How to convert a string with date and time to DateTime data type?

A client is sending a string containing a date in format YYYYMMDDHHmmSS (e.g. 201004224432). There are no separators like / or -.

How can I easily convert this to a DateTime object? Convert.ToDateTime() doe开发者_高级运维s not work.

Use DateTime.ParseExact:

var date = DateTime.ParseExact(
                       "201004224432", 
                       "yyyyMMddHHmmss",
                       CultureInfo.InvariantCulture);

Note the tweaks to your format string to work appropriately.

You want DateTime.ParseExact, which can take in a formatting string like yours and use it to parse the input string.

use this code sample

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms;

namespace DateTimeConvert { public partial class Form1 : Form { public Form1() { InitializeComponent(); }

    private void button1_Click(object sender, EventArgs e)
    {
      label1.Text= ConvDate_as_str(textBox1.Text);
    }

    public string ConvDate_as_str(string dateFormat)
    {
        try
        {
            char[] ch = dateFormat.ToCharArray();
            string[] sps = dateFormat.Split(' ');
            string[] spd = sps[0].Split('.');
            dateFormat = spd[0] + ":" + spd[1]+" "+sps[1];
            DateTime dt = new DateTime();
            dt = Convert.ToDateTime(dateFormat);
            return dt.Hour.ToString("00") + dt.Minute.ToString("00");
        }
        catch (Exception ex)
        {
            return "Enter Correct Format like <5.12 pm>";
        }

    }


    private void button2_Click(object sender, EventArgs e)
    {
       label2.Text = ConvDate_as_date(textBox2.Text);
    }

    public string ConvDate_as_date(string stringFormat)
    {
        try
        {
            string hour = stringFormat.Substring(0, 2);
            string min = stringFormat.Substring(2, 2);
            DateTime dt = new DateTime();
            dt = Convert.ToDateTime(hour+":"+min);
            return String.Format("{0:t}", dt); ;
        }
        catch (Exception ex)
        {
            return "Please Enter Correct format like <0559>";
        }
    }
} }
