C# 使用WebResponse实现当前计划/问题中的任务

我已经为我当前的项目执行了任务，但在那之后，我有一些问题要处理。让我向您展示整个第一个应用程序—未实现任务的实现和修改后的锁定捕获，以及我在这个新版本中遇到的问题。请注意，与旧的是工作良好

应用程序的第一个版本（如果您需要更多代码，请询问）

---

因为我知道特定元素在服务器上并没有响应，所以我把它放在超时文件中。在完成任务之后，我不知道发生了什么。总结第一个应用程序工作正常，第二个不正常。您能支持吗？

这是太多的代码，任何人都读不懂。你应该发布一个小的，完整的重现你的问题。我认为代码要少一些。正在等待您的反馈。对主题有任何反馈吗？
