3.设计环境本程序选择Visual Studio 2010作为实验环境。

二、设计思路1、用面向对象的方法分析系统对于俄罗斯方块来说，我们可以定义一个类，专门来描述俄罗斯方块，在这个类中，包含与之相关的方法、属性和字段，通过封装，实现其业务逻辑。

其中，每一个俄罗斯方块都有相同的特征，由4个小正方形构成，有旋转，移动，下落的动作，行被填满除去构成行的小正方体块。

基中块的形状类型有7种：田、一、L、倒L、Z、倒Z、上。

在主窗口中，通过调用俄罗斯方块类来实现程序的表示层，在该窗口中通过两个Panel控件来实现方块叠放窗口和下一方块信息窗口；调用设置窗口，保存设计窗口类传回的信息，并设置到游戏中去，保存在配置文件中；2、概要设计根据设计思路，可以为系统设计三个类，实现俄罗斯方块其本块的类RussiaBlock继承Object类，主窗体类MainForm类。

三、流程图四、软件开发过程1、新项目的建立打开 Visual C#.NET 2005，从主菜单中选择“文件”/ “新建”/ “项目”，在弹出的“新建项目”对话框中，在左侧“已安装的模板”中选择 Visaul C#/Windows，在中间位置选择“windows 应用程序”，在“名称”中输入项目名称“RussiaBlock”，最后按确定按钮，建立新项目。

如图 1 所示图1.建立新项目“RussiaBlock”在编辑器右侧文件树上，鼠标右键单击Form1.cs,选择“重命名（M）”，修改名称为：MainForm.cs2、主界面的建立从工具箱中选择合适的控件，加入窗体中。

例如：添加 Label 控件，修改右下侧属性列表中(Name)为 Label1,属性 Text 为手速:如图2所其余控件按下表1所列添加。

图bel 控件的添加表1.添加控件数据主界面完成后效果如图3所示。
