Func<T>委托实现员工薪水冒泡排序

    /*1、首先创建一个冒泡排序类用于实现冒泡排序方法*/

 /// <summary>
    /// 冒泡排序类
    /// </summary>
    public class BubbleSorter {
        /// <summary>
        /// 定义静态排序泛型类
        /// </summary>
        /// <typeparam name="T"></typeparam>
        /// <param name="sortArray"></param>
        /// <param name="compare">带2个参数，返回bool型的排序方法</param>
        public static  void  Sort<T>(IList<T> sortArray , Func<T,T,bool>compare){
            for ( int i = 0; i < sortArray.Count-1 ; i++ ) {
                if ( compare ( sortArray[i], sortArray[i + 1] ) ) {
                    T temp = sortArray[i];
                    sortArray[i] = sortArray[i + 1];
                    sortArray[i + 1] = temp;
                }
            }
        }
    }

  /*2、再创建一个员工类，定义员工姓名和薪水属性，构造函数，重写ToString()以及供Func<T>使用的方法*/

 /// <summary>
    /// 员工类
    /// </summary>
    public class Employee {
        public Employee ( string name, decimal salary ) { this.Name = name; this.Salary = salary; }
        public string Name { get; set; }
        public decimal Salary { get; set; }
        /// <summary>
        /// 重写ToString()便于显示员工信息
        /// </summary>
        /// <returns></returns>
        public override string ToString ( ) {
            return string.Format("Name: {0}  Salary:{1}",Name ,Salary );
        }
        /// <summary>
        /// 排序方法（必须有，且为带2个参数，返回类型为bool型），供委托使用
        /// </summary>
        /// <param name="emp1"></param>
        /// <param name="emp2"></param>
        /// <returns></returns>
        public static bool CompareSalary (Employee emp1,Employee emp2 ) {
            return emp1.Salary < emp2.Salary;
        }
    }

    /*3、测试*/

 class Program {
        /// <summary>
        /// 客户端测试
        /// </summary>
        /// <param name="args"></param>
        static void Main ( string[ ] args ) {
            Employee[ ] employees = {
                                        new Employee("A",2000), 
                                        new Employee("B",4000),
                                        new Employee("C",3000),
                                        new Employee("D",2000),
                                        new Employee("E",1000)
                                    };
            BubbleSorter.Sort ( employees, Employee.CompareSalary );
            foreach ( var item in employees ) {
                Console.WriteLine ( item.ToString ( ) );
            }
            Console.ReadKey ( );
        }
    }
