DateTime String Format In Asp.net

Here are some of the string formats that you can try out:

Specifier	type	output (June 8, 1970 12:30:59)
dd	Day	08
ddd	Short Day Name	Mon
dddd	Full Day Name	Monday
hh	2 digit hour	12
HH	2 digit hour (24 hour)	12
mm	2 digit minute	30
MM	Month	06
MMM	Short Month name	Jun
MMMM	Month name	June
ss	seconds	59
tt	AM/PM	PM
yy	2 digit year	70
yyyy	4 digit year	1970
:	seperator, e.g. {0:hh:mm:ss}	12:30:59
/	seperator, e.g. {0:dd/MM/yyyy}	08/06/1970

Try this way

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
<Columns>
<asp:BoundField HeaderText="CheckDateFormat" DataField="Date" DataFormatString="{0:M-dd-yyyy}" />
</Columns>
</asp:GridView>
---

DateTime dt = DateTime.Now;
String strDate="";
strDate = dt.ToString("MM/dd/yyyy");   // 07/21/2007 

strDate = dt.ToString("dddd, dd MMMM yyyy");   //Saturday, 21 July 2007

strDate = dt.ToString("dddd, dd MMMM yyyy HH:mm"); // Saturday, 21 July 2007 14:58

strDate = dt.ToString("dddd, dd MMMM yyyy hh:mm tt"); // Saturday, 21 July 2007 03:00 PM

strDate = dt.ToString("dddd, dd MMMM yyyy H:mm"); // Saturday, 21 July 2007 5:01 

strDate = dt.ToString("dddd, dd MMMM yyyy h:mm tt"); // Saturday, 21 July 2007 3:03 PM

strDate = dt.ToString("dddd, dd MMMM yyyy HH:mm:ss"); // Saturday, 21 July 2007 15:04:10

strDate = dt.ToString("MM/dd/yyyy HH:mm"); // 07/21/2007 15:05

strDate = dt.ToString("MM/dd/yyyy hh:mm tt"); // 07/21/2007 03:06 PM

strDate = dt.ToString("MM/dd/yyyy H:mm"); // 07/21/2007 15:07

strDate = dt.ToString("MM/dd/yyyy h:mm tt"); // 07/21/2007 3:07 PM

strDate = dt.ToString("MM/dd/yyyy HH:mm:ss"); // 07/21/2007 15:09:29

strDate = dt.ToString("MMMM dd"); // July 21

strDate = dt.ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss.fffffffK"); // 2007-07-21T15:11:19.1250000+05:30    

strDate = dt.ToString("ddd, dd MMM yyyy HH':'mm':'ss 'GMT'"); // Sat, 21 Jul 2007 15:12:16 GMT

strDate = dt.ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss"); // 2007-07-21T15:12:57

strDate = dt.ToString("HH:mm"); // 15:14

strDate = dt.ToString("hh:mm tt"); // 03:14 PM

strDate = dt.ToString("H:mm"); // 5:15

strDate = dt.ToString("h:mm tt"); // 3:16 PM

strDate = dt.ToString("HH:mm:ss"); // 15:16:29

strDate = dt.ToString("yyyy'-'MM'-'dd HH':'mm':'ss'Z'"); // 2007-07-21 15:17:20Z

strDate = dt.ToString("dddd, dd MMMM yyyy HH:mm:ss"); // Saturday, 21 July 2007 15:17:58

strDate = dt.ToString("yyyy MMMM"); // 2007 July




Hence we can format and getting the datetime value.
