Answer 1

To select a whole new culture, set the CurrentThread.CurrentCulture to a new culture, e.g. to set to French:

System.Globalization.CultureInfo ci = new System.Globalization.CultureInfo("fr-FR");
System.Threading.Thread.CurrentThread.CurrentCulture = ci;

You can find a list of the predefined CultureInfo names here and here.

If you want to change certain aspects of the default culture, you can grab the current thread's culture, use it it's name to create a new CultureInfo instance and set the thread's new culture with some changes, e.g. to change the current culture to use the 'Euro' symbol:

System.Globalization.CultureInfo ci = new System.Globalization.CultureInfo( System.Threading.Thread.CurrentThread.CurrentCulture.Name);
ci.NumberFormat.CurrencySymbol = "€";
System.Threading.Thread.CurrentThread.CurrentCulture = ci;

For some situations it is also necessary to set System.Threading.Thread.CurrentThread.CurrentUICulture. (Note the "UI" in the middle of the property name.) – Aubin

I had to set the UICulture also while running unit tests. Comment above saved me :) – Bloodshot

Answer 2

Thread.CurrentThread.CurrentCulture = yournewculture;

Also see the CurrentUICulture property.

In load Event insert the code below:

      InputLanguage.FromCulture(new System.Globalization.CultureInfo("fa-IR"));

In addition, if you want to refresh all the controls' resources at runtime, you will need to use something like this:

private void RefreshResources(Control ctrl, ComponentResourceManager res)
{
    ctrl.SuspendLayout();
    res.ApplyResources(ctrl, ctrl.Name, CurrentLocale);
    foreach (Control control in ctrl.Controls)
        RefreshResources(control, res); // recursion
    ctrl.ResumeLayout(false);
}

Answer 5

This statements were helpful for me:

string myLanguage = "HE-IL";
InputLanguage.CurrentInputLanguage =
   InputLanguage.FromCulture(new System.Globalization.CultureInfo(myLanguage));
