数据绑定没有'；不工作XAML C#WPF

我有一个WPF表单，希望将反序列化的json数据绑定到UI上的datagrid。但在这里，我无法在UI上看到数据网格中的值

JSON response:
Firstly, my json response is in the below format:
{
    "results":
        [
           {"type": "upload", "status": "new","data": {"uuid":"f7e98"},"device_id": "123"},
           {"type": "upload", "status": "new","data": {"uuid":"f8fc1"},"device_id": "456"}, 
           {"type": "upload", "status": "new","data": {"uuid":"fgff1"},"device_id": "678"},
           {"type": "upload", "status": "new","data": {"uuid":"yuki1"},"device_id": "786"},
           {"type": "upload", "status": "new","data": {"uuid":"rtyi1"},"device_id": "654"}
        ]
}

课程：

public class UploadStatusList
{
    public List<UploadStatus> results;
}
public class UploadStatus
{
    public string type {get;set;}
    public string status {get;set;}
    public string device_id {get;set;}
    public Data data {get;set;}
}
public class Data
{
    public string uuid {get;set;}
}

public partial class MainWindow : Window
{
    // Dependency Property
    public static readonly DependencyProperty actionListProperty =
        DependencyProperty.Register("actionList", typeof(ObservableCollection<UploadStatusList>),
            typeof(MainWindow), new FrameworkPropertyMetadata(null));

    // .NET Property wrapper
    public ObservableCollection<UploadStatusList> actionList
    {
        get { return (ObservableCollection<UploadStatusList>)GetValue(actionListProperty); }
        set { SetValue(actionListProperty, value); }
    }


    public MainWindow()
    {
        InitializeComponent();
        //Code Block for httpwebRequest here
        //JSON Response String 
        string json = stringbuilder.ToString();

        //Newtonsoft.Json.JsonConvert.Deserialize<UploadStatusList>(json) returns null for me here,so using Javascript serializer. No idea why !? 
        UploadStatusList list = new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<UploadStatusList>(json);
        foreach (var item in list.results)
        {
            Debug.Print("id: {0}, name: {1}", item.status, item.device_id);
        }
    }
}    

<TabItem x:Name="UploadList" Header="Upload List" HorizontalAlignment="Left" Width="77" Margin="-2,-2,0,2">
                <Grid Margin="0,0,0,0">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="124*"/>
                        <ColumnDefinition Width="107*"/>
                    </Grid.ColumnDefinitions>


                    <Button x:Name="Button" Content="Refresh" Margin="14,40,0,361" HorizontalAlignment="Left" Width="120" Click="Button_Click"/>

                    <DataGrid Margin="14,79,10,58" x:Name="Access_DataGrid" IsReadOnly="True" ItemsSource="{Binding actionList.results}" IsSynchronizedWithCurrentItem="True" AutoGenerateColumns="False">
          <DataGrid.Columns>
              <DataGridTextColumn Header="status" Binding="{Binding status}" />
              <DataGridTextColumn Header="device id" Binding="{Binding device_id}" />
              <DataGridTextColumn Header="type" Binding="{Binding type}" />
           </DataGrid.Columns>

                    </DataGrid>
                </Grid>
            </TabItem>

公共类上传状态列表
{
公开名单结果；
}
公共类上载状态
{
公共字符串类型{get；set；}
公共字符串状态{get；set；}
公共字符串设备\u id{get；set；}
公共数据数据{get；set；}
}
公共类数据
{
公共字符串uuid{get；set；}
}

这是我的主窗口。xaml.cs
MainWindow.xaml.cs:

    public string status {get;set;}
    public string device_id {get;set;}
    public Data data {get;set;}

}

public partial class MainWindow : Window

    public static readonly DependencyProperty actionListProperty =
        DependencyProperty.Register("actionList", typeof(ObservableCollection<UploadStatusList>),
            typeof(MainWindow), new FrameworkPropertyMetadata(null));

    // .NET Property wrapper
    public ObservableCollection<UploadStatusList> actionList
    {
        get { return (ObservableCollection<UploadStatusList>)GetValue(actionListProperty); }
        set { SetValue(actionListProperty, value); }
    }


    public MainWindow()
    {
        InitializeComponent();
        //Code Block for httpwebRequest here
        //JSON Response String 
        string json = stringbuilder.ToString();

        //Newtonsoft.Json.JsonConvert.Deserialize<UploadStatusList>(json) returns null for me here,so using Javascript serializer. No idea why !? 
        UploadStatusList list = new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<UploadStatusList>(json);
        foreach (var item in list.results)
        {
            Debug.Print("id: {0}, name: {1}", item.status, item.device_id);
        }
    }

公共部分类主窗口：窗口

//依赖属性
公共静态只读DependencyProperty actionListProperty=
DependencyProperty.Register（“actionList”，类型为（ObservableCollection），
typeof（主窗口），new FrameworkPropertyMetadata（null））；
//.NET属性包装器
公共可观察收集操作列表

公共主窗口（）

UploadStatusList=new System.Web.Script.Serialization.JavaScriptSerializer（）.Deserialize（json）；
foreach（list.results中的var项）
{
打印（“id:{0}，名称：{1}”，item.status，item.device_id）；
}
}
}

您做得很好，但只需在ItemSource的绑定中添加ElemmentName或使用DataContext即可

   <Window x:Name="mainWindow".....>
       <... ItemsSource="{Binding actionList.results, ElementName=mainWindow}".....

在代码隐藏中，您忘记了操作列表。添加（列表）

。抱歉，我删除了您的评论。您使用列表（

actionList

）。您在

操作列表中有一些对象，或者只有一个（在
主窗口构造函数中创建）。如果一个对象只需要将类型actionList更改为
public UploadStatusList actionList…
并在code
actionList=list
中。您从未设置DP
actionList
。此外，如果不从任何地方绑定，则无需创建DP。请参阅以下链接以更好地了解绑定：
