.net - .NET WPF XAML“BindingExpression路径错误：...未找到属性”

我试图将我的W3CError类型对象的集合绑定到WPF ListView控件。

这是一个很好的小13线课......

Class W3CError

    Public Type As ErrorOrWarning
    Public Line As Integer
    Public Col As Integer
    Public Message As String
    Public MessageId As String
    Public Explanation As String
    Public Source As String

    Enum ErrorOrWarning
        ValidationError
        ValidationWarning
    End Enum

End Class

它不起作用。我在Visual Studio的“输出”窗口中遇到了这些绑定错误：

System.Windows.Data错误：39： BindingExpression路径错误：'Line' 在'对象'上找不到的属性 ''W3CError'（HashCode = ...）'。 BindingExpression：路径=行; 的DataItem = 'W3CError' （的HashCode = ...）;目标元素是 'TextBlock'（Name =''）;目标财产是'文字'（类型'字符串'）

嗯，不，那不是财产。它只是公共的。我想这对WPF绑定来说还不够好？

我通过将我的班级延长到丑陋的69行属性样板来实现它......

Class W3CError

    Private _Type As ErrorOrWarning
    Private _Line As Integer
    Private _Col As Integer
    Private _Message As String
    Private _MessageId As String
    Private _Explanation As String
    Private _Source As String

    Enum ErrorOrWarning
        ValidationError
        ValidationWarning
    End Enum

    Public Property Type() As ErrorOrWarning
        Get
            Return _Type
        End Get
        Set(ByVal value As ErrorOrWarning)
            _Type = value
        End Set
    End Property

    Public Property Line() As Integer
        Get
            Return _Line
        End Get
        Set(ByVal value As Integer)
            _Line = value
        End Set
    End Property

    Public Property Col() As Integer
        Get
            Return _Col
        End Get
        Set(ByVal value As Integer)
            _Col = value
        End Set
    End Property

    Public Property Message() As String
        Get
            Return _Message
        End Get
        Set(ByVal value As String)
            _Message = value
        End Set
    End Property

    Public Property MessageId() As String
        Get
            Return _MessageId
        End Get
        Set(ByVal value As String)
            _MessageId = value
        End Set
    End Property

    Public Property Explanation() As String
        Get
            Return _Explanation
        End Get
        Set(ByVal value As String)
            _Explanation = value
        End Set
    End Property

    Public Property Source() As String
        Get
            Return _Source
        End Get
        Set(ByVal value As String)
            _Source = value
        End Set
    End Property

End Class

有更好的方法吗？
