c++类和C#中定义类的方法异同之处：
1. 相同处：
1.1.都需要使用 class标识；
1.2.都包含有成员：函数，属性；
1.3.都有private public protect 标识的成员
2.不同之处：
2.2. C++申明类及成员时格式：
class Member
{
public:
void SetName(string name);
string GetName();
private:
string name;
};
一般在class的末尾处需要一个英文分割符号“;”，public private protect
成员时，集中式生命，而这是在c#中没有出现，或者没有这么严格要求。
public class Member
{
private string name;public void SetName(string name)
{
this.name=name;
}public string GetName()
{
return this.name;
}
}或者 简单的一个get;set;就可以替代上边的函数，不过getName,setName函数是在预编译时，自动生成的。
public class Member
{
public string Name{get;set;}
}
2.2. 以来文件的引入方式不同：
c++ 使用:
#include<iostream>
using std::cout#include “test.h”
c#：
using System;
using System.IO;
怎么写一个完成c++的类：
#include <iostream>
using std::cout;
using std::endl;#include <string> // program uses C++ standard string class.
using std::string;#include <conio.h>
// GradeBook class definition
class GradeBook
{
public:
// constructor initializes courseName with string supplited as argument.
GradeBook(string name)
{
this->courseName=name;
} // end GradeBook constructor// function to set the course name
void setCourseName(string name)
{
this->courseName=name;// store the course name in the object.
}// end function setCourseName// function to get the course name.
string getCourseName()
{
return courseName;// return object‘s courseName
}// end function getCourseName// display a welcome message to the GradeBook user
void displayMessage()
{
// call getCourseName to get the courseName
cout<<"Welcome to the grade book for \n"<<getCourseName()<<"|"<<endl;
}// end function displayMessage
private :
string courseName;
};// end class GradeBook// function main begins program execution
int main()
{
// create two GradeBook objects.
GradeBook gradeBook1("CS101 Introduction to C++ programing");;
GradeBook gradeBook2("CS102 Data Structures in C++");// display initial value of courseName for each GradeBook
cout<<"gradeBook1 created for course:"<<endl;
gradeBook1.displayMessage();
cout<<"gradeBook2 created for course:"<<endl;
gradeBook2.displayMessage();cout<<"Test the get function"<<endl;
cout<<"gradeBook1 call getCourseName"<<gradeBook1.getCourseName()<<endl;
cout<<"gradeBook2 call getCourseName"<<gradeBook2.getCourseName()<<endl;
std::cin.get();return 0; // indicates successful termination.
}// end main
