.net 为什么使用ExtractArchiveFromFile时会出现SocketException

当我尝试使用openstacknetsdk将归档文件上载到Rackspace Cloudfiles时，我得到了一个

System.Net.Sockets.SocketException

，使用

CreateObjectFromFile

上载同一个文件效果非常好

示例代码：

var rackspaceIdentity = new CloudIdentity { APIKey = "xxx", Username = "xxx" };
var rackspaceProvider = new CloudFilesProvider(rackspaceIdentity);

const string bz2File = @"C:\Users\Jan\AppData\Local\Temp\tmp1B64.tmp";

var containerName = DateTime.Now.Ticks.ToString(CultureInfo.InvariantCulture);
rackspaceProvider.CreateContainer(containerName);
rackspaceProvider.EnableCDNOnContainer(containerName, 3600);

Console.WriteLine("Pre CreateObjectFromFile");
rackspaceProvider.CreateObjectFromFile(containerName, bz2File, progressUpdated: x => Console.WriteLine(x.ToString(CultureInfo.InvariantCulture)));
Console.WriteLine("Post CreateObjectFromFile");

var containerName2 = DateTime.Now.Ticks.ToString(CultureInfo.InvariantCulture);
rackspaceProvider.CreateContainer(containerName2);
rackspaceProvider.EnableCDNOnContainer(containerName2, 3600);

Console.WriteLine("Pre ExtractArchiveFromFile");
rackspaceProvider.ExtractArchiveFromFile(bz2File, containerName2, ArchiveFormat.TarBz2, progressUpdated: x => Console.WriteLine(x.ToString(CultureInfo.InvariantCulture)));
Console.WriteLine("Post ExtractArchiveFromFile");

您是否已查看了该网站上的任何其他特定信息？它有几个属性可能有助于了解发生了什么。您可以编辑问题以包含该信息。您还可以检查是否存在

InnerException

。我添加了异常详细信息。使用curl我得到curl:（56）SSL read:error:00000000:lib（0）：func（0）：reason（0），errno 113，因此它可能与.NET/sdk无关……嗯，我看到了当IIS中托管的一个.NET应用程序在后台线程上抛出未捕获的异常时，“远程主机强制关闭了现有连接”。这将使整个应用程序池都消失。
