我有MainWindow类，有按钮。 单击按钮时，它会打开新表单，此表单需要放入向量。
我的代码是这样的：
类动作控件在向量和类中添加表单标题是向量的结构。我将来需要类bcz我想在一瞬间关闭向量中的所有表单。
#pragma once
#include "MyForm.h"
#include <vector>
using namespace std;
ref class Header
{
public:
Client::MyForm ^x;
void Close(){ x->Close();}
};
class Action
{
public:
vector<Header> vec;
};
当我在类Action中添加向量时，此代码崩溃了。输出是：

我认为，std :: vector不支持VS（^）中的智能指针，请帮助我，我该如何修复它，我需要有打开表单的向量。
答案 0 :(得分：0)
^不是智能指针＆＃39;，它是.Net管理参考。它不能放入C ++容器中，只能放入.Net容器中。
