多语言网站中的日期时间文化

Question

我有一个多语种网站，有3种语言：阿拉伯语，法语和英语，但我想在en-US文化中使用datetime（插入，更新和查看），

// Validate culture name
cultureName = CultureHelper.GetImplementedCulture(cultureName); // This is safe
// Modify current thread's cultures            
Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo(cultureName);
Thread.CurrentThread.CurrentUICulture = Thread.CurrentThread.CurrentCulture;

Thread.CurrentThread.CurrentCulture.NumberFormat.CurrencyDecimalSeparator = ".";
Thread.CurrentThread.CurrentCulture.NumberFormat.NumberDecimalSeparator = ".";

我该怎么做？

提前致谢
