当上一个项目已经使用时，如何让这段代码选择数组中的下一个项目
有了链接，它做得很好（看起来）。它只正确添加第一个文件名，其他文件名为"System.String[]"

*注意：为了缩短代码，我在这里只放了两个链接，而不是8个。

如何使此代码在已使用最后一项时选择数组中的下一项

这有帮助吗？引入了一个类来保存链接和本地文件名。我想这就是你想要的。然后为每个链接/文件名组合排队一个条目。我宣布这个班在最前面，只是为了让大家团结起来。

    class LinkAndFileName
    {
        public LinkAndFileName(string initLink, string initFileName)
        {
            link = initLink;
            fileName = initFileName;
        }
        public string link { get; set; }
        public string fileName { get; set; }
    }

    private static Queue<LinkAndFileName> _items = new Queue<LinkAndFileName>();
    private static List<string> _results = new List<string>();
    static string dl_loc = "C:''ProgramData''jyrka98''";
    public static void Start()
        {
            LinkAndFileName[] file_link_array = new []
            {
                new LinkAndFileName("LINK1", "xvm_main_files.zip"),
                new LinkAndFileName("LINK2", "jyrka98_xvm.zip"),
                new LinkAndFileName("LINK3", "premium_hangar.zip"),
                new LinkAndFileName("LINK4", "J1mB0_crosshair.zip"),
                new LinkAndFileName("LINK5", "J1mB0_contour_icons_v1.zip"),
                new LinkAndFileName("LINK6", "J1mB0_contour_icons_v2.zip"),
                new LinkAndFileName("LINK7", "multiline_tank_carousel.zip"),
                new LinkAndFileName("LINK8", "white_dead_tanks.zip"),
            };
            foreach (LinkAndFileName fileLink in file_link_array) { _items.Enqueue(fileLink); }
            DownloadItem();
        }
    private static void DownloadItem()
    {
        if (_items.Any())
        {
            LinkAndFileName nextItem = _items.Dequeue();
            WebClient WC = new WebClient();
            WC.Headers.Add("user-agent", "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:23.0) Gecko/20100101 Firefox/23.0");
            WC.DownloadFileCompleted += new AsyncCompletedEventHandler(WC_DownloadFileCompleted);
            WC.DownloadFileAsync(new Uri(nextItem.link), Path.Combine(dl_loc + nextItem.fileName));
            return;
        }
    }
    private static void WC_DownloadFileCompleted(object sender, AsyncCompletedEventArgs e)
    {
        DownloadItem();
    }
