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#region IDisposable 成员

        public void Dispose()
        {
            //throw new Exception("The method or operation is not implemented.");
           
            
            
        }

        #endregion
    }
}
