這篇文章只適合初學(xué)者,如果你是大蝦,這篇文章就是浪費(fèi)你的時間。
首先,文件->興建->項(xiàng)目。項(xiàng)目類型:C#,ASP。NET應(yīng)用程序。
在工具箱中拖一個sqldataadapter到webform窗口中。
向?qū)赛c(diǎn)下一步,新建連接,在連接標(biāo)簽下,選取一個可用的服務(wù)器和可用的sqlserver數(shù)據(jù)庫,確定。
然后配置查詢生成器(太簡單就不說了)。完成。
在webform中點(diǎn)擊sqldataadapter1在屬性欄的下面點(diǎn)生成數(shù)據(jù)集。單選框用新建,確定。
至此,和數(shù)據(jù)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(shù)據(jù)源(我們只有一個dataset)也就這樣了。
然后我們來看看代碼。
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(shù)據(jù)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(yīng)該可以在datagrid看到你的數(shù)據(jù)了。
如果你對操作的數(shù)據(jù)有更高的要求的話(前提是會sql語句),你可以點(diǎn)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(jù)自己的需要生成數(shù)據(jù)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=dt.NewRow ();//新元組 dr.BeginEdit (); dr["屬性1"]=;
dr["屬性2"]=;
dr["屬性3"]=;
dr.EndEdit (); dt.Rows.Add (dr);//加入元組 DataGrid1.DataBind ();//把改變在datagrid中表示出來,不寫也可以但是沒現(xiàn)象了。 修改的代碼:
dr= tblAuthors.Rows.Find("213-46-8915");//找到元組(缺省為找主碼) dr.BeginEdit(); dr["屬性1"] = "342" ;
dr("屬性2")=“2342”;
dr.EndEdit()
刪除代碼:
drCurrent = tblAuthors.Rows.Find("993-21-3427"); drCurrent.Delete();
以上的操作只是對數(shù)據(jù)集 如果你要把改變保存回數(shù)據(jù)庫還要添一句:
sqlDataAdapter1.Update (dataSet11,"store");
我的文章就此為止。
