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，每当我尝试使用表单1打开表单2时，我得到的就是这些错误......

为什么我不能打开表格2？
2010 \ projects \ reportaliation \ reportaliation \ Form1.h（431）：错误C2065：'Form2'：未声明的标识符
是指...

答案 0 :(得分：0)
您收到错误，因为您的头文件中存在循环依赖关系。 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。
答案 1 :(得分：0)
请按照以下步骤操作：
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：
Form2^ testDialog = gcnew Form2;
testDialog->ShowDialog (this);
delete testDialog;
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：
#include "stdafx.h"
#include "Form1.h"
按如下方式编辑：
#include "stdafx.h"
#include "Form2.h"
#include "Form1.h"
注意：不应更改#include的顺序。
来吧，运行你的项目并享受!!!!
