vs2005中的强类型dataset
vs2005中的新的dataset,与2003中有着不同，创建 Typed dataset后，系统自动加入了TableAdpter,根据提供的这个TableAdapter,就可以很方便的写出DataAccess Layer Code,DataAccess Layer的编写更加简便，以下是一个简单的示例。
using System;using System.Collections.Generic;using System.Text;namespace DatasetTest
{
public class TestDataAccess:IDisposable 
{ private dsNorthwindTableAdapters.CustomersTableAdapter dsc = new DatasetTest.dsNorthwindTableAdapters.CustomersTableAdapter(); public dsNorthwind.CustomersRow RetiereCustomersRow(string customersid) { //dsNorthwindTableAdapters.CustomersTableAdapter ct = new DatasetTest.dsNorthwindTableAdapters.CustomersTableAdapter(); dsNorthwind.CustomersRow dcr = dsc.GetDataByCustomerID(customersid)[0]; return dcr; 
} public dsNorthwind.CustomersDataTable RetiereCustmoers() { //dsNorthwindTableAdapters.CustomersTableAdapter ct = new DatasetTest.dsNorthwindTableAdapters.CustomersTableAdapter(); return dsc.GetData(); } public void UpdateCustomers(dsNorthwind.CustomersRow CustomersRow) { dsc.Update(CustomersRow); }
IDisposable 成员 }
}
