Asp.net DateTime formatting Strings issues are very common in day to day development of applications.Dot net made life simple. There are two ways you can set the DateTime formats specific to culture.Let's see how to deal with DateTime in C#.net and Vb.net.After reading this post you will get an idea about how to deal with DateTime issues with website and multi culture.

DateTime in [C#]

The culture and UICulture properties can be set using internet standard string like.
1. en-US where en stands for English and US stands for United States.
2. en-GB where en stands for English and GB stands for Great Britain.
3. es-MX where es stands for Spanish and MX stands for Mexican.

1. CurrentCulture.
2. CurrentUICulture.

DateTime default culture in (.net)

The default culture of .net is en-US, if operating system uses en-US as a language. In US the date time format is MM-DD-YYYY. This is obvious that when you install windows operating system it shows dates in US date time formats. The term CurrentCulture is specific to entire application and available for its life time.

All threads generated by those applications will use Current Culture Information unless and until you change it to use UI specific culture information.

DateTime Example.

For example. Suppose you are Maharashtrian and you speak Marathi language since childhood, you went to another part of region/country where their culture is English. What you will do? Answer is you will start speaking in English if you know it. Same way some part of application can be rendered in many languages with the help of CurrentUICulture.

In previous example Marathi is your mother tongue the base language and others are just culture specific. Same way we can keep the main culture as CurrentCulture and sub culture as UICulture. In Asp.net you can set UI Culture information like this.

In Web.Config or App.Config
 

You can also change the Culture information by referring below codes.We need to use below namespaces.

C#.net DateTime culture

1.
using  System.Threading;
using  System.Globalization;
protected void Button1_Click(object sender, EventArgs e)
{        
Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");
FromDate.Text = DateTime.Now.ToShortDateString();
}
OutPut:
The output Date is “8/4/2011” which is in US MM/DD/YYYY format
2.
protected void Button1_Click(object sender, EventArgs e)    
{        
Thread.CurrentThread.CurrentCulture = new CultureInfo("en-GB");           
FromDate.Text = DateTime.Now.ToString();      
} 
OutPut:
Date and Time is “04/08/2011 19:52:38” which is in UK date and time format DD/ MM /YYYY.
protected void Button1_Click(object sender, EventArgs e)    
{        
Thread.CurrentThread.CurrentCulture = new CultureInfo("sv-SE");         
FromDate.Text = DateTime.Now.ToString();     
} 

Add culture information to (Asp.net) Page

You can also set Page specific culture information by adding UICulture and Culture attributes in Asp.net page as shown in below Example.

By adding UICulture attribute inside page 
<%@ Page UICulture="en" Culture="en-US" %> 

1. If you want to set default DateTime of web Application in specified language, use CurrentCulture.
2. The page specific date and time can be specified using CurrentUICulture. You can also see the complete list of available language support at below link. http://msdn.microsoft.com/en-us/goglobal/bb896001.
