C# date formating problem

Vinnie

Hi,

I would like to get dd/mm/yy 23:59 format of my date in the text box in aspx.cs code.

First, I select the date from the database into textbox as dd/mm/yy hh:mi, and then
I have to transform it to dd/mm/yy 23:59

Now I do this with this code

string MyDate //which I get from the function and then

textbox1.Text = MyDate.Remove(9)+ "23:59";

Do you know some better solution to do the same but without remove ?

Also, when user insert date like dd/mm/yy without hh:mm, I would like to change it to

"dd/mm/yy 23:59".

How can I check whether the hh:mm part is not inserted ?

Thanks a lot !

The 'mm' needs to be in upper case for months to distinguish it from the minutes component of the DateTime object. This worked fine when I just tried it:

DateTime dt = DateTime.Now;
string myDate = dt.ToString("dd/MM/yy 23:59"));

Sam, thanks a lot !

Still, mydate.ToString("dd/mm/yy 23:59") doesn't work. I had a lot of problems with formating mydate "yyyy-mm-dd hh:mm" to "dd/mm/yy hh:mm", so I expected this :)

Hi,

If possible you should use the DateTime type instead of string to store the Dates and Times.

To convert a DateTime to a string in the format dd/mm/yy 23:59 try

MyDate.ToString("dd/mm/yy 23:59)

As for seeing if the time has been supplied in a string you could try

DateTime MyDate = DateTime.Parse(TheUsersString);

if (MyDate.TimeOfDay.TotalHours == 0d)

{

MyDate.AddHours(23);

MyDate.AddMinutes(59);

}

Hope this helps,

Sam.
