C# 委托实现冒泡排序

委托实现员工根据工资升序排列

首先定义员工类

  class Employee
     {
         public string Name { get; private set; }
         public decimal Salary { get; private set; }

         public Employee(string name, decimal salary)
         {
             this.Name = name; this.Salary = salary;
         }

         public override string ToString()
         {
             return string.Format("{0},{1:C}",Name,Salary);
         }
         public static bool CompareSalary(Employee e1,Employee e2)
         {
             return e1.Salary < e2.Salary;
         }
     }

重写sort方法

  class BubbleSorter
     {
         public static void Sort<T>(IList<T> sortArray, Func<T, T, bool> comparison)
         {
             bool swapped = true;
             do
             {
                 swapped = false;
                 for (int i = ; i < sortArray.Count - ; i++)
                 {
                     if (comparison(sortArray[i + ], sortArray[i]))
                     {
                         T temp = sortArray[i];
                         sortArray[i] = sortArray[i + ];
                         sortArray[i + ] = temp;
                         swapped = true;
                     }
                 }
             } while (swapped);

         }
     }

调用 方法实现排序

 Employee[] employees =
       {
         new Employee("Bugs Bunny", ),
         new Employee("Elmer Fudd", ),
         new Employee("Daffy Duck", ),
         new Employee("Wile Coyote", 1000000.38m),
         new Employee("Foghorn Leghorn", ),
         new Employee("RoadRunner", )
       };

             BubbleSorter.Sort(employees, Employee.CompareSalary);

             foreach (var employee in employees)
             {
                 Console.WriteLine(employee);
             }
