我正在尝试制作Windows窗体，这是Form1.h：

#pragma once

#include"student.h"

        //
    }

    ~Form1()
    {
        if (components)
        {
            delete components;
        }
    }

    }
#pragma endregion
    student s;
private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) {


             int id= System::Convert::ToInt32(textBox1->Text);
               int g1= System::Convert::ToInt32(textBox2->Text);
               int g2= System::Convert::ToInt32(textBox3->Text);
               int g3= System::Convert::ToInt32(textBox4->Text);
         s.setStudent(id,g1,g2,g3);

         textBox5->Text=  System::Convert::ToString(s.maxGrade());




         }
private: System::Void Form1_Load(System::Object^  sender, System::EventArgs^  e) {
         }
};
}

在Header Files上我添加了头文件student.h并在其中编写了class student： student.h：

#include<iostream>
#include<string>
using namespace std;

class student
{
int id;
int grade1,grade2,grade3;

public:

student()
{




}


void setStudent(int a,int b,int c,int d)
{
     id=a;
    grade1=b;
    grade2=c;
    grade3=d;


}


int maxGrade()
{
  int max=grade1;
  if(grade2>max)
    max=grade2;

  if(grade3>max)
  {
     max=grade3;

  }


  return max;




}



 };

但编译器给了我错误：

  

错误3错误C2662：'student :: maxGrade'：无法将'this'指针从'student'转换为'student＆amp;'

     

错误2错误C2662：'student :: setStudent'：无法将'this'指针从'student'转换为'student＆amp;'

     

错误1错误C4368：无法将's'定义为托管'formApp :: Form1'的成员：不支持混合类型

请告诉我将学生类添加到Windows表单应用程序并使用它的正确方法。

1 个答案:

答案 0 :(得分：0)

正如您现在定义的那样，student是一个非托管类，Form1是托管类。托管类不允许将非托管类作为内联字段。您可以通过以下两种方式之一解决此问题：

  1. 改为使s成为指针类型（student*），并在Form1的构造函数中创建一个新对象。
  2. （首选）将student更改为托管类（ref class student），并将s设为托管句柄（student^）。

    3. 现在，如果您尝试在C ++ / CLI中编写此内容，那么您将面临许多麻烦。考虑切换到C＃，它将使WinForms开发变得更容易。
