推荐答案

问题是，当您在非浏览器上使用下载网址时，该网址不合适.
还在html输入密码"上拼写错误


让我发布一个完全灵活的代码:

The problem is the url for download is not appropriate when you use it on non-browser..

Also spelling mistake on html input "Password"


Let me post a fully flexible code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections.Specialized;

namespace CodeProjectDownload
{
    class Program
    {
        static void Main(string[] args)
        {
            Download("[e-mail]", "mypassword", @"C:\Test", @"http://www.codeproject.com/KB/IP/SimpleFTPDemo/SimpleFTP20_src.zip");
        }

        private static void Download(string email, string password, string destination, string downloadUri)
        {

            using (CookiesAwareWebClient client = new CookiesAwareWebClient())
            {
                NameValueCollection values = new NameValueCollection();
                values.Add("Email",email );
                values.Add("Password", password);
                values.Add("x", "10"); // <- I doubt the server cares about the x position of where the user clicked on the image submit button
                values.Add("y", "10"); // <- I doubt the server cares about the y position of where the user clicked on the image submit button
                values.Add("login", "login");

                // We authenticate first
                client.UploadValues("https://www.codeproject.com/script/Membership/LogOn.aspx?rp=%2f", values);

                // Now we can download

                string modifieduri = "http://www.codeproject.com/script/articles/download.aspx?file=" + downloadUri.Replace("http://www.codeproject.com","") + "&rp=";


                string filename = System.IO.Path.GetFileName(downloadUri);

                string filepathname = System.IO.Path.Combine(destination, filename);

                client.DownloadFile(modifieduri, filepathname);
            }
        }
    }
}
