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。

Answer 2

您可能希望查看从UITypeEditor派生的类（在System.Drawing.Design namespace中）。这些类型将作为参数传递给EditorAttribute（在System.ComponentModel namespace中）。

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

而是使用TypeDescriptor class来获取类型属性的属性描述符（调用静态GetProperties method）。然后，使用PropertyDescriptor实例，调用GetEditor method以获取该属性的编辑器实例。

Answer 3

您实际上可以在PropertyGrid中抛出任何对象。它会自动完成很多事情。如果您希望获得本机提供的特殊编辑体验，则只需创建自定义UI类型编辑器。即使在这种情况下，你按照属性而不是整个对象来做。

Answer 4

PropertyGrid使用TypeConverters，每种基本类型都有TypeConverters（以及基本类型的集合）。

只要您使用其中一种基本类型或基本类型集合，属性网格就应该能够提供编辑UI。

Answer 5

除了UITypeEditors之外，PropertyGrid还能够显示任何具有TypeConverter的对象，该对象为CanConvertFrom（String）返回true。您可以为特定对象类型实现自己的TypeConverters，以实现此目的。
