What is Localization/Multilingual and  Globalization? The term "Localization" defined as "Process of  translating resources for a specific culture/languages", where "Globalization"  defined "Process of designing applications that can adapt to different  cultures/languages". When we publish a site for different regions then it'll be  great if the site content is displayed in that regional language. SharePoint  provides Language Packs which can be downloaded and installed from Microsoft  Site. but the limitation in this is only the SharePoint site labels/text will be  displayed in selected language and the user defined contents won't be translated  by SharePoint.
How to enable Localization in  SharePoint 2010? Assume we develop a webpart that has a registration  form. A user from German wish to register and he needs the form in German/Dutch  language. Even though Dutch language pack installed and enabled in SharePoint,  the webpart text won't be translated/displayed in German. So how to make webpart  that can adapt different languages. For those working in .Net platform knows it  can be done with Resource files (.resx). Resource files are nothing but  Key/Value Pair defined XML format files.
Here the steps to create a  Webpart that detects the selected language in SharePoint and display contents  that fetched from Resource Files.

1. Open Visual Studio 2010 -> File -> New -> Project       
2. Select [Template] Visual C# -> SharePoint -> 2010 [Framework] .Net   Framework 3.5 [Project] -> Empty SharePoint 2010 Project. Name of the   Project : vsProject     
3. In the SharePoint Customization Wizard, enter the URL of the local site   (http://vsnet/) and select Deploy as a farm solution.     
4. Create Resource Files
   1. Resource files should be present in SharePoint Root "Resources" folder.     In Solution Explorer select project "vsProject", right click and select Add     -> SharePoint Mapped Folder.         
   2. In the Window select "Resources" Folder.         
   3. Now an empty "Resources" folder is created inside SharePoint project.     Any files placed inside this folder will be copied to SharePoint Root     (14)\Resources Folder while deploying.         
   4. Right click on Resources folder and select Add -> New Folder ->     vsProject [Folder Name]. Always create folder and place files. This will     avoid the files getting deleted when any SharePoint service pack     installed.
   5. Right click on Newly created folder [vsProject] and select New -> New     Item.         
   6. In the New Item window select [Template] Visual C# -> General ->     Resources File -> Name the files as "vsProject.resx". This is for default     language which in English (LCID : 1033).         
   7. Select vsProject.resx file, right click and Open.          
   8. Add Name and Value pairs as required.         
   9. Repeat Step "f." and provide name "vsProject.de-DE.resx". This file is     for Dutch language. Refer the end of the article to get full list.         
   10. Open "vsProject.de-DE.resx" and enter the same Name as in vsProject.resx     and provide value in German Language. Here "Comment" Field is optional.         
5. Create Webpart    The Resource file is ready to use and now   need to create Web part that get value from those resource files.     
   1. Right Click on the Project "vsProject" and "Add -> New Item"
   2. Select "Visual C# -> SharePoint -> 2010 -> Web Part". Name :     "LocalizationDemo".         
   3. Copy paste the below code inside LocalizationDemo class or     just refer it. protectedoverridevoid CreateChildControls()             {   int intLCID = System.Threading.Thread.CurrentThread.CurrentUICulture.LCID;       Label lblWelcomeText = newLabel();               lblWelcomeText.Text = "Value : " + getLocalizedValue("WelcomeText", intLCID);       this.Controls.Add(lblWelcomeText);             }
      publicstring     getLocalizedValue(string strInput,     int intLCID)         {   //     Function to retreive specified Language Variation     Value   string strLocalizedValue =     "";
                strLocalizedValue =     Microsoft.SharePoint.Utilities.SPUtility.GetLocalizedString("$Resources:     "     + strInput, "vsProject\\vsProject",     (uint)intLCID);           return     strLocalizedValue;         }         
   4. Save all files, Build and Deploy. The solution will be deployed in     SharePoint and ready to use.         
   5. Open the SharePoint site any page and click "Edit" Icon on top (or Site     Actions -> Edit page).         
   6. Select "Editing Tools [Tab] -> Insert [Tab] -> Web Part ->     Custom [Categories] -> LocalizationDemo -> Add [Button]".         
   7. Once the webpart added to the page select "Save and close"   Icon.
6. Now it'll show the content in default language (English - 1033). Select   "User Menu" at top right and select "Select Display Language ->   Deutsch".
7. The page will be refreshed the Web Part will show the German Content which   specified in the resource file.
