调试器可视化工具和“类型未标记为可序列化”

发布于 2024-09-03 12:33:03 字数 142 浏览 4 评论 0原文

我正在尝试创建一个调试器可视化工具，它将显示任何Control的控制层次结构。它已完成，但我收到异常“类型未标记为可序列化”。

我该如何克服这个问题？控件是.NET Windows Forms框架类型，我无法将其标记为可序列化。

您还需要实现 VisualizerObjectSource 执行自定义序列化。

示例：

public class ControlVisualizerObjectSource : VisualizerObjectSource
{
    public override void GetData(object target, Stream outgoingData)
    {
        var writer = new StreamWriter(outgoingData);
        writer.WriteLine(((Control)target).Text);
        writer.Flush();
    }
}
public class ControlVisualizer : DialogDebuggerVisualizer
{
    protected override void Show(
        IDialogVisualizerService windowService,
        IVisualizerObjectProvider objectProvider)
    {
        string text = new StreamReader(objectProvider.GetData()).ReadLine();
    }
    public static void TestShowVisualizer(object objectToVisualize)
    {
        var visualizerHost = new VisualizerDevelopmentHost(
            objectToVisualize,
            typeof(ControlVisualizer),
            typeof(ControlVisualizerObjectSource));
        visualizerHost.ShowVisualizer();
    }
}
class Program
{
    static void Main(string[] args)
    {
        ControlVisualizer.TestShowVisualizer(new Control("Hello World!"));
    }
}

您还需要使用适当的 VisualizarObjectSource 注册可视化工具，在本示例中可能如下所示：

[assembly: DebuggerVisualizer(
    typeof(ControlVisualizer),
    typeof(ControlVisualizerObjectSource),
    Target = typeof(System.Windows.Forms.Control),
    Description = "Control Visualizer")]

You'll need to also implement a VisualizerObjectSource to perform custom serialization.

Example:

public class ControlVisualizerObjectSource : VisualizerObjectSource
{
    public override void GetData(object target, Stream outgoingData)
    {
        var writer = new StreamWriter(outgoingData);
        writer.WriteLine(((Control)target).Text);
        writer.Flush();
    }
}
public class ControlVisualizer : DialogDebuggerVisualizer
{
    protected override void Show(
        IDialogVisualizerService windowService,
        IVisualizerObjectProvider objectProvider)
    {
        string text = new StreamReader(objectProvider.GetData()).ReadLine();
    }
    public static void TestShowVisualizer(object objectToVisualize)
    {
        var visualizerHost = new VisualizerDevelopmentHost(
            objectToVisualize,
            typeof(ControlVisualizer),
            typeof(ControlVisualizerObjectSource));
        visualizerHost.ShowVisualizer();
    }
}
class Program
{
    static void Main(string[] args)
    {
        ControlVisualizer.TestShowVisualizer(new Control("Hello World!"));
    }
}

You'll also need to register the visualizer with the appropriated VisualizarObjectSource, which for this example could be something like this:

[assembly: DebuggerVisualizer(
    typeof(ControlVisualizer),
    typeof(ControlVisualizerObjectSource),
    Target = typeof(System.Windows.Forms.Control),
    Description = "Control Visualizer")]
