推荐答案

要在runtiome中读取connectionString，请使用以下代码：

TO read the connectionString at runtiome use the follwoing code:

String str=String.Empty;
str = ConfigurationManager.AppSettings["cc"].ToString();

where cc is the variable defined in web.config file for the user defined connection string. It is used like this:

<appsettings>
   <add key="cc" value="server=servername;uid=username;pwd=password;initial catalog=databasename" />
</appsettings>
