Ease of applying Globalization and Localization with 2.0

I had previously written, an article explaining Localization and Globalization concept in 1.3, but with 2.0 the same generalize concept of localization and globalization can be implemented more easily.

I would suggest reader to read the previous article which help you to identify the ease of applying the concept.

Understanding concept with Example
Step1: Create a Web Project.

Step2: Design your form.
For this example : Take 5 label controls, 4 textbox controls and 1 drop-down list control.
Place the control on form as shown in figure.

Step3: Identifying Resources that needs to be localized (Globalization Phase).
We want the output as shown in figure:

So here Resource that needs localization are

Language Name Label
Long Date Label
currency Label
Amount Label
Welcome Label (It would be same for all language, except its formatting might change, Note: you can do this easily with style-sheet concept, but as an example here I am explaining it with globalization concept.)

Now, Applying Localization to resources which needs to be localized and globalization phase. (Localization Phase begin).

Step5: Creating Resource File.
For this example i am creating resource file for French and German culture and other culture would get value from default resource file. Right click the Project in Solution Explorer and add a “ folder”

Add App_GlobalResources Folder Add App_LocalResources Folder

Adding Global Resource File under App_GlobalResources Folder

Adding Local Resource File under App_LocalResources Folder

Note: While creating resource file, you should name resource file with filename.aspx.cultercode.resx

1 For Default.aspx file, Default resource file would be Default.aspx.resx

2 For German resource file for Default.aspx would be

3 For French resource file for Default.aspx would be

Step6: Adding code in .CS file to make it work

Adding Namespace
using System.Globalization;
using System.Drawing;
using System.Threading;

Filling Dropdown with set of languages for user-choice.
Code in Page Load Event.

//Applying Globalization to Header Text
lblWelcome.Text = Resources.GlobalResource.HeaderTitleText; lblWelcome.ForeColor = Color.FromName(Resources.GlobalResource.HeaderTitleColor);
//CultureInfo Class GetCultures gives collection of language.
foreach(CultureInfo ci in CultureInfo.GetCultures(CultureTypes.SpecificCultures))
//Filling the language collection into drop-downlistbox for user choice.
ddlLanguage.Items.Add(new ListItem(ci.EnglishName,ci.Name));
//Calling the Event when page loads for the first time.

Assigning selected language value to current thread, to reflect changes.
private void ddlLanguage_SelectedIndexChanged(object sender, System.EventArgs e)
Thread.CurrentThread.CurrentUICulture = new CultureInfo(ddlLanguage.SelectedValue);
Thread.CurrentThread.CurrentCulture = new CultureInfo(ddlLanguage.SelectedValue);

//Applying Localization

Code which requires localization value.
private void ApplyUILocalization()
lblLanguageName.Text = Convert.ToString( this.GetLocalResourceObject("LanguageName"));
lblLongDate.Text = Convert.ToString( this.GetLocalResourceObject("LongDate"));
lblCurrency.Text = Convert.ToString( this.GetLocalResourceObject("Currency"));
lblAmount.Text = Convert.ToString( this.GetLocalResourceObject("Amount"));

Code which does not requires localization.
private void ApplyLocalization()
//Lets Assume currency and amount to keep example simple.
double dblCurrency = 500.50;
double dblAmount = 9580000.75;

//No extra effort for localization as you see here.
txtLanguageName.Text = ddlLanguage.SelectedItem.Text;
txtLongDate.Text = DateTime.Now.ToLongDateString();
txtCurrency.Text = dblCurrency.ToString("c");
txtAmount.Text = dblAmount.ToString("n");

Now, run the application and select the different culture and based on selection you will get the localized display as shown in figure:

When associated resource file not available culture from Default Resource File would be shown.

how simplest syntax structure is used to perform globalization and localization.

This is very GoodExample .
i understood very easly.
please give example on changing the text with different languages.

Localization and Globalization concept applies to resources (like display labels, etc) and upto certain extent to data, like currency, date format, digit seperator and so... unfortunately you cannot change text data feed in by user automatically as language chages, (On base of recent event attended by me, i come to know that in future microsoft will be going to add this feature to OS, wherein you have liberty to change data as you change language).

I am developer

Good Example for Localization, Thanks.

This is very good example, i understood very easily....but u said ApplyLocalization()and ApplyUILocalization() are localization. these functions are behaving differently at different cultures, so this is not localization, it is globalization..and lblWelcome label is also not globalization,it is not behaving differently at different places, so it is please change it..thanq
