任何人都会帮助我。提前致谢帕。

Answer 1

我无法确定它，这是一个几乎没有说太多的通用信息。

以下是我要做的事情：

评论所有内容，以便留下<PhoneApplicationPage ...>
注释掉所有依赖于您刚刚注释掉的XAML的C＃代码
确保应用程序已编译。
现在慢慢地，一步一步地重新添加xaml元素。直到找到有问题的行。

如果4.太难了你可以扭转这个伎俩;逐个评论 out 。

Answer 2

你的PhoneApplicationPage_Loaded方法是什么？

除了缺少结束标记

   </phone:PhoneApplicationPage>

在上面的代码片段中，我能够在WP7 7.1中构建并运行它。我确实必须省略你的Loaded和MouseLeftButtonUp引用，因为我没有你的完整代码。
