WPF 实现windows文件压缩文件解压过程动画

目标最终实现整体拆分分步实现1.控件的基底是一个实心的矩形2.在基底上绘制绿色网格线类似棋盘的效果3.有进度条显示进度条是长度可变的浅绿色的矩形块4.有实时速度显示速度大小转为黑色实线在基底中的高度显示5.记录每个黑色实线与浅绿色的矩形块右边缘交点这些交点连线与基底的下边缘组成的轮廓填充成深绿色注意事项一、笔者实现过程中最开始设计自定义控件时继承了ProgressBar然后发现绘制的网格线这些显示不出来继承了ProgressBar的控件的整体模板是跟随ProgressBar的后来改为继承Control。二、绘制顺序可以改变顺序决定了谁覆盖谁的问题比如把黑死速度实线放在靠前位置绘制后面绘制的曲线会遮挡住黑色实线。相关知识WPF 中的DrawingContextBrushGeometryDrawing学习博客会另外写这个进度条控件用到的主要是DrawingContext类自行了解这里以思路和代码为主。完整代码控件using System;
