如何將對象讀入和寫入SQL Server數據庫？

Question

我的第一個表是Clinics的列：

ClinicId, ClinicName, ClinicShortName 

我的第二個表是Employees的列：

EmployeeId, EmployeeName, ClinicId, OnJob 

我也有定義爲一個視圖v_employees：

SELECT 
    Employees.EmployeeId, Employees.EmployeeName, 
    Clinics.ClinicShortName, 
    Employees.OnJob 
FROM  
    Clinics 
INNER JOIN 
    Employees ON Clinics.ClinicId = Employees.ClinicId 

和我C＃代碼是：

class Employee 
{ 
    public int EmployeeId { get; set; } 
    public string EmpolyeeName { get; set; } 
    public int ClinicId { get; set; } 
    public bool OnJob { get; set; } 
} 

class Clinic 
{ 
    public int ClinicId { get; set; } 
    public string ClinicName { get; set; } 
    public string ClinicShortName { get; set; } 
} 

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

private void InitEmployees() 
{ 
    SqlConnection con = new SqlConnection(......); 

    SqlCommand cmd = new SqlCommand("select * from v_employees", con); 
    con.Open(); 

    SqlDataReader dr = cmd.ExecuteReader(); 

    while (dr.Read()) 
    { 
     Employee employee = new Employee() 
      { 
       EmployeeId = Convert.ToInt32(dr["EmployeeId"]), 
       EmpolyeeName = dr["EmployeeName"].ToString(), 
       // how to use ClinicShortName field in this position? 
       // Because I want the data to be displayed into DataGridView control. 
       OnJob = Convert.ToBoolean(dr["OnJob"]) 
      }; 

     employeeList.Add(employee); 
    } 

    dr.Close(); 
    con.Close(); 

    dataGridView1.DataSource = employeeList; 
} 

如何將對象導入SQL Server？

我應該使用List<T>方法嗎？

您必須將ClinicShortName的字段添加到employee類中，但爲什麼不使用sqladapter？它根據返回的數據生成列。

SqlConnection con = new SqlConnection(......); 
    SqlCommand cmd = new SqlCommand("select * from v_employees", con); 
    con.Open(); 
    DataTable table = new DataTable(); 
    SqlDataAdapter adapter = new SqlDataAdapter(cmd); 

    adapter.Fill(table); 
    dr.Close(); 
    con.Close(); 
    dataGridView1.DataSource = table;
