asp.net2.0中读取web.config数据库连接字符串

关于数据库连接 数据库连接字符串一般放在web.config文件中 方式有两种 第一种:建立AppSettings节点 <appSettings> <!-- Sql数据库连接字符串 --> <add key="SqlConnectionStr" value="server=.;uid=sa;password=123;database=Fire" /> <add key="SqlConnectionStr2" value="" /> </appSettings> 第二种:在connectionStrings节点配置 <connectionStrings> <add name="book" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=E:\dragonsea\website\book\book\App_Data\book.mdb" providerName="System.Data.OleDb" /> </connectionStrings> 文件中获取连接字符串 针对第一种方式要通过AppSettings来获取 第一种方式: string strConn = ConfigurationSettings.AppSettings["SqlConnectionStr"]; 第二种方式: string strConn = ConfigurationManager.AppSettings["SqlConnectionStr"]; 针对第二种方式: string strConn = ConfigurationManager.ConnectionStrings["book"].ToString();

取连接字符串
string connString = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["SqlConnStr"].ConnectionString;

web.config文件:
<connectionStrings>
<remove name="LocalSqlServer" />
<add name="SqlConnStr" connectionString="user id=sa;password=sa;initial catalog=YktSms;data source=bing\sql2000" />
</connectionStrings>
