getting overflow exception while intiliazing in c# constructor

i have a class like this 

public class Menu
    {
        public int MenuID { get; set; }
        public string MenuName { get; set; }
        public string LinkAddress { get; set; }
        public Menu[] menu;
}

while i am trying to intilize in the constructor as follows i get an overflow exception error

 public Menu() {
            Menu[] menu = {
                              new Menu { MenuID = 1, MenuName = "Home", LinkAddress = "home/index" } 
                              , new Menu { MenuID = 2, MenuName = "Gallery", LinkAddress = "Gallery/index" } 
                              , new Menu { MenuID = 3, MenuName = "Academics", LinkAddress = "Academics/index" } 
                              , new Menu { MenuID = 4, MenuName = "Blog", LinkAddress = "Blog/index" } 
                              , new Menu { MenuID = 5, MenuName = "Login", LinkAddress = "Login/index" } 
                              , new Menu { MenuID = 6, MenuName = "UserLogin", LinkAddress = "UserLogin/index" } 
                              , new Menu { MenuID = 7, MenuName = "ForgotPassword", LinkAddress = "ForgotPassword/index" } 
                          };
        }

i also tried to intialize myvariable 

public Menu[] menu;

in the constructor but i was not able to intialize it. can anyone tell me what exactly am i doing wrong. I thought constructor is used to intialize variables but i am not able to intiliaze it. thank you for your help.

you are made a circular reference when declaring an array of a class inside the class:

 public Menu[] menu;//<-- declaring inside Menu class produces circular refernce

thus an overflow exception

Use a method instead, e.g:

public void InitMenu()
        {
            this.menu = new Menu[]{
                                new Menu { MenuID = 1, MenuName = "Home", LinkAddress = "home/index" }
                              , new Menu { MenuID = 2, MenuName = "Gallery", LinkAddress = "Gallery/index" }
                              , new Menu { MenuID = 3, MenuName = "Academics", LinkAddress = "Academics/index" }
                              , new Menu { MenuID = 4, MenuName = "Blog", LinkAddress = "Blog/index" }
                              , new Menu { MenuID = 5, MenuName = "Login", LinkAddress = "Login/index" }
                              , new Menu { MenuID = 6, MenuName = "UserLogin", LinkAddress = "UserLogin/index" }
                              , new Menu { MenuID = 7, MenuName = "ForgotPassword", LinkAddress = "ForgotPassword/index" }
                          };
        }

and consume as:

Menu m = new Menu();
            m.InitMenu();
            m.menu=..;//<--acces your array
