When parsing datetime into month day with English culture, it is still parsed in Turkish language

Question

Here is the code. I still get incorrect results

string srRegisterDate = "25.07.2009 00:00:00"
CultureInfo culture = new CultureInfo("en-US");
srRegisterDate = String.Format("{0:dddd, MMMM d, yyyy}", Convert.ToDateTime(srRegisterDate), culture);

The result is Cumartesi, Temmuz 25, 2009

Instead it should be Saturday, July 25, 2009

How can i fix this error?

C#.net v4.5.2

Convert.ToDateTime(srRegisterDate) still uses your CurrentCulture which looks like tr-TR based on day and month names. Cumartesi - Temmuz

In String.Format, your culture will be ignored since you used it as a third parameter as an argument but you never use it.

Your code called Format(string format, object arg0, object arg1) overload. But you never use the arg1. This overload doesn't think this is a culture. It thinks it is another argument that you want to format.

This String.Format has an overloads that takes IFormatProvider as a first argument.

• Format(IFormatProvider, String, Object)
• Format(IFormatProvider, String, Object[])
• Format(IFormatProvider, String, Object, Object)
• Format(IFormatProvider, String, Object, Object, Object)

For example;

srRegisterDate = String.Format(culture, "{0:dddd, MMMM d, yyyy}", Convert.ToDateTime(srRegisterDate));

But most comman way (and I always prefer) to get the result that you want is using .ToString() method like;

srRegisterDate = Convert.ToDateTime(srRegisterDate).ToString("dddd, MMMM d, yyyy", culture);
