Question

此代码永远悬而未决，不是检索请求/响应流，而是在WebRequest的创建中：

public static void PublishFileList(List<string> files, string url) {
    string content = files.Aggregate<string>((res, file) => res+file+"\n");
    byte[] contentBytes = Encoding.UTF8.GetBytes(content);
    WebRequest request = WebRequest.Create(url);
    Console.WriteLine(content);
    request.GetRequestStream().Write(contentBytes, 0, contentBytes.Length);
    request.GetRequestStream().Close();
    request.GetResponse().Close();
}

永远不会执行WriteLine调用。这是使用有效的URL调用的：

PublishFileList(files, "http://example.com/update");

我不知道原因。我之前使用过WebRequests，这种情况从未发生在我身上（也不是其他任何人，显然，因为谷歌搜索没有给出任何结果）

编辑：

这是调用堆栈：

[Managed to Native Transition] in 
System.Net.WinHttpWebProxyBuilder.BuildInternal () in 
System.Net.WebProxyDataBuilder.Build () in 
System.Net.AutoWebProxyScriptEngine.GetWebProxyData () in 
System.Net.WebProxy.UnsafeUpdateFromRegistry () in 
System.Net.WebProxy..ctor (enableAutoproxy=true) in 
System.Net.Configuration.DefaultProxySectionInternal..ctor (section={System.Net.Configuration.DefaultProxySection}) in 
System.Net.Configuration.DefaultProxySectionInternal.GetSection () in 
System.Net.WebRequest.get_InternalDefaultWebProxy () in 
System.Net.HttpWebRequest..ctor (uri={System.Uri}, servicePoint=(null)) in 
System.Net.HttpRequestCreator.Create (Uri={System.Uri}) in 
System.Net.WebRequest.Create (requestUri={System.Uri}, useUriBase=false) in 
System.Net.WebRequest.Create (requestUriString="http://example.com/update") in 
Updater.MainClass.PublishFileList (files=Cannot evaluate expression because the thread is stopped in native code., url="http://example.com/update") in <redacted>

WebRequest.Create永远挂起
