将 Dictionary<string, object> 转换为类和子类

Question

如何以递归方式将字典转换为类和子类？这些是我的课程：

public class UiItem
{
    public string id { get; set; }
    public string text { get; set; }
    public Rect rect { get; set; } 
}

public class Rect
{
    public int height { get; set; }
    public int width { get; set; }
    public int y { get; set; }
    public int x { get; set; }
}

我写了这个，但我不知道如何Rect在类中创建对象UiItem：

public static T GetObject<T>(this Dictionary<string, object> dict)
    {
        Type type = typeof(T);
        var obj = Activator.CreateInstance(type);

        foreach (var kv in dict)
        {
            var prop = type.GetProperty(kv.Key);
            object value = kv.Value;
            if (kv.Value.GetType() == typeof(Dictionary<string, object>))
            {
                value = GetObject<_???_>((Dictionary<string, object>) value) // <= This line
            }

            if(prop == null) continue;
            prop.SetValue(obj, value, null);
        }
        return (T)obj;
    }

最简单的方法是将类型作为参数传递，而不是使用泛型方法。那么这就是：

public static Object GetObject(this Dictionary<string, object> dict, Type type)
    {
        var obj = Activator.CreateInstance(type);

        foreach (var kv in dict)
        {
            var prop = type.GetProperty(kv.Key);
            if(prop == null) continue;

            object value = kv.Value;
            if (value is Dictionary<string, object>)
            {
                value = GetObject((Dictionary<string, object>) value, prop.PropertyType); // <= This line
            }

            prop.SetValue(obj, value, null);
        }
        return obj;
    }

然后，您可以创建一个执行转换的通用版本：

public static T GetObject<T>(this Dictionary<string, object> dict)
{
    return (T)GetObject(dict, typeof(T));
}
