如何使用C#获得机器时间 [英] How to get Machine time Using C#

问题描述

大家好，

我创建了一个网站并进行了托管，因此当客户端登录那里的登录状态时，我需要如何使用C#获取客户端计算机时间.我尝试使用Datetime.now方法，但是此方法仅获取服务器时间.所以请帮助我如何使用C#获得客户端计算机的时间，

(或)
Timezoneinfo我的代码中不支持，如何在c#编码中添加Timezoneinfo方法以将时间服务器转换为本地.

Hi Guys,

I created one website and hosted it, so i need how to get client machine time using C# when client sign in there login status. i tried Datetime.now method but this method get server time only. so please help how can i get client machine time using c#,

(or)
Timezoneinfo Does not support in my code, how can i add Timezoneinfo method in c# coding to convert time server to local.

推荐答案

您无法获取时间格式客户端PC使用C#，因为后台代码是在SERVER上执行的，而不是在客户端上执行的.您可以使用JavaScript从浏览器获取当前时间.
看看以下链接

You can''t get the time form the client PC using C# because the code-behind is executed on the SERVER, not in the client. You canuse JavaScript to get the current time from the browser.

在C#中无法做到这一点，您必须在javascript中获取时间偏移:

Hi,

There is no way to do it in C#, you have to get the time offset in javascript:

<script type="text/javascript">
    

     function GetLocalTimeOffset(id)
     {
       var now = new Date();
       var offset = now.getTimezoneOffset();
        

        var hidTimeZone = document.getElementById(id);
        if(hidTimeZone != null)
        {
            hidTimeZone.value = offset;
        }
     }
     

    </script>

通过使用隐藏字段将其存储在会话中，然后可以使用诸如此类的方法获取日期(查看我的助手类):

Store it in session by using the hidden field, and after you can get the date with some methods like this (look my helper class):

public static class DateTimeHelper
    {
        private const string dateTimeStringFormat = "dateTimeStringFormat";
        private const string timeStringFromat = "timeStringFormat";
        private const string dateStringFormat = "dateStringFormat";

        public static string GetDate(DateTime date)
        {
            string format = ConfigurationManager.AppSettings[dateStringFormat];
            return date.ToString(format, new CultureInfo("en-US"));
        }

        public static string GetDate(DateTime date, double timeZoneOffset)
        {
            string format = ConfigurationManager.AppSettings[dateStringFormat];
            return ConvertUtcToLocal(date, timeZoneOffset).ToString(format, new CultureInfo("en-US"));
        }

        public static string GetTime(DateTime time, double timeZoneOffset)
        {
            string format = ConfigurationManager.AppSettings[timeStringFromat];
            return ConvertUtcToLocal(time, timeZoneOffset).ToString(format, new CultureInfo("en-US"));
        }

        public static string GetDateTime(DateTime dateTime, double timeZoneOffset)
        {
            string format = ConfigurationManager.AppSettings[dateTimeStringFormat];
            return ConvertUtcToLocal(dateTime, timeZoneOffset).ToString(format, new CultureInfo("en-US"));
        }

        private static DateTime ConvertUtcToLocal(DateTime dateTime, double timeZoneOffset)
        {
            //Move to universal time (GMT) with Zero offset 
            DateTime utcDateTime = dateTime.ToUniversalTime();
            //Add client side offset
            return utcDateTime.AddMinutes((-1) * timeZoneOffset);
        }
    }
