Question

I have two textbox on my asp.net page which are taking dates from calendar control:

On Calendar selection, I am assigning the value of selected have to hidden variable.
below is the code:

DateTime dtOne;
            dtOne = Convert.ToDateTime(hdnOne.Value.Trim().ToString());
            DateTime dtTwo = Convert.ToDateTime(hdnTwo.Value.Trim().ToString());

When keeping breakpoint I get this value for dtOne

9/2/2011 02:03…

It is working fine in pre prod deployed site, but when I copy paste the same deployed code to the production I am getting below error:

System.FormatException: String was not recognized as a valid DateTime.

Any suggestion why it happened and how to resolve it?

Answer 1

The Culture settings on your server are most likely different from the one your development machine. In this case I would think the DateSeperator is the culprit.

Have you compared the value of hdnOne.Value.Trim().ToString() on both enviromnents?
