Hi,

I am trying to move my C# code from .Net 3.5 to .Net 4.0. Facing a strange problem.
The following code worked well in .Net 3.5

DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss")

But, for some reason, in the 4.0 run, it produces result like yyyy-MM-dd rather than yyyy/MM/dd . The '/' is replaced by '-' in the output.

I googled around for quite some time.. but no luck. Has someone seen this problem before?

Actually The Format Was Chaged In .Net Framework 4.0 Compare To .Net3.5 It Accepts Format as DateTime.Now.ToString("dd/MMM/yyyy") this format displays the date as
11/Oct/2011 and if changed the month to 2 MM i,e DateTime.Now.ToString("dd/MM/yyyy") and now the date will display in this format: 11/10/2011.

Solution 1

Try the below code,

C#

DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss", DateTimeFormatInfo.InvariantInfo)

The problem is the convert function is using the separator from the Date/Time settings of your machine. The above code should work perfectly.

But this seems strange! Why should the system settings override what I code? Why do I need to explicitly tell the CLR to follow what I have coded? Is it just one of "Microsoft Features"? Or something more to it? Any idea?
