C#嵌套类的访问方法

对于以下数据，如何在运行时通过字符串来得到静态变量uipath的值。

public class gamemainmenu : uiclass
{
    public class jetpack : uiclass
    {
        public static uipath uipath = new uipath("uiprefabs/gamemainmenu/jetpack/jetpack.prefab");
    }
}

像下面这样即可。

bindingflags flag = bindingflags.static | bindingflags.public;
type type = type.gettype("gamemainmenu+jetpack");
system.reflection.fieldinfo key = type.getfield("uipath", flag);
debug.log((key.getvalue(null) as uipath).tostring());
