namespace MMI_WFA 
{ public partial class MainWindow : Form { public int Language { get; set; } ... ... } public partial class MENU : Form { private readonly MainWindow window; public MENU(MainWindow window) { this.window = window; } private void cbo_Language_SelectedIndexChanged(object sender, EventArgs e) { this.window.Language = // } }

}
