'Data.TimeLineChartedDay []'类型的对象无法转换为'Data.TimeLineChartedDay []'类型？

Question

我在VS2008中遇到以下设计器错误:

 Object of type 'Data.TimeLineChartedDay[]' cannot be 
 converted to type 'Data.TimeLineChartedDay[]'.  

???

public class TimeLineDisplay     
{
    private List<TimeLineChartedDay> chartedDays = new List<TimeLineChartedDay>();

    public List<TimeLineChartedDay> ChartedDays         
    {
        get { return chartedDays; }
        set { chartedDays = value;  }
    }
}

[Serializable]
public class TimeLineChartedDay
{
    private DateTime date;
    private int chartValue;

    public DateTime Date
    {
        get { return date; }
        set { date = value; }
    }

    public int ChartValue
    {
        get { return chartValue; }
        set { chartValue = value; }
    }

    public TimeLineChartedDay()
    { 

    }
}

在此错误之前发生了以下情况:我添加了一个自编写的控件.VS崩溃时出现以下消息:"Class TimeLineChartedDay未标记为可序列化".我发现这很奇怪,因为它写在另一台机器上,并没有抱怨'Serializable'属性.我将该属性添加到了类中,并偶然发现了前面提到的错误.

您的控件正在尝试序列化类实例,但可能不应该.

您应该添加[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]到公开的属性TimeLineDisplay.
