我正在使用microsoft Visual c制作视频游戏，我用CLR语言编写所有这些，但我这个奇怪的问题....
出于某种原因，每当我尝试用表格1打开表格2时，我得到的都是这些错误......

您收到错误，因为您的头文件中存在循环依赖项 . 您的编译器正在尝试编译Form2.cpp，其中包含Form1.h，在Form1.h中包含Form2.h，在Form2.h中包含Form1.h . 您需要使用前向声明，或更改您的设计，以便您的课程更少耦合 .
此外，本身不包含头文件..
更一般地说，您不应该在头文件中实现函数定义，而是使用.cpp文件 . 我也认为您不需要使用预编译的头文件（stdAfx.h），您应该在创建Visual Studio项目时禁用该复选框 .
跟着这些步骤：
创建一个新项目 . Form1默认创建 .
在Form1上创建一个按钮，双击它并粘贴下面的代码：
转到解决方案资源管理器，右键单击该项目并添加一个新表单并将其另存为Form2 .
双击Form1.cpp，您将看到它以以下行开头：
编辑如下：
注意：不应更改#include的顺序 .
来吧，运行你的项目，享受!!!!
