DateTime Problem

[niju]

Hi there
I am trying to get a single digit hour in 12-hour format with the
following code.

DateTime hr = DateTime.Now;
string hour = hr.ToString("h");

However, I get "Input string was not in a correct format" error. Please
help me to correct this problem.

Many Thanks
Niju

Hi Niju,

How does the date that you are passing to the function? Maybe you have to
first use DateTime.Parse() to get it into a format the runtime understands
and than extract your desired format.
Let me know if it helped you or not...

I have no problem getting hour in 24-hour format with the
following code.

DateTime hr = DateTime.Now;
string hour = hr.ToString("hh");

However i cannot get a single digit hour in 12-hour format with the
following code.

DateTime hr = DateTime.Now;
string hour = hr.ToString("h");

Hi niju,

I found the cause of the error :

"This is actually by design. A single character is interpreted as a Standard
DataTime format, "H" & "h"
are not standard DateTime format strings. Hence those two cause exceptions.
A Custom DateTime format needs to be at least 2 characters."

This extract is taken from http://groups.google.com/group/micro...ea90ec4c52d91a

Try this code, it should work :

DateTime hr = new DateTime(2005,5,5,15,13,1);
string hour = hr.ToString("hh");
string hourTrimmed = hr.ToString("hh").TrimStart('0');

Response.Write(hour + "<br>" + hourTrimmed);

Let me know if it helped you or not...
