CultureInfo 类在 .NET 应用程序中提供特定于语言的信息。此信息包括语言、子语言、国家或地区、日期名称、月份名称、日历等。它还提供数字、货币、日期或字符串的文化特定转换。在下面的教程中，我将向您展示如何从 .NET Framework 中可用的不同文化中检索此信息。

要使用 CultureInfo 类，您需要导入 System.Globalization 命名空间，其中包含以下代码中使用的许多类，例如 RegionInfo、DateTimeFormatInfo 或 NumberFormatInfo。

以下代码将在列表框中加载 .NET Framework 中可用的所有特定区域性。

private void Form1_Load(object sender, EventArgs e){// Load All Specific CulturesCultureInfo[] allCultures = CultureInfo.GetCultures(CultureTypes.SpecificCultures);foreach (CultureInfo culture in allCultures){listBox1.Items.Add(culture.EnglishName );}
}

当用户从列表框中选择任何语言时，以下代码检索该语言，设置当前应用程序和用户界面语言，然后在不同标签上显示特定于语言的信息。

private void listBox1_SelectedIndexChanged(object sender, EventArgs e){try{CultureInfo[] allCultures = CultureInfo.GetCultures(CultureTypes.SpecificCultures);int index = listBox1.SelectedIndex;CultureInfo c = (CultureInfo)allCultures.GetValue(index);// Set Current Application and User Interface CultureSystem.Threading.Thread.CurrentThread.CurrentCulture = c;System.Threading.Thread.CurrentThread.CurrentUICulture = c;label1.Text = "Application Culture Name: " + c.Name;label2.Text = "Application Culture Native Name: " + c.NativeName;label3.Text = "Application Culture English Name: " + c.EnglishName;label4.Text = "Application Culture Neutral Name: " + c.TwoLetterISOLanguageName;label5.Text = "Application Culture Language Name: " + c.ThreeLetterISOLanguageName;label6.Text = "Application Culture Windows Name: " + c.ThreeLetterWindowsLanguageName;// RegionInfo ObjectRegionInfo r = new RegionInfo(c.Name);label7.Text = "Region English Name: " + r.CurrencyEnglishName;label8.Text = "Currency Symbol: " + r.CurrencySymbol;label9.Text = "Region English Name: " + r.EnglishName;// DateTimeFormatInfo Object is used // to get DayNames and MonthNamesstring[] days = c.DateTimeFormat.DayNames;listBox2.Items.Clear();foreach (string day in days){listBox2.Items.Add(day);}string[] months = c.DateTimeFormat.MonthNames;listBox3.Items.Clear();foreach (string month in months){listBox3.Items.Add(month);}// Formatting Currency and Numberslabel10.Text = "Full Date Time Pattern: " + c.DateTimeFormat.FullDateTimePattern;label11.Text = "Formatted Date: " + DateTime.Now.ToString("d", c.DateTimeFormat);label12.Text = "Formatted Number: " + 65000.ToString("C", c.NumberFormat);}catch (Exception ex){ }
