windows - 如何制作 System::Windows::Forms::Checkbox^ 的向量/数组

Question

找不到此问题的任何答案，甚至没有提出任何问题。所以我想做的是一个 std::vector，也许只是一个普通的复选框数组。

std::vector< System::Windows::Forms::CheckBox^ >m_items;
m_items.push_back( myCheckbox );

这就是我目前拥有的，但显然不起作用。那么有没有人对如何让它工作有任何想法，因为我已经尽我所能，但矢量似乎不支持复选框。

如果您需要错误代码:

Answer 1

常规std::vector不支持 CLR 引用类型。相反，您必须使用 cliext::vector .包括以下内容:

#include <cliext/vector>

并用于:

cliext::vector<System::Windows::Forms::CheckBox^> items;
items.push_back(myCheckBox);

当然，您也可以使用常规的 .Net 集合，例如 List<T> ，其行为类似于 vector .
