Vin K, that code can be written as the following :

BookId = dRow["BookId"] as int?;

It could have been a good thing if the ?? operator worked with dbnull values returned from a database. These values are ussually checked prior to assigning to some variable

For example
If only i could do this

BookID = (int?)dRow["bookid"] ?? null;

instead of this

if (dRow["bookid"] != DBNull.Value)
{ BookID = (int?)dRow["bookid"]; }
else
{ BookID = null; }

I ‘ll put it on my next wishlist
