从MSDN

ReadOnlyCollection<TimeZoneInfo> zones = TimeZoneInfo.GetSystemTimeZones();
Console.WriteLine("The local system has the following {0} time zones", zones.Count);
foreach (TimeZoneInfo zone in zones)
   Console.WriteLine(zone.Id);

var timeZoneInfos = TimeZoneInfo.GetSystemTimeZones();

上面给出了一个时区列表，其中包括id。

下面是一个程序及其结果的完整列表。

代码:

using System;

namespace TimeZoneIds
{
    class Program
    {
        static void Main(string[] args)
        {
            foreach (TimeZoneInfo z in TimeZoneInfo.GetSystemTimeZones())
            {
                // For a Console App
                Console.WriteLine(z.Id + "," + z.BaseUtcOffset + "," + z.StandardName + "," + z.DisplayName + "," + z.DaylightName);
                // For any other App
                System.Diagnostics.Debug.WriteLine(z.Id + "," + z.BaseUtcOffset + "," + z.StandardName + "," + z.DisplayName + "," + z.DaylightName);
            }
        }
    }
}

结果会随着时间而改变:

这是你要找的链接:

c#系统时区id

您将在这里找到完整的时区列表及其GMToffsets，您可以使用“时区名称”列值按ID查找时区

e.g

TimeZoneInfo objTimeZoneInfo = TimeZoneInfo.FindTimeZoneById("Dateline Standard Time");

您将得到时区信息类，其中包含用于GMT-12:00的日期线标准时区。

时区标识符列表，默认包含在Windows XP和Vista中:查找本地系统上定义的时区

虽然对于Razor你当然可以通过timezoneinfo循环生成选项。getsystemtimezones ()

我猜这就是大多数人想要的:

微软时区索引值

希望微软即使在XP之后也能保持更新。

我知道这是一个老问题，但微软现在似乎已经通过MSDN提供了这一点。

http://msdn.microsoft.com/en-us/library/gg154758.aspx

DateTime dt;
TimeZoneInfo tzf;
tzf = TimeZoneInfo.FindSystemTimeZoneById("TimeZone String");
dt = TimeZoneInfo.ConvertTime(DateTime.Now, tzf);
lbltime.Text = dt.ToString();

这是经过充分测试并为我工作的代码。你可以复制粘贴到你的aspx页面和cs页面。

这是我的博客，你可以在这里下载完整的代码。谢谢。

下面是微软提供的时区列表

这是c#中的SelectListItem (asp .net)

你可以在后台写代码:

public static List<SelectListItem> GetTimezoneList()
{
    try
    {
        // list of timezone
        List<SelectListItem> timezoneList = new List<SelectListItem>();

        timezoneList.Add(new SelectListItem() { Value = "", Text = "Select TimeZone...", Selected = false });
                
        var timezoneInfo = TimeZoneInfo.GetSystemTimeZones();
                
        foreach (var item in timezoneInfo)
        {
            timezoneList.Add(new SelectListItem() 
            {
                Value = item.StandardName, Text = item.DisplayName, Selected = false });
            }
            return timezoneList;
        }
    }
    catch (Exception e)
    {
        throw e;
    }
}

在前端

@Html.DropDownListFor(s => s.TimeZone, YourbackendServiceName.GetTimezoneList(), new { @class = "form-control input-md" })

这将给你所有的时区DisplayName…即印度标准时间 下拉列表
