How to convert string value 28 july 00:00 to datetime in c #
3 answers
how about this
string[] initDate = textBox1.Text.Split(' ');
string[] time = initDate[2].Split(':');
DateTime dt = new DateTime(DateTime.Now.Year, DateTime.ParseExact(initDate[0], "MMM", CultureInfo.CurrentCulture).Month, int.Parse(initDate[1]), int.Parse(time[0]), int.Parse(time[1]), 0);
string newDate = dt.ToString("yyyy-MM-dd tt HH:mm");

Use this
var dateTimeString = "Jul 28 00:00";
var required = dateTimeString.ToDateTime().ToString("yyyy-MM-dd tt hh:mm");
You need to add the following class to your project: ie DateTimeRoutines.cs
using System;
using System.Text.RegularExpressions;
/// <summary>
/// Miscellaneous and parsing methods for DateTime
/// </summary>
public static class DateTimeRoutines
{

public static uint GetSecondsSinceUnixEpoch(this DateTime date_time)
{
TimeSpan t = date_time - new DateTime(1970, 1, 1);
int ss = (int)t.TotalSeconds;
if (ss < 0)
return 0;
return (uint)ss;

You must do this in two steps;
- First, parse your string with English culture (for example
InvariantCulture
) with formatMMM dd HH:mm
. - Second, generate a string representation with a format
yyyy-MM-dd tt HH:mm
using culture withAMDesignator
and are not empty space.PMDesignator
string s = "Jul 28 00:00";
DateTime dt;
if(DateTime.TryParseExact(s, "MMM dd HH:mm", CultureInfo.InvariantCulture,
DateTimeStyles.None, out dt))
{
dt.ToString("yyyy-MM-dd tt 00:00", CultureInfo.InvariantCulture).Dump();
}
This will generate a string 2015-07-28 AM 00:00
.
