在vs.net bate 2中的ado.net简单编程（傻瓜版）
这篇文章只适合初学者，如果你是大虾，这篇文章就是浪费你的时间。首先，文件->兴建->项目。项目类型：C#，ASP。NET应用程序。
在工具箱中拖一个sqldataadapter到webform窗口中。
向导先点下一步，新建连接，在连接标签下，选取一个可用的服务器和可用的sqlserver数据库，确定。
然后配置查询生成器（太简单就不说了）。完成。
在webform中点击sqldataadapter1在属性栏的下面点生成数据集。单选框用新建，确定。
至此，和数据库的连接工作基本搞定了，让我们来操作它吧。
拖一个datagrid到webform 窗口。属性生成器中选好数据源（我们只有一个dataset)也就这样了。
然后我们来看看代码。
切换到代码窗口，添加黄色的代码：
using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;namespace WebApplication1
{
/// <summary>
/// Summary description for WebForm1.
/// </summary>
public class WebForm1 : System.Web.UI.Page
{
protected System.Data.SqlClient.SqlDataAdapter sqlDataAdapter1;
protected System.Data.SqlClient.SqlCommand sqlSelectCommand1;
protected System.Data.SqlClient.SqlCommand sqlInsertCommand1;
protected System.Data.SqlClient.SqlConnection sqlConnection1;
protected System.Web.UI.WebControls.DataGrid DataGrid1;
protected System.Web.UI.WebControls.Button Button1;
protected System.Data.SqlClient.SqlDataAdapter sqlDataAdapter2;
protected System.Data.SqlClient.SqlCommand sqlSelectCommand2;
protected System.Data.SqlClient.SqlCommand sqlInsertCommand2;
protected System.Data.SqlClient.SqlCommand sqlUpdateCommand1;
protected System.Data.SqlClient.SqlCommand sqlDeleteCommand1;
protected System.Data.SqlClient.SqlConnection sqlConnection2;
protected System.Web.UI.WebControls.DataGrid DataGrid2;
protected WebApplication1.DataSet1 dataSet11;
public WebForm1()
{
Page.Init += new System.EventHandler(Page_Init);
}private void Page_Load(object sender, System.EventArgs e)
{
// Put user code to initialize the page here
}private void Page_Init(object sender, EventArgs e)
{
//
// CODEGEN: This call is required by the ASP.NET Web Form Designer.
//
InitializeComponent();
//填充数据集sqlDataAdapter1.Fill (dataSet11);
//绑定
DataGrid1.DataBind ();
} #region Web Form Designer generated code
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
#endregion}
生成程序，如果正常的话你应该可以在datagrid看到你的数据了。
如果你对操作的数据有更高的要求的话（前提是会sql语句），你可以点饥前面绿色代码前的小加号，修改下面的兰色代码。
private void InitializeComponent()
{
this.sqlConnection1 = new System.Data.SqlClient.SqlConnection();
this.dataSet11 = new WebApplication1.DataSet1();
this.sqlInsertCommand1 = new System.Data.SqlClient.SqlCommand();
this.sqlSelectCommand1 = new System.Data.SqlClient.SqlCommand();
this.sqlDataAdapter1 = new System.Data.SqlClient.SqlDataAdapter();
this.sqlDataAdapter2 = new System.Data.SqlClient.SqlDataAdapter();
this.sqlSelectCommand2 = new System.Data.SqlClient.SqlCommand();
this.sqlInsertCommand2 = new System.Data.SqlClient.SqlCommand();
this.sqlUpdateCommand1 = new System.Data.SqlClient.SqlCommand();
this.sqlDeleteCommand1 = new System.Data.SqlClient.SqlCommand();
this.sqlConnection2 = new System.Data.SqlClient.SqlConnection();
((System.ComponentModel.ISupportInitialize)(this.dataSet11)).BeginInit();
this.Button1.Click += new System.EventHandler(this.Button1_Click);
//
// sqlConnection1
//
this.sqlConnection1.ConnectionString = "data source=(local);initial catalog=xr;integrated security=SSPI;persist security " +
"info=False;workstation id=XURUI;packet size=4096";
//
// dataSet11
//
this.dataSet11.DataSetName = "DataSet1";
this.dataSet11.Locale = new System.Globalization.CultureInfo("zh-CN");
this.dataSet11.Namespace = "http://www.tempuri.org/DataSet1.xsd";
//
// sqlInsertCommand1
//
this.sqlInsertCommand1.CommandText = "INSERT INTO store(zipcode, area, name) VALUES (@zipcode, @area, @name); SELECT zi" +
"pcode, area, name FROM store";
this.sqlInsertCommand1.Connection = this.sqlConnection1;
this.sqlInsertCommand1.Parameters.Add(new System.Data.SqlClient.SqlParameter("@zipcode", System.Data.SqlDbType.Char, 10, System.Data.ParameterDirection.Input, true, ((System.Byte)(0)), ((System.Byte)(0)), "zipcode", System.Data.DataRowVersion.Current, null));
this.sqlInsertCommand1.Parameters.Add(new System.Data.SqlClient.SqlParameter("@area", System.Data.SqlDbType.Char, 10, System.Data.ParameterDirection.Input, true, ((System.Byte)(0)), ((System.Byte)(0)), "area", System.Data.DataRowVersion.Current, null));
this.sqlInsertCommand1.Parameters.Add(new System.Data.SqlClient.SqlParameter("@name", System.Data.SqlDbType.Char, 10, System.Data.ParameterDirection.Input, true, ((System.Byte)(0)), ((System.Byte)(0)), "name", System.Data.DataRowVersion.Current, null));
//
// sqlSelectCommand1
//
this.sqlSelectCommand1.CommandText = "SELECT zipcode, area, name FROM store ";
this.sqlSelectCommand1.Connection = this.sqlConnection1;
//
// sqlDataAdapter1
//
this.sqlDataAdapter1.InsertCommand = this.sqlInsertCommand1;
this.sqlDataAdapter1.SelectCommand = this.sqlSelectCommand1;
this.sqlDataAdapter1.TableMappings.AddRange(new System.Data.Common.DataTableMapping[] {
new System.Data.Common.DataTableMapping("Table", "store", new System.Data.Common.DataColumnMapping[] {...............................................................
你可以根据自己的需要生成数据集。
加入新列你可以这样做：
DataTable dt;//定义一个表（废话）
dt=dataSet11.Tables ["你的表"];//给表付值DataRow dr;
dr=d
补充：软件开发 , C语言 ,
