我正在尝试创建一个调试器可视化器,显示任何控件的控制层次结构.已经完成,但是我收到了异常“Type not not as serializable”.
我该如何克服呢？ Control是一个.NET Windows Forms框架类型,我不能将其标记为可序列化.
解决方法
您还需要实现一个
VisualizerObjectSource来执行自定义序列化.
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注册可视化程序,对于此示例,可以这样做：
[assembly: DebuggerVisualizer(
typeof(ControlVisualizer),typeof(ControlVisualizerObjectSource),Target = typeof(System.Windows.Forms.Control),Description = "Control Visualizer")]
