asp.net中的应用程序本地化

Question

I am close to end of my ASP.net project, and now I am approaching to part where i need to translate my application.

My idea is to keep ID of control in my database table, on a page load I am simply taking "LanguageID" from Session variable that I stored earlier and make simply query to Database and end up with DataTable that looks like

ControlID     |     Text
--------------------------------
tabAutoMail   | E-MAIL PATTERN
tabUser       | LOG IN
lblSignIn     | Please sign in
lblinputEmail | Email address

But my problem here now is that, I don't know how to start next ... if i go with something like this

foreach (Control ctrl in Page.Controls)
{
    foreach (DataRow item in StaticTranslate.Rows)
    {
        if (ctrl.ID == item[0].ToString())
        {

        }
    }
}

Control doesn't have property of "Text", so I can't manually set it, if I go with something like this

foreach (DataRow item in StaticTranslate.Rows)
{ 
    var Test = this.Page.FindControl(item[0].ToString());
}

Again I end up with same problem, I don't know type of control and I can't cast "test" to proper control type

Can you please advice how to approach from here? Thank you

As mentioned in the comments there are other ways of making translations work

If you want to make this work what you need to 2 is to store 3 properties

1. The control name
2. the property you want to localize
3. the localized value

(and of course the language selection needs to be stored somehow/somewhere)

The reason being is that some controls can have localizations in other ways than just 'Text'. (I might want to localize an image source for example, or the maxlength of a postal code textbox can be language/country dependent)

To set a property you then might use code like this.

foreach (DataRow item in StaticTranslate.Rows)
{ 
    var control = this.Page.FindControl(item["ControlName"].ToString());
    var property = control .GetType().GetProperty(item["PropertyName"].ToString());
    property.SetValue(control, item["LocalizedValue"].ToString());
}

This only deals with string localizations now and if i did want to localize the maxlength then i'd need some more work.

I hope this convinced you to go the route NGPixel suggested and use a DB as a provider. If that's too complicated you could even allow your resx file to be updated shown here https://msdn.microsoft.com/en-us/library/gg418542(v=vs.110).aspx That way you could develop an admit tool to update your resx file and the rest of your site using 'standard' localization independently
