Modify application wide, the display of DateTime

问题:

For an application we develop, we use the "G" format everywhere in our application.

We want to change a little bit this format:

We need to display the first digit after the second.

Ex:

29.07.2014 08:54:36.1

We would like to be able to change this in the CurrentCulture.

It's the only thing we want to change in the current culture, so if before, we were having the following format:

2014/07/29 08:54:36 AM

We then want to have

2014/07/29 08:54:36.1 AM

If before I was having

29.07.2014 08:54:36

We then want to have

29.07.2014 08:54:36.1

A nice to have would be, that if the DateTime we receive, doesn't have a digit to be displayed here( =0 tenth of seconds), to don't have this displayed.

You can set the CurrentCulture for the current thread and specify a deviating LongTimePattern:

CultureInfo culture = Thread.CurrentThread.CurrentCulture.Clone();

change the culture.DateTimeFormat.LongTimePattern = "your pattern";

Thread.CurrentThread.CurrentCulture = culture;

I tested this and looks like is returning what you are looking for except for the "nice to have".

string now = DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss.f tt", CultureInfo.GetCultureInfo("en-US"));

I'd create an extension method for DateTime, something like a ToPrettyPrintStringg() or whatever you wanna call it that returns the date in the format you wish, this way you can get it to display any date the way you want everywhere.
