數據庫連接

1.在webconfig裏面添加：

<appSettings>
    <add key="connStr" value="database=InfoSite;server=.;uid=sa;pwd=stoneak47" />
  </appSettings>

2.寫一個DB類：

public static SqlConnection dataBaseConn()
  {
   SqlConnection conn=new SqlConnection((String)ConfigurationSettings.AppSettings["connStr"]);
   return conn;
  }

3.頁面調用：

SqlConnection conn=DB.dataBaseConn();

  {
   SqlConnection conn=new SqlConnection((String)ConfigurationSettings.AppSettings["connStr"]);
   return conn;
  }
