在Windows Phone7中，我创建了一个UserControl，我正在解析一些数据。现在我无法制作该Usercontrol的实例。Usercontrol无法创建实例[XapCannotFindFileInPackage]
当我删除从用户控件解析我能够做的实例，除非我收到错误，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"

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

你知道哈利波特吗？他发现了一个神奇的词，可以帮助猜测你的控制是如何编码的。不幸的是，他没有在stackoverflow上注册。尚未 – 2012-07-31 13:40:42
abracadabra！哪一行导致此问题？用//解析的那个？如果是，那么xml文件的内容是什么？ – 2012-07-31 14:13:23
错误不会发生在代码但是，当我拖n删除UserControl.Check编辑，我已解析的XML – 2012-07-31 14:23:48
