Question

我有一个父对象，想要动态遍历子对象。

public class Class1
{
    public Class1()
    {
        this.MyProperty1 = new List<Class2>();
    }

    public int MyProperty { get; set; }
    public List<Class2> MyProperty1 { get; set; }
}
class Class2
{
    public Class2()
    {
        this.MyProperty2 = new List<Class3>();
    }

    public int MyProperty { get; set; }
    public List<Class3> MyProperty2 { get; set; }
}
class Class3
{
    public int MyProperty { get; set; }

}

如果我需要在class3中阅读myproperty，我需要做类似

的事情

Class1.MyProperty1.Last().MyProperty2.Last().MyProperty

我想用动态动态做

请帮助

 public List<string> ChildPath(string ChildObject, List<string> ParentNameList, string AssembleyPath, string NameSpace, List<string> TraversedNodes)
    {
        Type ChildType = Type.GetType(NameSpace + ChildObject + AssembleyPath);
        List<string> Properties = ChildType.GetProperties().Where(x => x.PropertyType.IsClass && x.PropertyType.Assembly.GetName().Name != "mscorlib").Select(x => x.Name).ToList();

        ParentNameList.Add(ConfigurationManager.AppSettings[ChildObject].ToString());           
       // List<string> Properties = ConfigurationManager.AppSettings["Child_" + ChildObject].ToString().Split(',').ToList();
        int MaxIndex = 0;
        ChildObject = null;
        foreach (string item in Properties)
        {
            int PresIndex = TraversedNodes.IndexOf(item);
            if (MaxIndex <= PresIndex)
            {
                MaxIndex = PresIndex;
                ChildObject = item;
            }
        }
        if (ChildObject != null)
            PathTravarse(ChildObject, ParentNameList, AssembleyPath, NameSpace, TraversedNodes);
        return ParentNameList;
    }  


public object GetLastChild(object DataObject, List<string> Path)
    {

        object Destination = DataObject;
        int Count = Path.Count;
        for (int i = 0; i < Count; i++)
        {
            PropertyInfo ChildProperty = Destination.GetType().GetProperty(Path[i]);
            Destination = ChildProperty.GetValue(Destination, null);
            Destination = ((IList)Destination)[((IList)Destination).Count - 1];               
        }

        return Destination;

    }

         public object CreateChildInstance(object DataObject, List<string> Path, string ChildName,string AssembleyPath,string NameSpace)
    {

        object Destination = DataObject;
        int Count = Path.Count - 1;
        for (int i = 0; i < Count; i++)
        {
            PropertyInfo ChildProperty = Destination.GetType().GetProperty(Path[i]);
            Destination = ((IList)ChildProperty.GetValue(Destination, null));
            Destination = ((IList)Destination)[((IList)Destination).Count - 1];
        }
        PropertyInfo FinalChild = Destination.GetType().GetProperty(Path[Count]);
        Destination = FinalChild.GetValue(Destination, null);
        Type InstanceType = Type.GetType(NameSpace + ChildName + AssembleyPath);
        Destination.GetType().GetMethod("Add").Invoke(Destination, new[] { Activator.CreateInstance(InstanceType) });
        return DataObject;

    }
