web.config文件中的连接字符串 [英] connection string in web.config file

问题描述

在web.config文件中放入连接字符串后我必须在page.aspx.cs页面编写什么编码？

after putting connection string in web.config file what coding i have to do in page.aspx.cs page?

推荐答案

string connection_string = ConfigurationManager.ConnectionStrings [ 你的conn字符串名称] .ConnectionString;





在页面后面的代码中使用它来建立连接到数据库

string connection_string = ConfigurationManager.ConnectionStrings["Your conn string name"].ConnectionString;


use this in code behind page to establish the connection..to database

我假设您要从aspx页面中的web.config文件中检索连接字符串值。如果是这种情况，请看下面的链接，例如
