這篇文章只適合初學者，如果你是大蝦，這篇文章就是浪費你的時間。
首先，文件->興建->項目。項目類型：C#，ASP。NET應用程序。
在工具箱中拖一個sqldataadapter到webform窗口中。
向導先點下一步，新建連接，在連接標簽下，選取一個可用的服務器和可用的sqlserver數據庫，確定。
然後配置查詢生成器（太簡單就不說了）。完成。
在webform中點擊sqldataadapter1在屬性欄的下面點生成數據集。單選框用新建，確定。
至此，和數據庫的連接工作基本搞定了，讓我們來操作它吧。
拖一個datagrid到webform 窗口。屬性生成器中選好數據源（我們只有一個dataset)也就這樣了。
然後我們來看看代碼。
切換到代碼窗口，添加黃色的代碼：
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();
//填充數據集
sqlDataAdapter1.Fill (dataSet11);
//綁定
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，如果正常的話你應該可以在datagrid看到你的數據了。
如果你對操作的數據有更高的要求的話（前提是會sql語句），你可以點饑前面綠色代碼前的小加號，修改下面的蘭色代碼。
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[] {....................................
...........................
你可以根據自己的需要生成數據集。
加入新列你可以這樣做：
DataTable dt;//定義一個表（廢話）
dt=dataSet11.Tables ["你的表"];//給表付值
DataRow dr;
dr=d
