跟踪 HTTPWebRequest 的进度
如何跟踪 HTTPWebRequest 的上传进度？当我分散 Debug.WriteLines() 来跟踪代码的哪些部分花费了最长的时间时，我发现花费最长时间的函数是
var res = req.GetResponse();
我可以使用 BeginGetResponse() 但我仍然无法跟踪进度？我从各种文章中读到，在写入请求流时我应该跟踪进度，但我认为这发生在本地，因此几乎是瞬时的。
对于 WebClient，有 webClient.UploadProgressChanged允许我跟踪进度，但我想我不能使用 MultipartFormData 吗？而且我不能一次进行多个上传，但这并不是什么大问题，在我的简单应用程序中，
我如何使用 HTTPWebRequest 跟踪上传/下载进度？
How can I track upload progress of HTTPWebRequest? When I scattered Debug.WriteLines() to track which parts of my code takes the longest time, i found out the function that took the longest time is
var res = req.GetResponse();
I could use BeginGetResponse() but I have no way of tracking progress still? I read from various articles that I should track progress when writing to request stream, but I suppose that happens locally and thus is nearly instantaneous
With WebClient, there is webClient.UploadProgressChanged that allows me to track progress, but I think I can't use MultipartFormData with that? And I can't have multiple uploads at once, not a really big deal tho, in my simple app
How can I then track upload/download progress with HTTPWebRequest then?
