推荐答案

Handle Control.Paint事件(用于控件或表单)或覆盖Control.OnPaint.在这两种情况下，都使用从偶数参数获取的System.Drawing.Graphics实例.使用此实例，使用System.Drawing.Graphics.Draw...方法呈现所需的任何内容.



经OP澄清后:

我的方法将为此工作.您可以使用自定义Control并覆盖OnPaint，或更简单地，仅使用Panel和Paint事件.更改组合键时，请不要忘记:您需要致电Control.Invalidate.而已.会成功的.

替代建议:可能您的图形元素太简单了.尝试在Unicode中找到一些好的字符(使用标准的字符映射"应用程序以查看可用的字符)，并仅使用只读的TextBox和其中的文本.对于垂直线，可以使用代码点"|":0x007C :-)或"∣" 0x2223(数学运算-除法"甚至是│" 0x2502或┃" 0x2503(箱形图，轻垂直/重垂直).
为什么使事情变得比其复杂?

Handle Control.Paint event (for a control or a form) or override Control.OnPaint. In both cases, use System.Drawing.Graphics instance obtained from even argument. Using this instance, use System.Drawing.Graphics.Draw... methods to render whatever you want.



After clarification by OP:

My method will work for this. You can use custom Control and override OnPaint or, more simply, use just Panel and Paint event. When you change the key combination, don''t forget: you need to call Control.Invalidate. That''s it. It will do the trick.

Alternative suggestion: may be you graphical element is too simple. Try to find some good character in Unicode (use standard "Character Map" application to see what''s available) and use just a read-only TextBox and just text in it. For a vertical line, you can use code point ''|'': 0x007C :-) or ''∣'' 0x2223 (Mathematical Operations — "Divides" or even ''│'' 0x2502 or ''┃'' 0x2503 (Box Drawing, Light Vertical / Heavy Vertical).
Why making things more complex than they can be?

您还可以考虑使用各种形状控件:
.NET的形状控制 [高级形状控制 [ .NET的Sprite编辑器 [ FormSprite:我爱你杰西卡！ [

You could also consider the various shape controls available:
Shape Control for .NET[^]
Advanced Shape Control[^]

Or if you want to do something really fancy - take a look at:
Sprite Editor for .NET[^].

You can overlay your forms with sprites as is shown in an earlier article:
FormSprite: I Love You Jessica![^]
