Can I cast from DBNull to a Nullable Bool in one line?

Question

I have a database query which will either return NULL or a boolean (bit) value.

I wish to store this value in a variable of type Nullable<

Answer 1

assuming you have a datareader dr:

bool? tmp = Convert.IsDBNull(dr["dbnullValue"]) ? null: (bool?) dr["dbnullValue"];

---ADDED----

or maybe you can use the ?? if you don't have to check for DBNull but i'm not sure compiler will like this (i cannot test it now)

bool? tmp = dr["dbnullValue"] ?? (bool?) dr["dbnullValue"];
