static void Main(string[] args)
{
Employee employee = new Employee();
// Set the initial value
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" });
// Specifies the presorted elements
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" });
// The custom Commissioned by sorting
employeeList.Sort((Employee x, Employee y) => (toSortList.Count(e => e.EmpId == y.EmpId) - toSortList.Count(e => e.EmpId == x.EmpId)));
}
public class Employee
{
public string EmpId
{
get;
set;
}
public string EmpName
{
get;
set;
}
}
After sorting, the elements in the original list sorted by 001,002,003 are sorted as 003,005,007,001,002,004... Place the specified number 003,005,007 at the top of List
