【wpf】利用wpf写的一个登录界面--美感为零的程序员伤不起

【前言】

上次用swing来搞客户端，连续几天无法攻克技术难题---说是难题是因为 我感觉swing的机制高深莫测，是菜鸟杀手。所以将客户端的技术换成了wpf，以后可能会用java做服务端，看来现代社会多种语言多种技术构成一个解决方案是必须的，话说假如swing难度低一点的话我也不用同时用两种语音了，因为假如要开发效率上去的话，工具类，组件等等都必不可少，可以说我将同一个工具类用两个不同的版本重写过。

好吧，先看看这个登录界面的效果，大家莫怪，这个UI是从网上copy下来的。



ok，得益于wpf的机制，客户端无意外拿下来，但是由于对wpf还是不熟，所以有很多效果，动画都没做出来。过一段时间可能就熟了。下面上代码：
