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;

Thread.CurrentThread.CurrentCulture = yournewculture;

Also see the CurrentUICulture property.

In load Event insert the code below:

InputLanguage.CurrentInputLanguage =
      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);
}

If you want a better example check my blog.

This statements were helpful for me:

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