Preparing for internationalization of asp net mvc website


Internationalization is the process of designing and developing software that can be adapted to different languages and cultures. In the context of ASP.NET MVC websites, internationalization refers to making the website accessible and user- for from different regions and languages.

Setting the Culture and UI Culture

One of the first steps in an ASP.NET MVC website for internationalization is to set the culture and UI culture of the application. The culture determines the formatting of dates, numbers, and currencies, while the UI culture determines the and localization of the user interface.

To set the culture and UI culture in ASP.NET MVC, you can use the Thread.CurrentThread.CurrentCulture and Thread.CurrentThread.CurrentUICulture properties. These properties can be set in the Application_BeginRequest method in the Global.asax.cs file:

protected void Application_BeginRequest()
    string culture = "en-US"; // default culture
    string uiCulture = "en-US"; // default UI culture

    // Check if the user has  a different culture
    if (Request.Cookies["Culture"] != null)
        culture = Request.Cookies["Culture"].Value;
        uiCulture = Request.Cookies["Culture"].Value;

    // Set the culture and UI culture
    Thread.CurrentThread.CurrentCulture = new CultureInfo(culture);
    Thread.CurrentThread.CurrentUICulture = new CultureInfo(uiCulture);

In this example, the default culture and UI culture are set to “en-US”. However, if the user has selected a different culture, the values are retrieved from a cookie and set accordingly.

Resource for Localization

Localization involves translating the text and resources used in the website into different languages. ASP.NET MVC provides a mechanism for managing localized resources using resource files.

To create a resource file, right-click on the project in Visual Studio, select “Add” > “New Item”, and choose “Resource File”. Give the file a name, such as “Resources.resx”. This file will serve as the default resource file for the website.

To add localized resources, right-click on the resource file, select “Add” > “New Item”, and choose “Resource File” again. This time, give the file a name that includes the culture code, such as “” for French (France).

Once the resource files are created, you can add key-value pairs for each localized string. For example, you can add a key “WelcomeMessage” with the value “Welcome to our website!” in the default resource file, and provide translations for this key in the localized resource files.

Using Localized Resources in Views

To use the localized resources in views, you can use the Resources class by ASP.NET MVC. This class provides access to the localized strings defined in the resource files.

For example, if you have a view that a welcome message, you can use the following code to the localized string:


This code will display the appropriate localized string based on the current culture and UI culture of the application.


Preparing an ASP.NET MVC website for internationalization involves setting the culture and UI culture, managing localized resources using resource files, and using the Resources class to access the localized strings in views. By following these steps, you can create a website that can be easily adapted to different languages and cultures, providing a better user experience for international users.
