您好:)在winForm中克隆包含其他对象和列表的对象时遇到问题。 我想克隆结构类型为的对象,下面提供了类 首先,我尝试了浅克隆

public Structure Clone()
{
    return this.MemberwiseClone() as Structure;
}
我发现它不起作用,所以我搜索并做了一个深度克隆

还有这个


但是内部
周期[,]
被克隆为
null
你能帮我@WiiMaxx吗

编辑2.0 我还检查了这篇关于3种方法中的深度克隆的文章,我认为我的代码中有循环引用,这就是为什么这对我不起作用的原因
结束编辑

好了,现在它应该真的可以工作了
(我还删除了我的旧解决方案,因为它完全不符合您的需要)
