WPF DataGrid未绑定到自定义类型属性

Question

I have a type that looks something like this:

public struct LogData
{
    public DateTime Time;
    public string Area;
    public string Message;
}

In my data context (MVVM) I have an ObservableCollection<LogData> exposed as Log .

For some reason I can't get any of the field data (Time, Area, Message) to show up. The rows properly appear when they are logged but the values in the data grid are blank.

<DataGrid AutoGenerateColumns="False" ItemsSource="{Binding Log}" SelectionMode="Single" CanUserSortColumns="True">
  <DataGrid.Columns>
    <DataGridTextColumn Header="Time" Binding="{Binding Time}" IsReadOnly="True" />
    <DataGridTextColumn Header="Area" Binding="{Binding Area}" IsReadOnly="True" />
    <DataGridTextColumn Header="Message" Binding="{Binding Message}" IsReadOnly="True" />
  </DataGrid.Columns>
</DataGrid>

Any idea why the fields appear blank?

您只能绑定到公共属性（请参阅绑定源概述中的 其他特征 ），例如

public DateTime Time { get; set; }
