推荐答案

如果您谈论的是WinForms:关于如何在自定义控件中添加对Actions和Designer Verbs之类的设计时支持的最佳系统解释我遇到过的是Matthew MacDonald的2004版"C#中的Pro .NET 2.0 Windows窗体和自定义控件"(APress).

在CP上签出:[ ^ ].

在MSDN上:[ ^ ]

恕我直言，这是一项艰巨的任务.

您可能会记住，定义一个公共枚举，然后将一个公共属性放在您的自定义控件中，类型是该公共枚举的类型将导致在属性编辑器中出现在设计时 ...针对该自定义控件的实例，将其拖动到属性"编辑器中该条目的ComboBox选择中的窗体"上.

那是一个轻松的胜利.

If you are talking about WinForms: the best systematic explanation of how you go about adding design-time support for things like Actions and Designer Verbs in a custom control I''ve come across is in the 2004 edition of Matthew MacDonald''s "Pro .NET 2.0 Windows Forms and Custom Controls in C#" (APress).

On CP check out:[^].

On MSDN:[^]

This is, imho, a non-trivial task.

You might keep in mind that defining a public Enum, and then putting a public property in your custom control, whose type is the type of that public Enum will result in the presence in the Properties Editor at design-time ... for an instance of that custom control dragged onto a Form ... in a ComboBox selection for that entry in the Properties Editor.

That''s an easy win.
