Correct method to share code to retrieve information

Question

User1883908716 posted

Hi all,

I'm trying to build a multilanguage app with webmatrix. Basically the app will have a default language (eg. 'IT') and the other languages will be selected manually by the user from a link in the menu. Instead of a request, as per mikesdotnetting template code, I would like to extract and filter the content from a database using a "UrlData[0]" string (es. IT,ES,EN,...) avoiding the request into the Url. But I don't know how.

Using the "_StartPage.cshtml" by href I can get a result but not the same that I can have with the post method and it's not that I would like to have because the URL include the request string eg. "?lang=en"

        <a href="~/?lang=iT-it">IT</a>
        <a href="~/?lang=en-en">EN</a>
        <a href="~/?lang=fr-FR">FR</a>
        <a href="~/?lang=de-DE">DE</a>

The Url that I would like to have is in eg.:

http://localhost:54083/  --> Value IT or it-IT

http://localhost:54083/IT/ --> Value IT or it-IT

http://localhost:54083/EN/ --> Value EN or en-GB

...

I tried with Functions* but 1) i don't know if it the correct method, 2) I don't know in deep "how to". here below the last don't working code.

public string UserLang (string Url) {
    var fmylang = "";
                try
                {
                    fmylang = Url;
                    return fmylang;
                }
                catch (WebException ex)
                {
                    fmylang="IT";
                    return fmylang;
                }
}

Can someone help me to find a correct code to check UrlData and manage the information.

Thanks in advance,

Nik

*: To improve myself, where I can found clear and detailed information about functions? eg. when use it, public static..., how call function etc.etc.

Solved using _PageStart:

@using System.Web.Mvc;
@using System.Text;
@using System.Globalization;
@{

var MyLang ="";
    Layout = "~/_SiteLayout.cshtml";
    if(UrlData[0].ToString() =="") {
        PageData["myLang"]= "it-IT";
        PageData["myLangHtml"] ="it";
        Culture = UICulture = "it-IT";
        }
    else {
        var db_lang = Database.Open("StarterSite");
        var flang = UrlData[0];
        var SQLSELECT = "SELECT * FROM SYS_LANG where LANG=@0";
        var Details = db_lang.QuerySingle(SQLSELECT, flang);
        int lCount = 0;
        foreach(var Detail in db_lang.Query(SQLSELECT, flang))
            {
                lCount = lCount + 1;
            }
            if (lCount > 0) {
             PageData["myLang"] = Details.CULTURE_CODE;
             PageData["myLangHtml"] = Details.LANG;
             Culture = UICulture = Details.Culture_Code;  
            } else {
                PageData["myLang"]= "it-IT";
                PageData["myLangHtml"] ="it";
                Culture = UICulture = "it-IT";    
            }
    }
}
