Well, I wouldn't do it, but I suppose you could add a reference to

Namespace: Microsoft.VisualBasic

Module: DateAndTime

Assembly: Visual Basic Runtime Library (in Microsoft.VisualBasic.dll)

Instead of DateDiff, use a TimeSpan[^]:

C#

TimeSpan diff = (DateTime)rs["test_date"] - DateTime.Now;
int daysAway = diff.TotalDays;
sb.AppendFormat("{0} days away", daysAway);
