复制代码 代码如下:

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 = \"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)));
}
