当绑定到依赖对象类时，是否有一种方法隐藏类属性？我是说那些“Dispatcher”、“DependencyObjectType”和“IsSealed”

Jesse，你的问题不是很清楚，但如果我理解正确，你只想显示

SampleObject

中存在的属性，即由你添加的属性，而不是从其基类继承的属性

1。检查PropertyGrid如何获取选定对象的属性-

它应该获取选定对象类型的属性，而不是对象本身的属性-

Type type = this.SelectedItem.GetType();

properties =TypeDescriptor.GetProperties(type);

而不是-

properties = TypeDescriptor.GetProperties(this.SelectedItem);

2。如果这不能解决问题，或者如果您希望对PG中显示的属性进行更多控制，则可以创建自定义属性。为了实现这一点，我创建了一个自定义属性（类似于

IsBrowsable

），您只需使用该属性装饰您的属性并修改属性网格实现即可

这是属性类-
