C# 这是我的XAML代码，它有第41行及其位置252

我一直在开发一个Windows Phone应用程序，它将图像和文本一起拍摄并上传到服务器

---

调试应用程序时出现问题。这个问题似乎是技术性的。我真的不知道该怎么办

这就是为什么我想在这里发布这些问题。如果你们中有人能帮助解决这个问题，我将非常感谢你们在这里给我的帮助

我真的很感激这里所做的工作。如果没有你们，我们真的不会走这么远。你给了我们从错误中学习的机会

再次感谢

请检查我的代码是否需要调整

以下是我在Emulator上调试时弹出的错误消息：

未能分配到属性“System.Windows.Controls.Primitives.ButtonBase.Click”。[第41行位置：250]

不幸的是，这是我的第一篇帖子，所以我不能发布图片

我感谢这里所做的工作

    }

这是第41行。。。位置252是“单击=我的按钮3\u单击”

在您提到的所有更改之后，我仍然会遇到三个相同的错误

错误2“System.Windows.RoutedEventArgs”不包含“ChosenPhoto”的定义，并且找不到接受“System.Windows.RoutedEventArgs”类型的第一个参数的扩展方法“ChosenPhoto”（是否缺少using指令或程序集引用？）C:\Users\Yaseen\Desktop\IC Final\Phone Application\MainPage.xaml.cs 107 41 Phone Application

这些直接出现在button3语法之后

我认为您发布的代码与错误消息无关

但你的问题似乎和我一样

---

当codebehind只有

按钮3\u单击时，您将XAML中的单击设置为
myButton3\u单击

这些应该是匹配的。
问题不在您发布的代码中，而在您的XAML中，因此您得到的XAMLParse错误。您可以发布相应XAML的第41行（以及前后几行）。+1是的，
button3\u Click
的签名肯定应该是
RoutedEventArgs e
，而不是
PhotoResult e
。我真的不知道如何解决这个问题。+1，但请将XAML修改为
Button2\u Click
。而且代码背后的签名也不正确。
