我是这个编程世界的新手。所以我有一个任务是通过 C# 控制台应用程序从 url 下载 zip 文件，我已经尝试了很多方法，但仍然遇到相同的错误。我已经基于 Fiddler 结果在我的代码中添加了一些标头。

这是我的代码：

WebClient webclient = new WebClient();
            webclient.Headers.Add("sec-ch-ua-mobile", "?0");
            webclient.Headers.Add("sec-ch-ua-platform", "windows");
            webclient.Headers.Add("upgrade-insecure-requests", "1");
            webclient.Headers.Add("user-agent", "mozilla/5.0 (windows nt 10.0; win64; x64) applewebkit/537.36 (khtml, like gecko) chrome/98.0.4758.102 safari/537.36");
            webclient.Headers.Add("accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,/;q=0.8,application/signed-exchange;v=b3;q=0.9");
            webclient.Headers.Add("sec-fetch-site", "cross-site");
            webclient.Headers.Add("sec-fetch-mode", "navigate");
            webclient.Headers.Add("sec-fetch-user", "?1");
            webclient.Headers.Add("sec-fetch-dest", "document");
            webclient.Headers.Add("accept-encoding", "gzip, deflate, br");
            webclient.Headers.Add("accept-language", "id-id,id;q=0.9,en-us;q=0.8,en;q=0.7,ms;q=0.6,th;q=0.5");
            webclient.DownloadFile(url, @"d:\data.zip");

有遗漏吗？或者我应该采取其他方式？

谢谢问候，阿尔文

i'm new in this programming world. So i got a task to download zip file from url via C# Console Application, i've tried many things but still got same error. I've already add some Headers in my code also based on Fiddler Result.

This is my code:

WebClient webclient = new WebClient();
            webclient.Headers.Add("sec-ch-ua-mobile", "?0");
            webclient.Headers.Add("sec-ch-ua-platform", "windows");
            webclient.Headers.Add("upgrade-insecure-requests", "1");
            webclient.Headers.Add("user-agent", "mozilla/5.0 (windows nt 10.0; win64; x64) applewebkit/537.36 (khtml, like gecko) chrome/98.0.4758.102 safari/537.36");
            webclient.Headers.Add("accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,/;q=0.8,application/signed-exchange;v=b3;q=0.9");
            webclient.Headers.Add("sec-fetch-site", "cross-site");
            webclient.Headers.Add("sec-fetch-mode", "navigate");
            webclient.Headers.Add("sec-fetch-user", "?1");
            webclient.Headers.Add("sec-fetch-dest", "document");
            webclient.Headers.Add("accept-encoding", "gzip, deflate, br");
            webclient.Headers.Add("accept-language", "id-id,id;q=0.9,en-us;q=0.8,en;q=0.7,ms;q=0.6,th;q=0.5");
            webclient.DownloadFile(url, @"d:\data.zip");

Is there any missed? or should i take other way?

Thanks
