关闭页面时出现菜单错误 [英] Menu Error on closing a page

问题描述

我试过使用silverlight菜单，它很棒.关闭通过单击菜单项调用的页面时出现问题.当我关闭页面时，出现错误消息已经添加了具有相同键的项目"，它源自menu.cs第521行(menuDictionary.Add(parentMenuItem.Name，parentMenuItem);)

i have tried using silverlight menu, its great. I have a problem when closing a page i had invoked by cliking a menu item. When i close the page i get an error that says "An item with the same key has already been added" and it originates from menu.cs line 521 ( menuDictionary.Add(parentMenuItem.Name, parentMenuItem);)
Any help would be appreciated.

推荐答案

menuDictionary.Add(parentMenuItem.Name，parentMenuItem);
已经添加了具有相同键的项目"
错误是不言自明的.您有重复的" parentMenuItem.Name "，或者添加了两次.

您有一个字典，其中存储键值对.错误表明您正在尝试重新添加密钥.在字典中，您不能在字典中添加重复键.
阅读: MSDN:Dictionary(Of TKey，TValue)类 [

menuDictionary.Add(parentMenuItem.Name, parentMenuItem);
An item with the same key has already been added"
Error is self explanatory. Either you have duplicate ''parentMenuItem.Name'' or you are adding it twice.

You have a dictionary where key-value pairs are stored. Error tells that you are trying to re-add a key. In dictionary you can not add duplicate key to the dictionary.
