推荐答案

确保您已在您的项目加入到System.Configuration参考，并放置一个

Ensure that you have added a reference to System.Configuration in your project, and place a

using System.Configuration;

语句。在 ConfigurationManager中键入现在应该是可用的。

statement at the top of your source. The ConfigurationManager type should now be available.

string connectionString = ConfigurationManager.ConnectionStrings["CString"].ConnectionString;
