推荐答案

请参阅 读取 Web.Config 和 App.Config 以及企业库 DAAB 设置中的连接字符串(在 Wayback 机器上，因为原始文件已被删除)

Please see Reading Connection Strings in Web.Config and App.Config and Enterprise Library DAAB Settings (on the Wayback Machine as the original got deleted)

ConnectionStringSettings connection = ConfigurationManager.ConnectionStrings["MyConnectionString"]
string connectionString = connection.ConnectionString

您可能需要添加对 System.Configuration
