Question

我正在尝试用于打开与Azure servicebus订阅的连接。在app.config中我关闭了代理

    <system.net>
            <defaultProxy enabled="false"/>
    </system.net>

当我尝试调用subscriptionClient.Receive（）时，我得到了 NullReferenceException和stack：

我觉得麻烦在

private void ConfigureProxy(HttpWebRequest request, ProxyAuthMode mode)
{
    IWebProxy proxy = request.Proxy;
    Uri uriPrefix = request.Proxy.GetProxy(request.RequestUri);

当代理关闭时，请求.Proxy具有空值。

你知道我怎么解决这个问题。我可以在哪里向ServiceBus团队提交bug？

Answer 1

我是SB团队的成员，我会对此进行审核。你在那里使用哪个版本的ServiceBus程序集？

也就是说，启用defaultProxy意味着什么，只能回到WinINet（IE）默认选项，如果你没有代理，那么你会很好。

无代理连接到Azure ServiceBus
