How to display the current time and date in C#

H开发者_Go百科ow do you display the current date and time in a label in c#

---

You'd need to set the label's text property to DateTime.Now:

labelName.Text = DateTime.Now.ToString();

You can format it in a variety of ways by handing ToString() a format string in the form of "MM/DD/YYYY" and the like. (Google Date-format strings).

---

For time:

label1.Text = DateTime.Now.ToString("HH:mm:ss"); //result 22:11:45

or

label1.Text = DateTime.Now.ToString("hh:mm:ss tt"); //result 11:11:45 PM

For date:

label1.Text = DateTime.Now.ToShortDateString(); //30.5.2012

---

The System.DateTime class has a property called Now, which:

Gets a DateTime object that is set to the current date and time on this computer, expressed as the local time.

You can set the Text property of your label to the current time like this (where myLabel is the name of your label):

myLabel.Text = DateTime.Now.ToString();

---

labelName.Text = DateTime.Now.ToString("dddd , MMM dd yyyy,hh:mm:ss");

Output:

---

If you want to do it in XAML,

xmlns:sys="clr-namespace:System;assembly=mscorlib"
<TextBlock Text="{Binding Source={x:Static sys:DateTime.Now}}"

With some formatting,

<TextBlock Text="{Binding Source={x:Static sys:DateTime.Now},
                  StringFormat='{}{0:dd-MMM-yyyy hh:mm:ss}'}"

---

DateTime.Now.Tostring();

. You can supply parameters to To string function in a lot of ways like given in this link http://www.geekzilla.co.uk/View00FF7904-B510-468C-A2C8-F859AA20581F.htm

This will be a lot useful. If you reside somewhere else than the regular format (MM/dd/yyyy)

use always MM not mm, mm gives minutes and MM gives month.

---

In WPF you'll need to use the Content property instead:

label1.Content = DateTime.Now.ToString();

---

label1.Text = DateTime.Now.ToLongTimeString();//its for current date

label1.Text = DateTime.Now.ToLongDateString();//its for current time
