在Windows Phone7中，我創建了一個UserControl，我正在解析一些數據。現在我無法制作該Usercontrol的實例。Usercontrol無法創建實例[XapCannotFindFileInPackage]
當我刪除從用戶控件解析我能夠做的實例，除非我收到錯誤，如
`"Cannot create instance of '<usercontrolname>'
"XapCannotFindFileInPackage]
Arguments:HelpScreenData.xml
Debugging Resource String are unavailable.Often the key and
arguments provide sufficient information to diagonise the problem.see
http://go.microsoft.com'/fwlink/?linkid=106663&version5.0.10411.00&
file=system.xml.dll&key=Xml_cannot find file in Xappackage"
我的用戶控件代碼隱藏

是解析
XML的樣本<?xml version="1.0" encoding="utf-8" ?>
<plist version="1.0">

<row>

<string>Answer your client’s difficult .</string>
</row>

你知道哈利波特嗎？他發現了一個神奇的詞，可以幫助猜測你的控制是如何編碼的。不幸的是，他沒有在stackoverflow上註冊。尚未 – 2012-07-31 13:40:42
abracadabra！哪一行導致此問題？用//解析的那個？如果是，那麼xml文件的內容是什麼？ – 2012-07-31 14:13:23
錯誤不會發生在代碼但是，當我拖n刪除UserControl.Check編輯，我已解析的XML – 2012-07-31 14:23:48
