大家好，请帮助我将数据从一个asp.net网站发布到另一个asp.net网站，我使用带有cookie的http-post方法，但是我无法将数据发布到文件上传器，请为我提供帮助将数据发布到另一页的页面(在我必须发布数据的另一页上，有两个文本框，一个文件上传器，两个下拉列表和一个提交按钮).

推荐答案

请参阅我对答案的评论.

这是第一个引起关注的问题:方案为"http"或"https"的URI在哪里?您正在使用string url = "[e-mail]";，它不能是网页URI.仅当您当前在运行中的HTTP服务器上确实已有通过HTTP或HTTPS协议运行的网页时，才可以使用HttpWebRequest上载文件；否则，您可以使用HttpWebRequest上载文件.并且此页面应具有能够接收POST数据并可以对此数据进行处理的服务器端代码.

在显示的代码中，另一个ASP.NET应用程序"根本不存在.

您的问题提出了另一个问题:您是否真正了解HTTP的功能以及Web的工作方式?在我看来，您需要了解它.我什至都不知道，甚至可能从头开始学习.

祝你好运，

Please see my comment to the answer.

This is the first problem which catch an eye: where is the URI with the scheme "http" or "https"? You are using string url = "[e-mail]"; which cannot be a Web page URI. You can upload the file with HttpWebRequest only if your have really existing Web page working through HTTP or HTTPS protocol on a currently running HTTP server; and this page should have the server-side code capable of receiving POST data and doing something with this data.

In the code you show, that "another ASP.NET application" simply does not exist.

Your question raises another question: do you really understand what HTTP does and how the Web works? It seems to me you need to learn about it; I don''t even know what, maybe even learn from scratch.

Good luck with that,
