Answer 1

Try using DateTime.ParseExact . instead of DateTime.Parse

this.Text="22/11/2009";

DateTime date = DateTime.ParseExact(this.Text, "dd/MM/yyyy", null);

Answer 2

DateTime is the structure you'll need to use.

Whenever you just want the date, you can use DateTime.Date to get just the date component.

Now, if you're parsing something in a format which is different to what one would generally expect, you can define the format the parser will look at by using the ParseExact function instead.

DateTime myDate = DateTime.ParseExact(txt_dobI.Text,"dd/MM/yyyy",null);

The list of the actual formats can be obtained from here http://msdn.microsoft.com/en-us/library/8kb3ddd4%28v=vs.110%29.aspx

However in short

dd/MM/yyyy - British/EU/Lots of Places Format

MM/dd/yyyy - American Format

yyyy/MM/dd - Standard Format

I was working with wpf application I did this and it worked out for me.

                DateTime DOB = DateTime.ParseExact(DOBText.Text.ToString(),
               "dd/MM/yyyy", CultureInfo.InvariantCulture);
