Difference between two varchar columns

390 Expert 256MB
Hi,

I have two columns in datagrid which are of type varchar in database .These two columns stores start time and end time value.Now I want to have one column which will store the difference between start and end time.
How to do that. For example my start time stores 09:20 and and time value is 09:30 ,but these are two varchar fields in database.

Expand|Select|Wrap|Line Numbers
  1. DateTime dt1 = DateTime.Now;
  2. DateTime dt2 = DateTime.Now;
  3. TimeSpan ts = new TimeSpan();
  4. ts = dt2.Subtract(dt1);
That Should get you going.

Cheers
