I want to convert a Timespan to Datetime. How can I do this?

I found one method on Google:

DateTime dt;
TimeSpan ts="XXX";

//We can covnert 'ts' to 'dt' like this:

dt= Convert.ToDateTime(ts.ToString());

Is there any other way to do this?

It is not very logical to convert TimeSpan to DateTime. Try to understand what leppie said above. TimeSpan is a duration say 6 Days 5 Hours 40 minutes. It is not a Date. If I say 6 Days; Can you deduce a Date from it? The answer is NO unless you have a REFERENCE Date.

So if you want to convert TimeSpan to DateTime you need a reference date. 6 Days & 5 Hours from when? So you can write something like this:

 DateTime dt = new DateTime(2012, 01, 01);
 TimeSpan ts = new TimeSpan(1, 0, 0, 0, 0);
 dt = dt + ts;
