SqlDataAdapter.Update()方法与SqlCommandBuilder(转)

strcon1 = "Data Source=.;Initial Catalog=Northwind;Integrated Security=True"; using (SqlConnection conn = new SqlConnection(strcon1)) { conn.Open(); string strsql = "select * from employees"; SqlCommand cmd = new SqlCommand(strsql, conn); ad = new SqlDataAdapter(); ad.SelectCommand = cmd; dt = new DataTable("employees"); ad.Fill(dt); ds = new DataSet(); ds.Tables.Add(dt); this.dataGridView1.DataSource = ds.Tables[employees];

 

增加一行记录：
//新增加一行

                DataRow newRow = dt.NewRow();
                newRow["EmployeeID"] = 11;
                newRow["LastName"] = "Bill";
                newRow["FirstName"] = "Gata";
                dt.Rows.Add(newRow);

 

更新：用Update更新时提示要有SqlDataAdapter的InsertCommand ，这里我们可以用SqlCommandBuilder自动为我们生成

                //使用SqlCommandBuilder自动生成带有Insert语句的InsertCommand
                SqlCommandBuilder cb = new SqlCommandBuilder(ad);
                ad.InsertCommand = cb.GetInsertCommand();
                //将DataSet中的数据更新到数据库中
                ad.Update(ds, "employees");

 

}

 

在CSDN博客上看到的，感觉不错，就转过来了。
