[（4） 生成效果](#（4） 生成效果)
1.窗体更换皮肤
要在Windows窗体应用程序中更换皮肤，通常需要修改窗体的外观，包括其颜色、字体、鼠标光标和非客户区（如窗口边框、最小化和最大化按钮等）。这可以通过创建一个自定义窗体或使用第三方库来实现。
2.实例
在本实例的自定义窗体中单击鼠标右键，将弹出一个用于更换窗体皮肤的快捷菜单，选择"换皮肤"菜单下的任意子菜单：紫色、蓝色或绿色，程序将为当前窗体更换皮肤。
（1）图片资源管理器Resources.Designer.cs设计
项目之初，先为项目准备好皮肤所需要的图片资源，并把图片设计到Resources.Designer.cs中，具体的设计方法参考本文作者写的其他文章：C#手动改变自制窗体的大小-CSDN博客 https://wenchm.blog.csdn.net/article/details/137027140

}（2）Form1.Designer.cs设计
开始窗体设计，自定义窗体承载皮肤图片的panel控件设计，最小化、最大化、关闭，menuStrip1菜单设计，最重要的用于更换皮肤的ContextMenuStrip控件。
在C#中，ContextMenuStrip控件是用于显示右键菜单的，而ToolStripMenuItem是该菜单中的一个项目。 对于ContextMenuStrip的DropDownItems，它们实际上是ToolStripItem的子类。设计三个ToolStripMenuItem菜单，用于切换不同的皮肤。

}（4） 生成效果
（5）一个遗憾
本实例有一个缺点，就是窗体左上角显示的切换后的皮肤名称（toolStripMenuItem9、10、11）会随着窗体最大化而被拉伸，字体扭曲了，很难看。我没有解决掉也没时间去解决。有兴趣的网友一旦解决了这个缺陷，请贴出来你用好点子。
