c++ - C++ windows窗体中的向量使用

Question

我正在使用 Visual Studio 2010 使用 Windows 窗体在 C++ 中进行编程来创建东西。他妈的讨厌它！

我想使用向量数组，我可以在本机 C++ 程序中轻松做到这一点，但我找不到任何可在表单中使用的遍历示例。

我在 main.cpp 中包含了 cliext/vector。如果我尝试将其包含在 Form.h 中，它会告诉我我做不到。当我尝试创建一个向量数组变量时，它告诉我我有一个

语法错误缺少';' 在'<'之前

我要做的就是创建 6 个数组（int/float/2 Point/2 String^），我也可以轻松添加数据，然后稍后再读回来。

我只需要一个如何设置它的示例。

[编辑]

不确定发布不起作用的代码将如何帮助获得指向工作示例的链接，但可以肯定......我会同意的。

哦，如果我添加 using namespace cliext; 在我的 .h 文件的顶部，我被告知 cliext 不是类或命名空间。

第一次加载的错误都是关于向量语法是如何错误的……然后我得到了一大堆错误，这些错误源于后来未定义的变量。

如果您不专注于使用名为 的函数push_back，但Add可以使用 ，则可以使用 .NET 提供的集合来存储 .NET 数据。

using namespace System::Collections::Generic;

List<int> vShape;
List<Point> vfirstPoint;
List<Point> vSize;
List<float> vPix;
List<String^> vfillColor;
List<String^> vlineColor;

System::Collections::Generic::List<T>类似于std::vector。 System::Collections::Generic::LinkedList<T>到std::list和System::Collections::Generic::Dictionary<TKey, TValue>到std::unordered_map。
