Question

I have some base objects “Car”, “dog”, “cat” they implement an interface “IGWUIElement”. I have a list of these interfaces: List myList.

At runtime I loop through the list of my elements and by examining the name of the class (using reflection) i need to populate their properties – which are not a part of the interface). I have an xml document descripting the propeties and the value i should assign to them. Here is my interface instantiation.

IGWUIElement newUIElement = (IGWUIElement)Activator.CreateInstance(result);

How do I go about invoking the properties from their name with a particular value (Please note datatypes are limited to int and string). Each object have different properties.

Hope this makes sense…

Answer 1

Use PropertyInfo.SetValue()

PropertyInfo piInstance = typeof(IGWUIElement).GetProperty("property_name");
piInstance.SetValue(newUIElement, value, null);
