DrawTools向你展示如何在Windows Form程序中通过鼠标拖动绘制各种图形对象，它实现的固定图形有：矩形框、椭圆、线性和铅笔。并且，你可以通过鼠标选择、移动、删除图形，还可以改变图形大小等各种操作。另外，程序支持你把绘制的图形保存成文件，可以直接把一个文件从资源管理器中拖到程序界面上打开。-DrawTools sample shows how to create a Windows Forms application for drawing graphic objects in a Windows client area using mouse and drawing tools. Drawing tools implemented in this sample are: Rectangle, Ellipse, Line, and Pencil. There are well-known techniques for creating such type of applications, like: interaction with mouse, flicker-free drawing, implementing of drawing and selection tools, objects selection, managing of objects Z-order etc. MFC developers may learn all this stuff from MFC sample DRAWCLI. DrawTools C# program reproduces some of DRAWCLI functionality and uses some design decisions from this sample.

简单的运动小球，其中多处运用到var变量的使用，希望大家多多支持!-simple ball movement, a number of which applied to the use of variable var hope that everyone can support!

该程序类似WINDOWS自带的画图程序，只是后面还有些功能还没写完整，以后有时间将其补充完整，不过对于初学者来说程序里有很多东西值的借鉴，特别是多态的使用和菜单的操作，还有文档的保存…… -The program

此程序是一个打开和保存位图的，自己定义了一个DIB类。-This procedure is an open and save bitmap, DIB own definition of a category.
