【问题描述】：
我很难找出为什么会出现此错误。我正在 Visual Studio 上使用 C++ 开发 CLR UI 窗体应用程序。
如果我尝试这样做
private: int valueInSquare[9];
我收到一条错误消息，提示“托管类的成员不能是标准数组”
如果我把它改成
private: array<int>^valueInSquare;
我在尝试查看我的表单的头文件设计时收到错误提示，
C++ CodeDOM 解析器错误：行：94，列：24 --- 未知类型 'array^'。请确保引用了包含此类型的程序集。如果此类型是您的开发项目的一部分，请确保该项目已成功构建。
这里是代码的一部分，因为很多是通过在我的头文件中使用设计器预先生成的。

【问题讨论】：
-
C++ 中没有“托管类”之类的东西，
private: array<int>^valueInSquare;在语法上也是无效的。请将语言标签从 [c++] 更改为您实际使用的方言，例如 C++/CLI。 -
array<int>和valueInSquare;之间有一个插入符号 -
@BaummitAugen 我的错，我的教授通常说 Visual C++ 这是我第一次使用该语言，所以我认为这就是我正在使用的语言
-
@SidS 删除插入符号说“这里不允许使用 C++/CLI 数组类型”有没有办法在 Visual c++ 中定义数组？
-
Visual C++ 也不是一种语言，它是一种 IDE 或编译器。你真的应该弄清楚你使用的是什么语言，否则，提出一个有用的问题可能会很困难。
