C#: Get Properties of a class implemented from an interface

Question

I have been trying to get properties inside a class which implements an interface. My design is as below,

interface ABC
{
  string Name { get; set; }
}

public class BCD:ABC
{
 public string Name { get; set; }
 public string Age{ get; set; }
 public string Height{ get; set; }
 public string Weight{ get; set; }
}

Now using Reflection I have tried this,

main()
{
  ABC abcObj = new BCD();
  var typeOfObject = typeof(abcObj);
  var objectProperties = typeOfObject.GetProperties(BindingFlags.Public|BindingFlags.Instance);
}

What i got in objectproperties were the properties in the ABC class. However i need the properties from the BCD class too.

Can someone help on this?

Have you tried casting it as a BCD class?

Instead of using typeof (as that applies to class/interface names) try

var typeOfObject = abcObj.GetType();

to get the type of the instance.

When I run

ABC abcObj = new BCD();
var objectProperties = abcObj.GetType()
            .GetProperties(BindingFlags.Public | BindingFlags.Instance);

for (int i = 0; i < objectProperties.Length; i++)
{
    Console.WriteLine("{0} ({1})", objectProperties[i].Name, objectProperties[i].PropertyType);
}

I get the following in the console:

Name (System.String)

Age (System.String)

Height (System.String)

Weight (System.String)
