In .NET there is the `CultureInfo` class in the `System.Globalization` namespace. It has two similar properties both returning values of the `CultureInfo` type: `CurrentCulture` and `CurrentUICulture`.

What is the difference between them? 

Which one should I use when and why?

What is the difference between CurrentCulture and CurrentUICulture properties of CultureInfo in .NET?

In our application, we receive text files (`.txt`, `.csv`, etc.) from diverse sources. When reading, these files sometimes contain garbage, because the files where created in a different/unknown codepage.

Is there a way to (automatically) detect the codepage of a text file? 

The `detectEncodingFromByteOrderMarks`, on the `StreamReader` constructor, works for `UTF8`  and other unicode marked files, but I&#39;m looking for a way to detect code pages, like `ibm850`, `windows1252`. 

----------

Thanks for your answers, this is what I&#39;ve done.

The files we receive are from end-users, they do not have a clue about codepages. The receivers are also end-users, by now this is what they know about codepages: Codepages exist, and are annoying.

**Solution:** 

  - Open the received file in Notepad, look at a garbled piece of text. If somebody is called Fran&#231;ois or something, with your human intelligence you can guess this.
  - I&#39;ve created a small app that the user can use to open the file with, and enter a text that user knows it will appear in the file, when the correct codepage is used. 
  - Loop through all codepages, and display the ones that give a solution with the user provided text. 
  - If more as one codepage pops up, ask the user to specify more text.


How can I detect the encoding/codepage of a text file

Could anybody give an example to demonstrate the usage of the [**Invariant Culture**](https://msdn.microsoft.com/en-us/library/system.globalization.cultureinfo.invariantculture.aspx)? I don&#39;t understand what the documentation describes.

I&#39;m a member of a team with more than 20 developers. Each developer works on a separate module (something near 10 modules). In each module we might have at least 50 CRUD forms, which means that we currently have near 500 **add buttons**, **save buttons**, **edit buttons**, etc.

However, because we want to globalized our application, we need to be able to translate texts in our application. For example, everywhere, the word **add** should become **ajouter** for French users.

What we&#39;ve done till now, is that for each view in UI or Presentation Layer, we have a dictionary of key/value pairs of translations. Then while rendering the view, we translate required texts and strings using this dictionary. However, this approach, we&#39;ve come to have something near 500 **add** in 500 dictionaries. This means that we&#39;ve breached DRY principal.

On the other hand, if we centralize common strings, like putting **add** in one place, and ask developers to use it everywhere, we encounter the problem of not being sure if a string is already defined in the centralized dictionary or not.

One other options might be to have no translation dictionary and use online translation services like Google Translate, Bing Translator, etc.

Another problem that we&#39;ve encountered is that some developers under the stress of delivering the project on-time can&#39;t remember the **translation keys**. For example, for the text of the add button, a developer has used **add** while another developer has used **new**, etc.

What is the best practice, or most well-known method for globalization and localization of string resources of an application?

What would be best practice to localize your ASP.NET MVC application?

I would like to cover two situations:

  - one application deployment in IIS which would handle multiple languages
  - one language/application deployment.

In first situation should you go with some kind of view based thing like, ~/View/EN, ~/View/FI, ~/View/SWE or something different?

What about second case, just application based config via Web.config and point these different languages to different URLs?

I expect the column to be a VARCHAR2, in my Oracle Database.

US Zips are 9.

Canadian is 7.

I am thinking 32 characters would be reasonable upper limit

What am I missing?


[EDIT]
TIL: 12 is a reasonable answer to the question

One of the fun parts of multi-cultural programming is number formats.

- Americans use 10,000.50
- Germans use 10.000,50
-  French use 10 000,50

My first approach would be to take the string, parse it backwards until I encounter a separator and use this as my decimal separator. There is an obvious flaw with that: 10.000 would be interpreted as 10.

Another approach: if the string contains 2 different non-numeric characters, use the last one as the decimal separator and discard the others. If I only have one, check if it occurs more than once and discards it if it does. If it only appears once, check if it has 3 digits after it. If yes, discard it, otherwise, use it as decimal separator.

The obvious &quot;best solution&quot; would be to detect the User&#39;s culture or Browser, but that does not work if you have a Frenchman using an en-US Windows/Browser.

Does the .net Framework contain some mythical black magic floating point parser that is better than `Double.(Try)Parse()` in trying to auto-detect the number format?

I18n/L10n/G11n all equal localization to me, but people keep making distinctions among these, especially in corporate and marketing, but I&#39;m failing to see how these 3 tasks, from the programmer&#39;s point of view aren&#39;t the same thing, are there special requirements behind each one of these? What is some honest programmer to programmer explanations of these terms that doesn&#39;t involve global markets, in other words what&#39;s the nitty-gritty differences behind these three terms, when translated to developing (coding) software?

In Denmark, we use the notation 19,95 instead of the US way 19.95 when we write a price for at product, and that have given me a problem, that I can&#39;t solve.

I&#39;ve started VS2010, new MVC 3 project, added a homeController, a Product class, and a simple standard edit view and the error is already there.

**Product Class:**

    public class Product
    {
        public string name { get; set; }
        public string itemNo { get; set; }
        public decimal price { get; set; }
    }


**HomeController:**

    public class homeController : Controller
    {
        public ActionResult Index()
        {
            var product1 = new Product { name = &quot;Testproduct&quot;, itemNo = &quot;PRD-151541&quot;, price = 19 };
            return View(product1);
        }
    }

**Index View:**

    @model WebUI.DomainModel.Product

    &lt;script src=&quot;@Url.Content(&quot;~/Scripts/jquery.validate.min.js&quot;)&quot; type=&quot;text/javascript&quot;&gt;&lt;/script&gt;

                @Html.LabelFor(model =&gt; model.name)
            &lt;/div&gt;

                @Html.ValidationMessageFor(model =&gt; model.name)
            &lt;/div&gt;
    
            &lt;div class=&quot;editor-label&quot;&gt;
                @Html.LabelFor(model =&gt; model.itemNo)

            &lt;div class=&quot;editor-label&quot;&gt;
                @Html.LabelFor(model =&gt; model.price)
            &lt;/div&gt;
            &lt;div class=&quot;editor-field&quot;&gt;
                @Html.EditorFor(model =&gt; model.price)
                @Html.ValidationMessageFor(model =&gt; model.price)
            &lt;/div&gt;

Is there a way to format the correct currency representation for a country?

Example
UK	-&#163;127.54
Netherlands	€ 127,54-
USA $127.54

etc..


Some things to consider,

 1. Currency Symbol

 2. Currency symbol placement -- It can
    be either place before or after the
    digits.

 3. Negative-amount display

I have to detect decimal separator in current windows setting. Im using visual studio 2010, windows form. In particular, if DecimalSeparator is comma, if user input dot in textbox1,  I need show zero in textbox2.


I tryed with this code, but not works:

    private void tbxDaConvertire_KeyPress(object sender, KeyPressEventArgs e)
        {
            string uiSep = CultureInfo.CurrentUICulture.NumberFormat.NumberDecimalSeparator;
            if (uiSep.Equals(&quot;,&quot;))
            {
                while (e.KeyChar == (char)46)
                {
                    tbxConvertito.Text = &quot;0&quot;;
                }
            } 
        }

I have tryed also this code, but not work:

In .NET is there any way to convert from three letter country codes (defined in ISO 3166-1 alpha-3) to two letter language codes (defined in ISO 3166-1 alpha-2)  eg. convert BEL to BE? 

Have looked at the RegionInfo class in System.Globalization but the constructor does not seem to support the three letter codes.
