网上关于C#连接sal server2005的资料不多，也不全面，对于一个初学者来说要花很长时间看懂。本人经过查找资料和自己的总结，来分享下成果：
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Data.SqlClient; namespace WebTest2.webRoot { public partial class JDBC : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { //建立数据库连接字符串 string connectionString = "server=localhost;database=test;uid=sa;pwd=123"; //将连接字符串传入SqlConnection对象的构造函数中 SqlConnection mySqlConnection = new SqlConnection(connectionString); try { //打开连接 mySqlConnection.Open(); //利用label控件显示mySqlConnection对象的ConnectionString属性 lblInfo.Text = "mySqlConnection对象的ConnectionString属性为：" + mySqlConnection.ConnectionString; lblInfo1.Text += "mySqlConnection对象的ConnectionTimeout属性为" + mySqlConnection.ConnectionTimeout; lblInfo2.Text += "mySqlConnection对象的Database属性为" + mySqlConnection.Database; lblInfo3.Text += "mySqlConnection对象的DataSource属性为" + mySqlConnection.DataSource; lblInfo4.Text += "mySqlConnection对象的PacketSize属性为" + mySqlConnection.PacketSize; lblInfo5.Text += "mySqlConnection对象的ServerVersion属性为" + mySqlConnection.ServerVersion; lblInfo6.Text += "mySqlConnection对象的当前状态为" + mySqlConnection.State; } catch (Exception err) { lblInfo7.Text = "读取数据库出错"; lblInfo8.Text += err.Message; } finally { //关闭与数据库的连接 mySqlConnection.Close(); lblInfo9.Text += "关闭连接后的mySqlConnection对象的状态为"; lblInfo10.Text += mySqlConnection.State.ToString(); } } } } |
注意：如果你的开发工具中没有提示SqlConnection，你需要引入using System.Data.SqlClient;下面教你如何创建出代码中的类：
会生出成三个文件
上面代码在JDBC.aspx.cs中写。
lblInfo.Text 调用的是JDBC.aspx的textBox中的id属性，<asp:textBox></asp:textBox>可以在视图的工具箱拖控件！
