向大家分享在项目中编写的比较实用的控件：MyTextBox，对textbox进行了扩展

lib文件夹中放的是控件的源码dll，该dll包含大量本人在这几年项目中的控件，现在逐步编写到github上，github地址

• Mask 水印提示
• MaskForeground 水印提示文字文字
• MaskFontSize 水印提示文字大小
• MaskHorizontalAlignment 水印提示横向对齐
• MaskVerticalAlignment 水印提示纵向对齐
• TextInputType 输入类型：Default（都可以）、Digital（纯数字）、Letter（纯字母）、InputMethodEnabled（关闭输入法）、DigitalWithOemPeriod（带小数点的数字）、DigitalWithMinus（有符号的数字）、DigitalWithMinusAndOemPeriod（有符号的数字，支持小数点）
• Units 小数位数（配合TextInputType的类型）
• IntCount 数字的位数（配合TextInputType的类型为纯数字）
• LeftContent 输入框左侧内容
• RightContent 输入框右侧内容
• TextDigitalHelper 是一个附加属性类，控制输入类型，可应用到普通的TextBox上
• ControlAttachPropertyHepler 是一个附加属性类（从网上的版本修改了很多），对网络图标字体进行了友好支持，详情看MyWPFUIBaseDemo,以后会重点优化
