Question

请查看我的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Text;
using System.Threading.Tasks;
using static System.Net.Mime.MediaTypeNames;

namespace NGH_V1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.ForegroundColor = ConsoleColor.Blue;
            Console.WriteLine("Hello. Welcome to NGH's 1st Console Application. To Continue, Please Press Enter.");
            string option = Console.ReadLine();

            Console.WriteLine("Press 1 to download the VIP Trainer.Press 2 for Coming Soon!.", option);

            int result;

            if (int.TryParse(Console.ReadLine(), out result))

            {

                if (result == 1)
                {
                    Console.WriteLine("Downloading The Trainer!", option);
                    string remoteUri = "https://nukleus.XXX.com/dashboard/download/Trainer/XXXVIP.CETRAINER";
                    string fileName = XXXVIP.CETRAINER", myStringWebResource = null;
                    WebClient myWebClient = new WebClient();
                    myStringWebResource = remoteUri + fileName;
                    Console.WriteLine("Downloading File \"{0}\" from \"{1}\" .......\n\n", fileName, myStringWebResource);
                    myWebClient.DownloadFile(myStringWebResource, fileName);
                    Console.WriteLine("Successfully Downloaded File \"{0}\" from \"{1}\"", fileName, myStringWebResource);
                }

                else if (result == 2)

                    Console.WriteLine("Info to be released later, ", option);

                else

                    Console.WriteLine("No Such Option!");

            }

            else

                Console.WriteLine("No Such Option!");

            Console.ReadLine();

        }
    }
}

当我运行代码并按1时；我收到以下错误：System.Net.WebException：'远程服务器返回了一个错误：（500）Internal Server Error。但是，当我通过浏览器浏览完全相同的URL时，它下载的文件就很好。我在做什么错了？

我看到代码有2个问题：字符串文件名的值应以双引号开头，我的意思是字符串文件名=“ XXXVIP.CETRAINER”

假设您已在实际代码中完成此操作，则变量myStringWebResource的值将为https://nukleus.XXX.com/dashboard/download/Trainer/XXXVIP.CETRAINERXXXVIP.CETRAINER，您将传递该变量以下载文件。

如果您的文件名是XXXVIP.CETRAINER，则该网址应为 https://nukleus.XXX.com/dashboard/download/Trainer/XXXVIP.CETRAINER

因此，基本上，代码应如下所示：

if (result == 1)
            {
                Console.WriteLine("Downloading The Trainer!", option);
                string remoteUri = "https://nukleus.XXX.com/dashboard/download/Trainer/XXXVIP.CETRAINER";
                string fileName = "XXXVIP.CETRAINER";
                WebClient myWebClient = new WebClient();                    Console.WriteLine("Downloading File \"{0}\" from \"{1}\" .......\n\n", fileName, remoteUri);
                myWebClient.DownloadFile(remoteUri, fileName);
                Console.WriteLine("Successfully Downloaded File \"{0}\" from \"{1}\"", fileName, remoteUri);
            }

无法下载文件
