http://stackoverflow.com/questions/1274852/the-name-configurationmanager-does-not-exist-in-the-current-context
解決方法:需要添加引用 system.configuration
The name 'ConfigurationManager' does not exist in the current context
It's not only necessary to use the namespaceSystem.Configuration
.
You have also to add the reference to the assembly System.Configuration.dll
==============================================================
寫
<appSettings>
<add key="Host" value="smtp.163.com" />
<add key="Port" value="25" />
</appSettings>
讀
private string strHost = ConfigurationManager.AppSettings["Host"];

==================================================
另外一個異常 "app.config配置系統未能初始化"
解決方法: appSettings元素調到configSections元素後面就行了。
