1、建立一个操作Ini文件的类，将操作ini文件的相关方法都封装到该类中

MyIniClass.h文件

#pragma once#include <vector>using std::vector;class CMyIniClass{public:CMyIniClass();virtual ~CMyIniClass();//    设置ini文件路径//    成功返回TRUE;否则返回FALSEBOOL         SetPath(CString strPath);//    检查section是否存在//    存在返回TRUE;否则返回FALSEBOOL         SectionExist(CString strSection);//    从指定的Section和Key读取KeyValue//    返回KeyValueCString         GetKeyValue(CString    strSection,CString    strKey);//    设置Section、Key以及KeyValue，若Section或者Key不存在则创建void          SetKeyValue(CString    strSection,CString    strKey,CString    strKeyValue);//    删除指定Section下的一个Keyvoid          DeleteKey(CString strSection,CString strKey);//    删除指定的Section以及其下的所有Keyvoid          DeleteSection(CString strSection);//    获得所有的Section//    返回Section数目int              GetAllSections(CStringArray& strArrSection);//    根据指定Section得到其下的所有Key和KeyValue//    返回Key的数目int              GetAllKeysAndValues(CString strSection,CStringArray& strArrKey,CStringArray& strArrKeyValue);//       删除所有Sectionvoid          DeleteAllSections();//初始化信息void initIniFile(LPCTSTR path);//获取指定ini中节中所有的valuevoid getValue(CString strPath, CString strSections);//返回vectorvector<CString>  getValueVctr();void getSysCurName(CString & strName);private://       ini文件路径CString m_strPath;vector<CString> m_valueVctr;};

MyIniClass.cpp文件

#include "stdafx.h"#include "MyIniClass.h"#define         MAX_SECTION                260        //Section最大长度#define         MAX_KEY                         260        //KeyValues最大长度#define         MAX_ALLSECTIONS     65535    //所有Section的最大长度#define         MAX_ALLKEYS              65535    //所有KeyValue的最大长度CMyIniClass::CMyIniClass() : m_valueVctr(NULL){}CMyIniClass::~CMyIniClass(){}////////////////////////////////////////////////////////////////////////////   Public Functions//////////////////////////////////////////////////////////////////////////BOOL CMyIniClass::SetPath(CString strPath){m_strPath = strPath;//       检查文件是否存在DWORD  dwFlag = GetFileAttributes((LPCTSTR)m_strPath);//       文件或者路径不存在，返回FALSEif (0xFFFFFFFF == dwFlag)return FALSE;//       路径是目录，返回FALSEif (FILE_ATTRIBUTE_DIRECTORY & dwFlag)return FALSE;return TRUE;}BOOL CMyIniClass::SectionExist(CString strSection){TCHAR chSection[MAX_SECTION];DWORD dwRetValue;dwRetValue = GetPrivateProfileString((LPCTSTR)strSection,NULL,_T(""),chSection,sizeof(chSection) / sizeof(TCHAR),(LPCTSTR)m_strPath);return (dwRetValue > 0);}CString CMyIniClass::GetKeyValue(CString strSection,CString strKey){TCHAR         chKey[MAX_KEY];DWORD         dwRetValue;CString strKeyValue = _T("");dwRetValue = GetPrivateProfileString((LPCTSTR)strSection,(LPCTSTR)strKey,_T(""),chKey,sizeof(chKey) / sizeof(TCHAR),(LPCTSTR)m_strPath);strKeyValue = chKey;return strKeyValue;}void CMyIniClass::SetKeyValue(CString strSection,CString strKey,CString strKeyValue){WritePrivateProfileString((LPCTSTR)strSection,(LPCTSTR)strKey,(LPCTSTR)strKeyValue,(LPCTSTR)m_strPath);}void CMyIniClass::DeleteKey(CString strSection, CString strKey){WritePrivateProfileString((LPCTSTR)strSection,(LPCTSTR)strKey,NULL,          //       这里写NULL,则删除Key(LPCTSTR)m_strPath);}void CMyIniClass::DeleteSection(CString strSection){WritePrivateProfileString((LPCTSTR)strSection,NULL,NULL,          //       这里都写NULL,则删除Section(LPCTSTR)m_strPath);}int CMyIniClass::GetAllSections(CStringArray& strArrSection){int dwRetValue, i, j, iPos = 0;TCHAR chAllSections[MAX_ALLSECTIONS];TCHAR chTempSection[MAX_SECTION];ZeroMemory(chAllSections, MAX_ALLSECTIONS);ZeroMemory(chTempSection, MAX_SECTION);dwRetValue = GetPrivateProfileSectionNames(chAllSections,MAX_ALLSECTIONS,m_strPath);//       因为Section在数组中的存放形式为“Section1”，0，“Section2”，0，0。//       所以如果检测到连续两个0，则breakfor (i = 0;

2、在mfc中的按钮事件中进行调用

//判断ini配置文件是否存在   不存在则创建CString path = _T(".\\myIni.ini");if (!m_IniFile.SectionExist(path)){m_IniFile.initIniFile(path);}

也可以使用如下进行测试

  void CMFCApplication1Dlg::OnBnClickedButton1(){      CIniFile file;         CStringArray arrSection, arrKey, arrkeyValue;         file.SetPath("f:\\ myfile.ini");         CString str="";          if(file.SectionExist("student"))         {                  //str="15"                   str = file.GetKeyValue("student", "female");                                     //设置number为50                  file.SetKeyValue("student", "number", "50");                    //因为在student中computer_num不存在，所以增加一项                  file.SetKeyValue("student", "computer_num", "30");                    //得到所有section                   int num = file.GetAllSections(arrSection);                   str = "";                   for(int i=0; i<num; i++)                   {                            str += arrSection[i] + " ";//str="student computer ";                   }                    //得到所有Key和KeyValue                   int num = file.GetAllKeysAndValues("computer", arrKey, arrkeyValue);                   str = "";                   for(int j=0; j<num; j++)                   {                            //arrKey保存了computer下所有的Key                            //arrkeyValue保存了computer下所有的KeyValue                            str = arrKey[j];                            str = arrkeyValue[j];                   }                   //删除student下的computer_num                  file.DeleteKey("student", "computer_num");                    //删除student                  file.DeleteSection("student");     } }
