在开发中最重要的就是美化form窗口，在开发中，大多都是用会用自主美化的窗口开发程序。
本文只是点多，分为上中下节。分段讲解。
本文主要讲解窗口美化关键步骤。
首先美化窗体，就需要自己绘制最大化 最小化 关闭按钮。
其次就是界面样式，标题区域等
这一步很重要，首先要将窗体属性设置为None。
其次，可以在属性中将背景颜色调整，本教程是酷黑色，用的值为 37,37,38。可以根据自己需求使用自主值。
public WenForm() { InitializeComponent(); RefreshPadding(); SystemButtonAdd(); base.SetStyle( ControlStyles.UserPaint | ControlStyles.DoubleBuffer | ControlStyles.OptimizedDoubleBuffer | ControlStyles.AllPaintingInWmPaint | ControlStyles.ResizeRedraw | ControlStyles.SupportsTransparentBackColor, true); base.UpdateStyles(); //获取显示器的工作区。工作区是显示器的桌面区域，不包括任务栏、停靠窗口和停靠工具栏。 this.MaximizedBounds = Screen.PrimaryScreen.WorkingArea; this.BackColor = Color.FromArgb(37, 37, 38); this.ForeColor = Color.White; }关键构造函数中相关内容，重绘用的最多的就是如上代码，基本上在重绘中使用很平凡。
private void SystemButtonAdd() { buttonPointX = 0; CloseButtonAdd(); MaxButtonAdd(); MinButtonAdd(); ConfigButtonAdd(); SkinButtonAdd(); }接下来绘制系统按钮 ，包含最大化 最小化 关闭 按钮 ，可以根据自己需求增加按钮，例如设置按钮， 皮肤按钮等，本文教程主要绘制 5个按钮 ，代码相近。

本文中 关闭 ，最大化 ，最小化按钮用GDI+画。也可以用图档代替。
设置按钮，和皮肤按钮，在阿里图标库中下载，可以自主下载编辑。
