Convert string to datetime in C#.net

Question

有人可以帮我转换字符串14/04/2010 10：14：49.PM到C＃.net的日期时间而不会丢失时间格式吗？

Answer 1

var date = DateTime.ParseExact(@"14/04/2010 10:14:49.PM", @"dd/MM/yyyy hh:mm:ss.tt", null);

For string representation use

date.ToString(@"dd/MM/yyyy hh:mm:ss.tt");

Also you can create extention method like this:

    public enum MyDateFormats
    {
        FirstFormat, 
        SecondFormat
    }

    public static string GetFormattedDate(this DateTime date, MyDateFormats format)
    {
       string result = String.Empty;
       switch(format)  
       {
          case MyDateFormats.FirstFormat:
             result = date.ToString("dd/MM/yyyy hh:mm:ss.tt");
           break;
         case MyDateFormats.SecondFormat:
             result = date.ToString("dd/MM/yyyy");
            break;
       }

       return result;
    }

Answer 2

DateTime result =DateTime.ParseExact(@"14/04/2010 10:14:49.PM", @"dd/MM/yyyy HH:mm:ss.tt",null);

您现在可以看到格式提供程序的PM或AM和null值

Answer 3

DateTime.ParseExact(@"14/04/2010 10:14:49.PM", @"dd/MM/yyyy hh:mm:ss");

Answer 4

DateTime.Parse(@"14/04/2010 10:14:49.PM");

应该工作，而不是在VS附近，所以我不能尝试

Answer 5

Use convert function

using System;
using System.IO;

namespace stackOverflow
{
    class MainClass
    {
        public static void Main (string[] args)
        {

            Console.WriteLine(Convert.ToDateTime("14/04/2010 10:14:49.PM"));
            Console.Read();

        }
    }
}

Answer 6

I recommend using DateTime.ParseExact as the Parse method behaves slightly differently according to the current thread locale settings.

DateTime.ParseExact(yourString,
    "dd/MM/yyyy hh:mm:ss.tt", null)
