using System.Text; namespace ConsoleApplication1 { class 冒泡排序 { //首先要了解冒泡排序,其实很简单就是索引前面的跟后面的比较,如果比后面的大2个值的位置就进行调换 static void Main() { int[] str ={ 0, 14, 3, 6, 1, 30, 10, 9, 28 }; for (int i = 0; i < str.Length; i++) { for (int j = i + 1; j < str.Length; j++) { if (str[j] < str[i]) { int index = str[i]; str[i] = str[j]; str[j] = index; } } } for (int m = 0; m < str.Length; m++) { Console.WriteLine(str[m]); } } } }

using System; using System.Collections.Generic; using System.Text; namespace ConsoleApplication1 { public delegate bool DelegateTest(object obj1, object obj2); class Class1 { static void Main() { Employee[] Employees = { new Employee("huguo",1000000), new Employee("lili",20000), new Employee("lulu",30000), new Employee("xixi",50000), new Employee("jianjian",10000), new Employee("yoyo",9000) }; //委托DelegateTest代理的方法是Greate DelegateTest MyTest = new DelegateTest(Employee.Greate); Sorter MySort = new Sorter(); //冒泡算法中第一个参数是对应Employees数组信息,第二个参数是委托 MySort.Sort(Employees, MyTest); for (int m = 0; m < Employees.Length; m++) { Console.WriteLine(Employees[m].ToString()); } } } class Employee { public string Name; public int Salary; public Employee(string Name, int Salary) { this.Name = Name; this.Salary = Salary; } //用override重写string方法 public override string ToString() { return string.Format(Name + ",{0:C},", Salary); } //定义一个方法,如果obj2传过来的 Salary大于obj1就返回true; public static bool Greate(object obj1, object obj2) { Employee Employee1 = (Employee)obj1; Employee Employee2 = (Employee)obj2; return (Employee2.Salary > Employee1.Salary) ? true : false; } } class Sorter { public void Sort(object[] ArrayObj, DelegateTest Test) { //下面就是冒泡算法啦 for (int i = 0; i < ArrayObj.Length; i++) { for (int j = i + 1; j < ArrayObj.Length; j++) { if (Test(ArrayObj[j], ArrayObj[i])) { object Temp = ArrayObj[i]; ArrayObj[i] = ArrayObj[j]; ArrayObj[j] = Temp; } } } } } }
