Question

I have Window 7 installed in my computer. The problem is that the system date format is changed some time if computer is restarted. I need to make the date format fixed but don’t know how. I have application built in mvc 3 and have code for string to datetime conversion. If system datetime format doesn’t match with string it show error that
string is not in proper format for converting into datetime which looks for system datetime. The exception is thrown in following code:

 DateTime startDate = Convert.ToDateTime(start);

where,

string start = sundayOfLastWeek.ToString("MM/dd/yyyy HH:mm:ss");

Or, Is there any alternatives so that I can change in code that works all the time despite the system Date Time.

Answer 1

use .ToString(CultureInfo.InvariantCulture) and Parse(value, CultureInfo.InvariantCulture) for values persistance. Only omit CultureInfo if you render values for display purpose. For some specific data formats special formatting rules may exist – follow them.

to recover your data use ParseExact.
