Xamarin.ios 为什么我在Xamarin iOS中的WebRequest在ipv6环境中失败？

xamarin.ios

Xamarin.ios 为什么我在Xamarin iOS中的WebRequest在ipv6环境中失败？,xamarin.ios,ipv6,Xamarin.ios,Ipv6,我设置了一个本地ipv6环境，如下所示我有一个非常简单的iOS Xamarin项目，我什么也不做，只是： WebRequest req = WebRequest.Create("http://109.68.230.138"); WebResponse response = req.GetResponse(); //exception var dataStream = response.GetResponseStream(); StreamReader reader = new StreamRe

我设置了一个本地ipv6环境，如下所示

我有一个非常简单的iOS Xamarin项目，我什么也不做，只是：

WebRequest req = WebRequest.Create("http://109.68.230.138");
WebResponse response = req.GetResponse(); //exception
var dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
string responseFromServer = reader.ReadToEnd();

在第2行，我得到以下异常。如果有人知道它应该如何运行或如何运行，那就太好了。我猜传递ipv4地址仍然是一个常见的用例
