我熟悉了 WinForms,我正在尝试学习一些 WPF 的东西。
当窗口正在初始化时,我遇到了这个 XAML 解析异常。这是我到目前为止所做的一些调查。
首先,我有 2 个名为“问题”和“答案”的课程。
当我尝试像这样初始化这两个类时出现错误:
public MainWindow()
{
InitializeComponent();
}
private string _firstName;
public string FirstName
{
get { return _firstName; }
set { _firstName = value; }
}
Question _question = new Question();
Answer _answer = new Answer();
private void MetroWindow_Initialized_1(object sender, EventArgs e)
{
}
private void MetroWindow_Loaded_1(object sender, RoutedEventArgs e)
{
//some code here
}
private void btnStart_Click(object sender, RoutedEventArgs e)
{
//some code here
}
但是当我尝试删除问答的初始化时,它运行正常。
顺便说一句,我正在使用 MahApps。
有人可以给我一个提示我的问题吗?非常感谢!

它说
The invocation of the constructor on type 'Recitation_Game.MainWindow' that matches the specified binding constraints threw an exception.' Line number '4' and line position '9
