c＃如何将事件处理程序添加到foreach循环中的许多菜单？

Question

I'm working with the compact framework and i'm making an app for a windows mobile standard. I have an array which contain phonenumbers, and i want to add a submenu foreach number i find in that array. These submenus must be clickable, but i can't figure out how to do it.

This is my code:

             // "menuItemRight" is my main menu


             // Send a message to the person
            MenuItem smsMenu = new MenuItem();
            smsMenu.Text = "Melding";
            menuItemRight.MenuItems.Add(smsMenu);

   foreach (string Number in aPhoneNumbers)
            {
                MenuItem mNumber  = new MenuItem();

                string sNumber = Number.Trim();
                mNumber.Text = sNumber.Trim();


                //SMS
                mSMS.Text = sNumber.Trim();
                smsMenu.MenuItems.Add(mSMS);
                //mNumber.Click += new EventHandler(this.MenuClick);
            }

So what i want is a common eventhandler, but i don't know how to implement this.

Hope someone can help me :)

Thanks in advance

Answer 1

when the function MenuClick is called it recieves an object arg (object sender) which is the MenuItem clicked.

to have the number in this function :

string sNumber = ((MenuItem)sender).Text;
...

because you stored it in the foreach loop in that property:

mNumber.Text = sNumber.Trim();
...

Answer 2

Set up your event handler so it takes the phone number (or whatever data you want to pass across) as the event arguments. You'll have to derive a new event arg based class.

Thus you have one handler in which you unpack the event args to find out which item you're dealing with.

Answer 3

The constructor for MenuItem has what you are after ( onClick )

You can modify your loop code slightly to put some identifier into each items .Tag property, and then in your event handler, cast the sender parameter back to a MenuItem .
