Hello,
I'm trying to fetch intime value from dataset and i got it in string format as like '01/01/1900 10:00:00 AM'
txtintime.Text = (ds.Tables[0].Rows[0][5].ToString().Substring(11, 11));

Output: txtintime.Text = 10:00:00 AM;

It works fine but when i run it on IIS it shows error of index out of range.
So how can i handle this exception.
Plz reply,

Thank you

Please use format datetime only and get your expected result:

C#

DateTime abc = DateTime.Now;
Label3.Text = abc.ToString("MM/DD/YYYY hh:mm:ss tt").Substring(11,11);

This code will help you are alway get the your expected result

C#

txtintime.Text = (ds.Tables[0].Rows[0][5].ToString("MM/DD/YYYY hh:mm:ss tt").Substring(11, 11));

Or, if you know that the string will always be like

"date time AM"

the better way would be to use split

C#

string the_string = "01/01/1900 10:00:00 AM";
string[] tmp_split = the_string.Split(' ');

MessageBox.Show(tmp_split[1]); 

//the output
//tmp_split[0] = 01/01/1900
//tmp_split[1] = 10:00:00
//tmp_split[2] = AM

And you dont have to count any length. Just get it from the array :)
