vb.net – 使用appsettings,但“ConfigurationSettings”方法已过时

我试图在我的vb.net 2.0 Web应用程序中访问appsettings键值.

我把密钥放在app.config文件中：

<appSettings>
    <add key="DownloadURL" value="http://<myURL>/" />
</appSettings>

我按照说明here,它说我需要像这样访问这个键：

URL = System.Configuration.ConfigurationSettings.AppSettings("DownloadURL")

但我收到以下消息：

Public Shared Readonly property
AppSettings() As
‘System.Collections.Specialized.NameValueCollection’
is obsolete: ‘This method is obsolete,
it has been replaced by
System.configuration!System.configuration.configurationmanager.AppSettings’

我试图用新方法替换旧方法,但它不存在.

很奇怪,因为我用网络应用做了类似的事情,它确实存在.

添加对System.Configuration.dll的引用.

Here’s an explanation.
