Yes, lots of people have now suggested Extension methods and that is probably a better idea than my old worn-out static methods (this was written in the pre-2.0 days). I should probably update it a bit.

But, probably not quite the way you've suggested Gregory. The intent of my original class and methods was to work with objects, specifically data in the DataRows of a DataTable (hence my checking for DBNull.Value, which you didn't do in your example).

Here's a quick start of how I might change it:

public static class BBExtensions
{
	public static DateTime GetNonNull(this object Test, DateTime Default)
	{
		if (Test != null && Test != DBNull.Value)
		{
			DateTime TestDT = Convert.ToDateTime(Test);
			DateTime SqlNull = new DateTime(1900, 1, 1);
			DateTime NetNull = new DateTime(1, 1, 1);
			if (TestDT != SqlNull && TestDT != NetNull)
				return TestDT;
			else
				return Default;
		}
		else
			return Default;
	}
	public static int GetNonNull(this object Test, int Default)
	{
		if (Test != null && Test != DBNull.Value)
			return Convert.ToInt32(Test);
		else
			return Default;
	}
}
