新手学习wpfbutton中篇实例学习等级4

button进阶

1.等级3的时候学习了用Grid（网格）布局排列。这次是button背景的引用
学习圆角button。我发现学代码难的原因就是英语不好不懂什么意思。
设置focysable属性为false后button就不会在按下的时候一闪一闪的
了.

点击后字体大小button的代码

button5是圆角button代码

   private void FontSize_Click(object sender, RoutedEventArgs e)
        {
                //private 私有的
               //void 空集
            //object 对象；目标
           // sender 发送者
         // Routed已选择路径 
            //Event事件，结果
            //arg 自变量

            if (FOntSize== 12)
            {
                FOntSize= 16;
            }
            else
            {
                FOntSize=12;
            }
        }

        private void button5_Click(object sender, RoutedEventArgs e)
        {
             // message消息 
                //box盒子
                //Show 显示
            MessageBox.Show("圆角button 更改主要属性就是CornerRadius ");

        }

新建一个BindingData.cs的类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace 学习wpf
{
 public   class BindingData
    {
                    //用于按钮4
            public BindingData()                                                             
            {
                ColorName = "Red";
            }
            private string name = "Red";
            public string ColorName
            {
                get { return name; }
                set { name = value; }
            }
    }
}
