Question

我尝试在Mono项目的Web.config中配置System.net节点。

我一直得到这个例外：

System.Configuration.ConfigurationErrorsException
Error deserializing configuration section defaultProxy: Unrecognized attribute 'enabled'. (/usr/share/nginx/aspnet/Web.config line 1)

Description: HTTP 500.Error processing request.
Details: Non-web exception. Exception origin (name of application or object): System.Configuration.

我无法弄清楚如何让我的应用程序接受defaultProxy节点，并将enabled属性设置为true或使用其他一些设置。

如果从Web.config中删除System.net节点，则使用WebClient的应用程序部分会超时。

Answer 1

我相信你发现了单声道的错误。 DefaultProxySection constructor seems to forget to add the attribute properties to the collection，因此配置阅读器不了解它们。

请注意，enabled属性的默认值为true，因此您可以将该设置省略为解决问题的方法。

尽管如此，请在bugzilla.xamarin.com

中报告错误

Answer 2

Necromancing。
要解决此错误，您可以设置

System.Net.WebRequest.DefaultWebProxy

为NULL或

new System.Net.WebProxy();

在执行WebRequest之前。

示例：

System.Net.WebRequest.DefaultWebProxy = null;
System.Net.WebRequest.DefaultWebProxy = new System.Net.WebProxy();


System.Net.HttpWebRequest request = (System.Net.HttpWebRequest)
System.Net.WebRequest.Create(URL);
