Windows窗体-返回第一个窗体

我无法从Form2返回到Form1。

我正在尝试做的是：

单击按钮，然后单击form1，就可以将您带到form2

单击按钮时，form2将带您进入form1。

我尝试更改this->Visible = false;为this->Close();两种形式，但出现此错误

1>c:\users\form2.h(172): error C2065: 'form1' : undeclared identifier
1>c:\users\form2.h(172): error C2065: 'go_form1' : undeclared identifier
1>c:\users\form2.h(172): error C2061: syntax error : identifier 'menu_form'
1>c:\users\form2.h(173): error C2065: 'go_form1' : undeclared identifier
1>c:\users\form2.h(173): error C2227: left of '->Show' must point to class/struct/union/generic type

表格1

#include "form2.h"

private: System::Void start_button_Click(System::Object^  sender, System::EventArgs^  e) {
                 form2^ go_form2 = gcnew form2();
                 go_form2->Show();
                 this->Visible = false;
             }

表格2

#include "form1.h"

    private: System::Void start_button_Click(System::Object^  sender, System::EventArgs^  e) {
                     form1^ go_form1 = gcnew form1();
                     go_form1->Show();
                     this->Visible = false;
                 }

编辑：我试过这样做C ++ / CLI-如何打开一个新窗体并返回现在它打开第二个窗体，但在小窗口中没有任何内容

表格2

public ref class Form2 : public System::Windows::Forms::Form
    {
    public:
        Form2(void)
        {
            InitializeComponent();
        }
    public:
        Form2(System::Windows::Forms::Form ^ form1)
        {
            otherform = form1;
            InitializeComponent();
        }
private: System::Windows::Forms::Form ^ otherform;

private: System::Void Button_Click(System::Object^  sender, System::EventArgs^  e) {
            this->Hide();
            otherform->Show();
         }
