Actually, I didn't know it was possible. Thanks for the article. Yes. Actually, I didn’t know it was possible. Thanks for the article.

In this case we are enumerating over the same collection but returning different, compatible types (though for simplicity in this example I omitted the implicit conversion between MyInt and int). In our final solution, we ended up enumerating over just a single type and provided a separate property for the other type, simply to be more clear to the clients. But it was interesting to discover that enumerating over multiple types in the same class is possible. Thanks for commenting!

Perhaps it would be better to create two properties returning a dedicated enumerable collection (Like the DataGridView class which has "Rows" and "Columns" properties, instead of being directly able to enumerate rows and columns.)
