C# windows窗体应用程序设计
本系列最后一篇，以后不会再以博文的方式呈现。
前言
因为疫情的原因，再加上进入到大三，考证、学业繁忙。加上还要考研的目标，断更了很久。各位看我文章入坑的小伙伴，先说一声抱歉。我想做很多系列，列了很多规划，但这一切都被改变得太快。（本来打算大二上期复习考证等一些列计划全推到本学期，再加上本学期各种专业认知实习）所以后面有些系列更新很慢甚至几乎不会再更新了。在我规划好了时间后，我决定每周末来给大家更新，周末我是专门留着搞其他事情的，其他时间就专心学业和考试。我争取做到每周一更。觉得需要取关的可以取关，我理解。更新强度达不到之前的样子，不能实现之前的规划蓝图。总之，感谢大家的支持。
以下是本篇文章正文内容
一、俄罗斯方块的实现
俄罗斯方块是一款比较经典的游戏，即使没玩过是有听说过的，现在一些节目魔改了俄罗斯方块的玩法，给大家带来了更多的乐趣。现在，动动你的小脑袋，一起来写一个简易的俄罗斯方块游戏吧。
二、步骤
1.部分函数代码
主函数代码如下：
namespace Tetris
{
partial class frmMain
{
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.IContainer components = null;
/// <summary>
/// Clean up any resources being used.
/// </summary>
/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region Windows Form Designer generated code
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{

2.说明（分析代码时会用到）
判断格子的状态
绘图只能在绘图时间里面才有效果，paint（绘图事件）
map[hang,lie]==1 //图形
map[hang,lie]==2 //边界
如果是边界颜色变化
else //其他
绘制三个边界
for(int hang = 0 ;hang<map.getlength(0);hang++)
//左边边界
map[hang,0]=2;
//右边边界
map[hang,mapgetlength(1)-1]=2
3.好的，展示完毕
是的，哎。代码虽然写了，但是由于是上学期的事情，很多东西都忘了。而且vs2019我已经卸载掉了。只能把这个代码整个搞出来给大家学习使用。所以也没办法展示截图，抱歉。
4.总结
本次实例需要写五个窗体，整个的大致方法和流程可以参考前面我更新的有关C#的实例应用。这也是最后一次更新水 这个系列。我会把源代码传到平台上，关注一下就可以免费下载。代码里面的各种属性以及运行后的效果可以根据自己的需求修改。具体的方法和内容可以参考以前我写的内容以后大部分大项目我都会直接在文章底下发链接，供大家下载，当然需要找什么文件都可以在底下评论。之前的内容我会慢慢整理出来。
