我正在使用Visual Studio 2010，我想在C ++中切换两个表单。我一直在做一些谷歌搜索，如果没有全部关于c＃和visual basic的话，我无法找到任何解决方案。
到目前为止，我一直收到此错误：
错误12错误C2227：左边的＆＃39; - ＆gt; ShowDialog＆＃39;必须指向class / struct / union / generic类型 错误4错误C2065：＆＃39; Form2＆＃39; ：未声明的标识符
错误11错误C2065：＆＃39; f1＆＃39; ：未声明的标识符
错误5错误C2061：语法错误：标识符＆＃39; Form2＆＃39;
错误10错误C2061：语法错误：标识符＆＃39; Form1＆＃39;
我在代码中唯一提到的是
表格1：
#include "Form2.h"
和按钮事件
Form2^form2 = gcnew Form2();
form2->ShowDialog();
this->Hide();
并以表格2
#include "Form1.h"
和按钮事件
Form1^f1 = gcnew Form1();
this->Hide();
f1->ShowDialog();
这是否正确？这是我的第一篇文章，所以告诉我还需要添加什么 帮助使它更清晰 编辑： 窗体2

在您的实施文件中，您需要编写
using namespace MBED4;
或
using MBED4::Form2;
前
Form2^form2 = gcnew Form2();
或写
MBED4::Form2^form2 = gcnew MBED4::Form2();
form2->ShowDialog();
this->Hide();
