Loading a Null value into an int variable

Asked by gjok in C# Programming Language, Programming for ASP.NET, .NET Framework 2.0

Tags: C#

I am loading values from a database record into a class. One of the class properties is an int, which corresponds to an int fiel in the database.
However, sometimes the DB value in null, which causes an exception when assigning the value to the class property.

I know I can set defaults on the database, but I am more curious to learn how to handle this kind of problem for future reference.
What is the standard proceure for dealing with this problem?

private int? _sslPort;
 
public int? SSLPort
{
  get { return _sslPort; }
  set { _sslPort = value; }
}
 
Domain myDomain = new Domain();
myDomain.SSLPort = int.Parse(dr["SSLPort"].ToString()) ?? 0; // Error
myDomain.SSLPort = Convert.ToInt32(dr["SSLPort"]) ?? 0; // Error
