帮同学搞个课程设计winform连接sqlserver2005
具体方法：
.添加App.config文件
2.在App.config文件中添加节点
<?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings> <add key="connString" value="Data Source=LIBL;Initial Catalog=HoverTreeSCJ;User ID=sa;Password=sa"></add> </appSettings> </configuration>
HoverTreeSCJ 为数据库的名称
3.在项目Reference中添加引用 System.configuration
在文件中 添加引用 using System.configuration;
using System.Data.SqlClient;
4.获取App.config中的连接字符串
public string ConnString = System.Configuration.ConfigurationManager.AppSettings["connString"];
5.连接数据库，读取数据
SqlConnection conn = new SqlConnection(ConnString); string strSql = "SELECT * FROM Basetb"; SqlCommand cmd = new SqlCommand(); cmd.CommandText = strSql; cmd.Connection = conn; conn.Open(); SqlDataReader dr = cmd.ExecuteReader(); if (dr.HasRows) { while (dr.Read()) { this.textBox1.Text = dr[0].ToString(); } } conn.Close(); /* hovertree.top */
