Convert/Cast base type to Derived type
- by user102533
I am extending the existing .NET framework class by deriving it. How do I convert an object of base type to derived type?
public class Results { //Framework methods }
public class MyResults : Results { //Nothing here }
//I call the framework method
public static MyResults GetResults()
{
Results results = new Results();
//Results results = new MyResults(); //tried this as well.
results = CallFrameworkMethod();
return (MyResults)results; //Throws runtime exception
}
I understand that this happens as I am trying to cast a base type to a derived type and if derived type has additional properties, then the memory is not allocated. When I do add the additional properties, I don't care if they are initialized to null.
How do I do this without doing a manual copy?
