    class BubbleSorter    {        static public void Sort<T>(IList<T> sortArray, Func<T, T, bool> comparison)        {            bool swapped = true;            do            {                swapped = false;                for (int i = 0; i < sortArray.Count - 1; i++)                {                    if (comparison(sortArray[i+1], sortArray[i]))                    {                        T temp = sortArray[i];                        sortArray[i] = sortArray[i + 1];                        sortArray[i + 1] = temp;                        swapped = true;                    }                }            } while (swapped);               }    }

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

    class Program    {        static void Main()        {            Employee[] employees =            {                new Employee("Bugs Bunny", 20000),                new Employee("Elmer Fudd", 10000),                new Employee("Daffy Duck", 25000),                new Employee("Wile Coyote", 1000000.38m),                new Employee("Foghorn Leghorn", 23000),                new Employee("RoadRunner", 50000)            };            BubbleSorter.Sort(employees, Employee.CompareSalary);            foreach (var employee in employees)            {                Console.WriteLine(employee);            }        }    }

看了很多委託的例子，用到了很多，還是覺得這個例子最好了。。。。哈哈哈哈
