如何在C＃中的应用程序中在客户端获取远程服务器的日期和时间？

Question

我在应用程序中为用户设置了截止时间，因此，我不想考虑当前的系统时间，而是希望考虑远程服务器计算机的时间，因此如何在c＃中获取远程服务器的日期和时间。

Answer 1

Write a request handler on your server that sends the date time. Without more details, its difficult to know how to implement that.

Answer 2

Write a simple web service that when invoked returns the timestamp (possibly using UTC or something).

[WebMethod]
    public string ServerDateTime()
    {
        serverDate = DateTime.UtcNow;
        return serverDate.ToString();
    }

You could be even lazier and have a standard asp.net page that has the same web method as well. Example: http://softwaredevscott.spaces.live.com/blog/cns!1A9E939F7373F3B7!484.entry
