HttpRequest 練習－天翼翔幻

我無聊之下就想去試他倒底有幾個結果，目前全測出來大概是 68 個人物

另外這個動作其實就是種砍站的動作，是會造成伺服器負擔的，所以不要太常玩，要不然如果那網管會care的話，可能會ban 你的ip

那這裡主要還是在講解我的 HttpRequest 的練習，首先還是先丟出我的 HttpRequest.cs ，這是以前改的，那大多數時候我都直接套用這個 class 來進行 Request 的傳送及接收的動作

這隻程式主要使用到了 HttpWebRequest 、RegularExpressions 兩種主要工具

有興趣的可以自己研究看看XD

然後我跑了 1~500 共計 500 種的結果，有興趣就自己抓下來看吧，就不要再砍一次了，減輕伺服器的負擔！
