推荐答案

检查您是否提到过web.config文件中ConnectionString标签或AppSettings标签下的详细信息。



如果连接字符串在ConnectionString标签中，则使用此

Check whether you have mentioned the details under ConnectionString Tag or AppSettings Tag in your web.config file.

If connection string is in ConnectionString Tag then use this

string conStr = ConfigurationManager.ConnectionStrings["ConnectionStringName"].ConnectionString.ToString();

如果连接字符串在AppSettings标签中，那么使用这个

If connection string is in AppSettings Tag then use this

string conStr = ConfigurationManager.AppSettings["ConnectionStringName"].ToString();

System.Configuration.ConfigurationManager.
    ConnectionStrings["connectionStringName"].ConnectionString;

注意：connectionStringName必须与webconfig相同

note:"connectionStringName" must be same as in webconfig

检查web.config是在正确的位置？

你有任何web.config（它覆盖主web.config）在与你的页面相同的文件夹中吗？

Check if the web.config is at its right location?
Do you have any web.config (which overrides main web.config) in the same folder as that of your page?
