Not know, I use RectangleF type, can use a Rectangle type, but why can't use a custom class begin?

 
Public class AA 
{
Public string a {get; set; } 
Public string b {get; set; } 
} 
AA AA=new AA {="2", b="3"}; 
Public AA _rect {get {return this. AA; } the set {this. Aa=value; Enclosing Invalidate (); }}

Please look at the example on me, so why not in class? Properties panel in this property is still a grey read-only, why

Add [TypeConverter to AA (typeof (ExpandableObjectConverter)]

CodePudding user response:

refer to 6th floor Bridge_go response:

to AA plus [TypeConverter (typeof (ExpandableObjectConverter)]

Out, but it shows that this is not very good, can be customized into a=1, b=2 this form?
