copied!<p>In your C# function, the follow variable <em>exceptionMessage</em> :</p> <pre><code>string exceptionMessage = ResourcesNameSpace.ResourceFileName.strYouMustSelectAValidCategory; </code></pre> <p>can assume the correct value (the spanish or the english text), if you have the key "strYouMustSelectAValidCategory" in both files ResourceFileName.resx and ResourceFileName.en-US.resx.</p> <p>So, you can then write:</p> <pre><code>throw new Exception(exceptionMessage); </code></pre> <p>The application will "know" the current culture in runtime :) </p> <p>To set the current culture in your application, you can use, say, a link button with code-behind:</p> <pre><code>// Changes the CurrentUICulture of the current thread: Thread.CurrentThread.CurrentUICulture = new CultureInfo( "en-US", false ); </code></pre> <p>(source: <a href="http://msdn.microsoft.com/en-us/library/system.globalization.cultureinfo.currentuiculture.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/system.globalization.cultureinfo.currentuiculture.aspx</a>)</p> <hr> <p>To add resource files to the project, you can right click your project icon (ModeloInventario), select "Add New Item", select "Resource file" and type a name for your file (I'm using vs2008, hope it isn't too different!).</p> <p>Your default Resource file can be named: <strong>MIResources.resx</strong> </p> <p>Then, you add another one, and name it: <strong>MIResources.en-US.resx</strong>, for english... <strong>MIResources.fr</strong> for french... And so on, one file for each additional language you would like (Language codes here: <a href="http://msdn.microsoft.com/en-us/library/ms533052%28VS.85%29.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/ms533052%28VS.85%29.aspx</a>).</p> <p>The default resource file is the default place where a value is searched when the item is not present in the current culture resource file or when there is no resource file for the current culture.</p> <p>You then start by adding the keys and values to your default resource file (strYouMustSelectAValidCategory: Debe seleccionarse una Categoría válida.), and then add the same keys to the MIResources.en-US.resx with the transation (strYouMustSelectAValidCategory: You must select a valida category.)... So, same keys, different values.</p> <p>After all this, you can get a key's (string) value anywhere in the application, using:</p> <pre><code>string str = ResourcesNameSpace.MIResources.strYouMustSelectAValidCategory; </code></pre> <p>The ResourcesNameSpace is the namespace that's created with the resource file, if any! You can check it or edit it in the code-behind of the default resource file... If none, you don't need to use it (as long as you get to your MIResources.strYouMustSelectAValidCategory).</p>
