Access property on dynamic form

Question

How would one access properties on a dynamic form:

Type type = Type.GetType("GMD.Chart_Forms." + chart);
Form form = (Form)Activator.CreateInstance(type); 
form.PROPERTY????? = ...;
form.Show();

I know it's logical that I cannot access it directly becease the information (name of form) will only be available at runtime. But is there a way to access the properties on the dynamic form?

Answer 1

You could use dynamic :

dynamic form = Activator.CreateInstance(type);
form.Property = value;

But you might get a runtime exception if the property doesn't exist.

To avoid this you could add a check to see if the property exists:

它很乱，但你可以检查表单的子控件，直到你达到你想要的控件，然后将它CAST到你知道它的类型，然后访问该属性。
