【wpf】利用wpf寫的一個登入介面--美感為零的程式設計師傷不起

【前言】
上次用swing來搞客戶端,連續幾天無法攻克技術難題---說是難題是因為 我感覺swing的機制高深莫測,是菜鳥殺手。所以將客戶端的技術換成了wpf,以後可能會用java做服務端,看來現代社會多種語言多種技術構成一個解決方案是必須的,話說假如swing難度低一點的話我也不用同時用兩種語音了,因為假如要開發效率上去的話,工具類,元件等等都必不可少,可以說我將同一個工具類用兩個不同的版本重寫過。

好吧,先看看這個登入介面的效果,大家莫怪,這個UI是從網上copy下來的。
ok,得益於wpf的機制,客戶端無意外拿下來,但是由於對wpf還是不熟,所以有很多效果,動畫都沒做出來。過一段時間可能就熟了。下面上程式碼:
