Question

序列化此类时遇到问题。我确保所有类组件类都是公共的，并确保每个类变量中都有非空值。我有什么理由不能将其序列化吗？

例外：

未处理的类型＆＃39; System.InvalidOperationException＆＃39;发生在System.Xml.dll中附加信息：有一个错误反映了类型＆Some39Space.TmpClass。

以下是代码：

public class TmpClass : ICloneable
{
    public List<string> str_pattern { get; set; } 
    public int group { get; set; }
    public double tp { get; set; }
    public double sl { get; set; }
    public int index { get; set; }
    public int num { get; set; }
    public string direction { get; set; }
    public string open;
    public string close;

    public TmpClass ()
    {
        open= "NA";
        close= "NA";
        direction  = "NA";
    }
    public Dictionary<string, SomeClass> stats = new Dictionary<string, SomeClass>();

    // Serialize Data
    public void Save(string fileName, string location)
    {
        string file = string.Concat(location, fileName);
        using (var stream = new FileStream(file, FileMode.Create))
        {
            XmlSerializer XML = new XmlSerializer(typeof(TmpClass));
            XML.Serialize(stream, this);
        }
    }

    // Deserialize Data
    public static TmpClass Load(string fileName, string location)
    {
        string file = string.Concat(location, fileName);
        using (var stream = new FileStream(file, FileMode.Open))
        {
            XmlSerializer XML = new XmlSerializer(typeof(TmpClass));
            return (TmpClass)XML.Deserialize(stream);
        }
    }

    //
    public object Clone()
    {
        return this.MemberwiseClone();
    }
}

以下是例外：

无法使用XML Serializer序列化Dictionary
