PropertyGrid控件的默认内置编辑器

Question

我似乎无法在任何地方找到答案.默认编辑器/转换器构建到3.5 Framework PropertyGrid控件中.否则我可以抛出哪些对象类型,它能够可靠地显示和编辑？我发现了很多关于使用自定义编辑器的教程(我可能会在某些时候做).但是现在我的程序中我允许用户创建自己的自定义属性,我想知道我应该允许哪些对象类型,假设他们将在PropertyGrid中编辑它们.

您可能想查看派生自UITypeEditor（在System.Drawing.Design命名空间中）的类。这些类型将作为参数传递给EditorAttribute（在System.ComponentModel命名空间中）。

您还可以查看该类型的元数据以查看EditorAttribute应用的位置。但是，不要在这里使用反射，因为这不是PropertyGrid类使用的。

而是使用TypeDescriptor类来获取类型上的属性的属性描述符（调用静态GetProperties方法）。然后，使用该PropertyDescriptor实例，调用该GetEditor方法以获取该属性的编辑器实例。
