【C#】上机实验八

1. 设计一个窗体应用程序，模拟写字板应用程序的基本功能。具体功能要求如下：

（1）“文件”菜单中有“新建”、“打开”、“保存”、“退出”子菜单。

（2）“编辑”菜单中有“剪切”、“复制”、“粘贴”、“撤销”、“重复”、“全选”子菜单。

（3）工具菜单中有“颜色”、“字体”、“状态栏”功能。

（4）帮助菜单中有“关于”菜单功能。

（5）实现“编辑”菜单中、“工具”栏目中“剪切”、“复制”、“粘贴”、“撤销”、“重复”、“全选”的功能。

（6）实现文件的新建、打开、保存功能。（利用RichTextBox控件）

（7）文件菜单添加打开文本文件、保存文本文件菜单项，实现文件的打开、保存功能。（利用文件读写类）

提示：

（1）添加菜单栏、工具栏、RichTextBox控件。

（2）在打开对话框中要想只显示文本文档，可以在通用对话框Filter属性中设置*.txt类别。richTextBox的LoadFile、SaveFile方法中要指定文件流为RichTextBoxStreamType.PlainText

（3）点击菜单和工具栏相关按钮都实现同一个功能，所以会调用同一个方法。设计一系列公有方法实现相关功能。建议完成一个方法，就运行测试一个方法，问题解决后再编写下一个方法，避免出现太多错误。
