如果 DataContext 是您的viewmodel（CLoggerViewModel），则Itemssource绑定应为：

if the DataContext is your viewmodel (CLoggerViewModel) then the Itemssource binding should be:

  <ListView ItemsSource="{Binding LogEntries}" Margin="5,5,5,5" Grid.Column="1" Grid.Row="0">

并且您的LogEntry的绑定表达式应该只是{Binding LogEntry}

and the binding expression to your LogEntry should simply be {Binding LogEntry}

  <GridViewColumn Header="Log Entry"  DisplayMemberBinding="{Binding Path=LogEntry}"/>

编辑：

• 在XAML中忘记智能感知！


• 您的ListView ItemsSource必须绑定到Viewmodel中的Property LogEntries CLoggerViewModel


• GridViewColumn DisplayMemberBinding必须绑定到您的类CLogEntry中的Property LogEntry

DataContext ={Binding LoggerViewModel - >那是什么？这意味着您需要在当前的Datacontext上使用名为LoggerViewModel的公共属性。我不认为这是你想要的。您的Viewmodel代码看起来不错，但问题是您的XAML和设置您的Datacontext。所以请发布您设置DataContext的代码。

DataContext ="{Binding LoggerViewModel}" --> What is that? this means you need a public property called LoggerViewModel on your current Datacontext. i dont think thats what you want. your Viewmodel code looks ok, but the problem is your XAML and setting your Datacontext. so pls post the code where you set the DataContext.
