Solution 3

You are comparing with a string! you can use DOB object itself

Use as below..

C#

if(DOB.Date > DateTime.Now.Date) //Now holds time as well.
{
Label6.Text = ("you have not born yet");
}

Try some thing like below code.

C#

if (DOB.CompareTo(DateTime.Now) > some_integer_value)
           {
               //your required message
           }

Beautiful coding...
I appreciate using "DateTime.TryParse()".

Thanks :)
I alway try to use TryParse methods, because it's a robust approach not so error prone like would be in case of usage Parse methods =)
