Correct Procedures for Testing Against NULLs from SQL Server

Hi all,
I have some C# code that is pulling data from a database where a majority of the values being retrieved areNULL, yet their initial column data types are bothstringandint, which means that I have to temporarily store theseNULL's inintandstringdatatypes in C#. Later on in my code I have to test against these values,and was wondering if I am doing it correctly with the following code.
The following statement the variableor_team_home_idis of astringdata type, but may have had aNULLvalue assigned to it from the database
if (!or_team_home_id.Equals(DBNull.Value)) {}
The following statement the variableor_manager_id is of aintdata type, but also may have aNULLvalue assigned to it from the database.
if (!Convert.IsDBNull(or_manager_id)){}
Are these the correct way to test against NULL values retrieved fromteh database and that are stored in their respective data types.

For string types you could compare with System.DbNull.Value as in (VB.NET)
If strVal IS System.DbNull.Value then

End If
For numeric datatypes I'd recommend doing an ISNULL(column,0) from the SQL stmt so it will be easier/faster to check for 0 from the front end.sql
