C#

public class MyBase
{
   public string CommonProperty { get; set; }
}

public class ClassOne : MyBase
{
   public string  ClassOneProperty { get; set; }
}

public class ClassTwo : MyBase
{
   public string ClassTwoProperty { get; set; }
}

public class program()
{
   var classTwo = new ClassTwo();
   classTwo.CommonProperty = "Some string";
   classTwo.ClassTwoProperty = "Some other string";
   TestFunction(classTwo);

   private void TestFunction(object unknownClass)
   {
       // how do I convert unknownClass to its actual class and access its properties
       // regardless of which type was passed to the function?
   }
}

How to trigger an event when the last data was read from COM port after a certain time with C#?
Is it possible?
