相信大家身邊有很多朋友有時(shí)候請大家投各種票，剛好，這會兒也有朋友找我投票，身為IT程序開發(fā)人員，總覺得投機(jī)取巧一點(diǎn)。

如果僅僅只是點(diǎn)擊即可投票，那相對而言就簡單了，然而，有些網(wǎng)站限制IP，那么情況就不一樣了。

如果您是撥號上網(wǎng)用戶，可以重連路由，改變外網(wǎng)IP地址，不過，這種方式有時(shí)候也不奏效。

于是我采用了IP代理的方式來自動投票。

這樣，一般人會這樣：更改IE瀏覽器的代理設(shè)置，打開IE瀏覽器輸入投票網(wǎng)址（這里需要各位自己找直接投票的url）投票。

但是問題又出來了，每次投票都得重啟瀏覽器才行，我個人覺得瀏覽器打開的一些設(shè)置已經(jīng)保存在了緩存中

雖然在更改代理的時(shí)候更改了注冊表項(xiàng)值，但瀏覽器并沒有實(shí)時(shí)去讀取這個值

因此，鄙人編寫了一個小程序用于自動投票。下面是該程序的關(guān)鍵代碼：

??????? private void StartVote()
??????? {
??????????? this.lbl_daili.Text = lst.Items.Count.ToString(); //獲取代理
??????????? this.wbCnblog.Focus(); //瀏覽器窗口獲取焦點(diǎn)。由于有些投票連接直接彈出alert提示，因此獲取焦點(diǎn)，以自動回車防止程序暫停
??????????? int itemcount = lst.Items.Count;//獲取代理列表，已循環(huán)代理訪問
??????????? string[] urls = new string[itemcount]; //用于保存所有將要訪問的投票鏈接地址
??????????? string[] proxyurl_ip = new string[itemcount];// 代理 IP
??????????? string[] proxyurl_port = new string[itemcount];// 代理 Port
??????????? Random rad = new Random();
??????????? int y = rad.Next(0, 72); // 由于有些網(wǎng)站投票需要限制用戶名，因此隨即生成用戶名（數(shù)組）
??????????? for (int i = 0; i < itemcount; i++)
??????????? {
??????????????? int x = y + i;
??????????????? if (x >= 72)
??????????????? {
??????????????????? x = x % 72;
??????????????? }
??????????????? urls[i] = "http://www.xxoo.com?name=" + mingzi[x];
??????????????? lst.Items[i].Selected = true; //選擇當(dāng)前item,提取IP 以及 端口號，保存在數(shù)組中
??????????????? proxyurl_ip[i] = lst.SelectedItems[0].SubItems[0].Text;
??????????????? proxyurl_port[i] = lst.SelectedItems[0].SubItems[1].Text;
??????????? }
??????????? GetHtml(urls, proxyurl_ip, proxyurl_port); //訪問站點(diǎn)獲取站點(diǎn)內(nèi)容
??????????? Application.Exit();//程序結(jié)束
??????? }

??????? int successcount = 0;

??????? string temp_proxy = "";
??????? string current_proxy = ""; //當(dāng)前代理，用于些日志用到，相當(dāng)于排他鎖的作用

??????? {
??????????? wbCnblog.DocumentText = "頁面加載中...";
??????????? wbCnblog.Navigated += new WebBrowserNavigatedEventHandler(browser_Navigated);//頁面加載時(shí)執(zhí)行 browser_Navigated ,獲取返回內(nèi)容，并寫成功日志
??????????? for (int i = 0; i < urls.Length; i++)
??????????? {
?? ??? ??? ???? loading = true;? //表示正在加載
??????????????? NaviByProxy(? //代理訪問URL
??????????????????????? proxyurls_ip[i], //選中的代理IP地址
??????????????????????? proxyurls_port[i], //選中的代理IP的端口
??????????????????????? urls[i]//url地址
??????????????????????? );
??????????????? while (loading)? //記錄狀態(tài)
??????????????? {
??????????????????? this.txt_info.Text = "正通過代理" + proxyurls_ip[i] + ":" + proxyurls_port[i] + "進(jìn)行投票";
??????????????????? this.textBox_url.Text = urls[i];
??????????????????? current_proxy = proxyurls_ip[i] + ":" + proxyurls_port[i];
