如何将格式为"dd/MM/yyyy"的日期字符串转换为OS当前区域性日期格式 [英] How to Convert a Date String with Format “dd/MM/yyyy” to OS Current Culture Date Format

问题描述

字符串具有"dd/MM/yyyy"格式的值，例如"04/10/2012".这应该转换为带有当前操作系统文化的日期.

我已经尝试将以下字符串与朝鲜语作为OS的当前文化使用，其中日期格式为yyyy-MM-dd，我的代码未获得正确的月值，它将月值与日互换:

输入:"04/10/2012"
产出:2012-04-10

代码:

 DateTime DT;
            字符串 dt = " ;
            
            DateTimeFormatInfo DateInfo = CultureInfo.CurrentCulture.DateTimeFormat;
            DT = Convert.ToDateTime(字符串 .Format("  + DateInfo .ShortDatePattern +  }"，dt.Trim()) ，CultureInfo .CurrentCulture);
            MessageBox.Show("  + DT.ToShortDateString()); 

我该如何解决?

解决方案

 DateTime DT;
            字符串 dt = " ;
            
            DateTimeFormatInfo DateInfo = CultureInfo.CurrentCulture.DateTimeFormat;
            DT = Convert.ToDateTime(字符串 .Format(" ，dt.Trim())，CultureInfo .CurrentCulture);
            MessageBox.Show("  + DT.ToShortDateString()); 

string dt = "04/10/2012";
DateTime DT = DateTime.ParseExact(dt, "dd/MM/yyyy", CultureInfo.InvariantCulture);
MessageBox.Show("Date: " + DT.ToShortDateString());

请注意，如果您的"dt"字符串采用其他格式，则此方法将不起作用-潘多拉魔药盒将打开...

A string has the value in "dd/MM/yyyy" format like "04/10/2012". This should be converted to a Date w.r.t Current Culture of OS.

I have tried below string with Korean as Current Culture of OS in which date format is yyyy-MM-dd, my code is not getting correct Month value, it interchange the month value with day:

Input: "04/10/2012"
Output: 2012-04-10

Code:

DateTime DT;
            string dt = "04/10/2012";
            
            DateTimeFormatInfo DateInfo = CultureInfo.CurrentCulture.DateTimeFormat;
            DT = Convert.ToDateTime(String.Format ("{0:"+DateInfo .ShortDatePattern +"}", dt.Trim ()), CultureInfo .CurrentCulture);
            MessageBox.Show("Date: " + DT.ToShortDateString());

How I ca fix that ?

解决方案

DateTime DT;
            string dt = "04/10/2012";
            
            DateTimeFormatInfo DateInfo = CultureInfo.CurrentCulture.DateTimeFormat;
            DT = Convert.ToDateTime(String.Format ("{0:dd/MM/yyyy}", dt.Trim ()), CultureInfo .CurrentCulture);
            MessageBox.Show("Date: " + DT.ToShortDateString());

string dt = "04/10/2012";
DateTime DT = DateTime.ParseExact(dt, "dd/MM/yyyy", CultureInfo.InvariantCulture);
MessageBox.Show("Date: " + DT.ToShortDateString());

Please note that this will not work if your "dt" string is in a different format - the Pandora''s Box of Pain will open...
