c# - C#下载文件并上传相同的文件作为流抛出SocketException

问题描述

我正在尝试重新上传一些文件。为此，我正在获取下载流并用 StreamContent 包装它。然后尝试上传该流。但我总是得到SocketException。我在这里错过了什么吗？甚至可以将流重定向到另一个地方吗？

_httpClient.DefaultRequestHeaders.Clear();
_httpClient.DefaultRequestHeaders.ConnectionClose = false;

var stream = await _httpClient.GetStreamAsync(fileDownloadInfo.Url);

var streamContent = new StreamContent(stream);

var response = await _httpClient.PutAsync(fileUploadUrl, streamContent);   // throws excepiton

这是完整的异常消息：
