This article explains how to make a multilingual application.
About the Sample Project
The sample project given in this article is an example of a Multilingual application. When speaking about multilingual applications, we need to manage resources specific to each culture. In my sample project, I have supported 5 languages, English, German, Spanish, Italian and French. This sample project supports switching to any of five languages at runtime.
It is very simple to make a multilingual application in C#. I used Visual Studio .NET 2003 to create my sample application. There is also a free IDE known as SharpDevelop which looks similar to Visual Studio .NET.
Now the Steps
- Do everything with the
FormLayout (I mean design of your application).
- After the Designing of the form is done, the form now uses the default Language setting. Now build the application.
- Change the forms properties
true and set the properties
Language to whatever Language you like to use.
- Change the Text of the
Form and so on.. to the Language you have selected (isn't Limited only for
Text property, you can also change layout specific to
- Build the application.
- We are done now. Repeat steps 3 to 5 for the next language you wish to localize.
Now we have done something, but how do we check this work. We have to do something with the code.
The above code specifies the
Currentuiculture for your application. This code has to be executed before initialization of the components. The
string given inside the
CultureInfo constructor ("
de") specifies the language name for the culture. Some of the culture names and languages are given below:
en - English
de - German
fr - French
it - Italian
es - Spanish
pt - Portuguese
How Does This Work
This section is the important one. When we set the form's localizable to true and build the application, Visual Studio .NET creates resources specific to the culture specified in the
Language property of the form. Visual Studio .NET creates the resource file using resgen.exe. We can also create resources by using the following syntax:
resgen mytext.en-us.txt mytext.en-us.resources
resgen mytext.en-us.resources mytext.en-us.resx
Now the resources are created, but we need to link them to the application, so this is done by Visual Studio .NET using AL.exe (Assembly linker). We can also do it manually by doing this:
You can find more about resgen.exe and al.exe in MSDN documentation.
