list泛型自定义排序示例

　　static void Main(string[] args)

　　{

　　Employee employee = new Employee();

　　//设置初始值

　　List<Employee> employeeList = new List<Employee>();

　　employeeList.Add(new Employee() { EmpId = "001", EmpName = "Tony" });

　　employeeList.Add(new Employee() { EmpId = "002", EmpName = "Mack" });

　　employeeList.Add(new Employee() { EmpId = "003", EmpName = "Jon" });

　　employeeList.Add(new Employee() { EmpId = "004", EmpName = "Dawei" });

　　employeeList.Add(new Employee() { EmpId = "005", EmpName = "Jack" });

　　employeeList.Add(new Employee() { EmpId = "006", EmpName = "Abby" });

　　employeeList.Add(new Employee() { EmpId = "007", EmpName = "Carrie" });

　　//指定置前排序元素

　　List<Employee> toSortList = new List<Employee>();

　　toSortList.Add(new Employee() { EmpId = "003", EmpName = "Jon" });

　　toSortList.Add(new Employee() { EmpId = "005", EmpName = "Jack" });

　　toSortList.Add(new Employee() { EmpId = "007", EmpName = "Carrie" });

　　//自定义 排序委托

　　employeeList.Sort((Employee x, Employee y) => (toSortList.Count(e => e.EmpId == y.EmpId) - toSortList.Count(e => e.EmpId == x.EmpId)));
