本文实例讲述了C++读写INI配置文件的类。分享给大家供大家参考。具体如下：

1. IniReader.h文件：

#ifndef INIREADER_H#define INIREADER_H#include <windows.h>class CIniReader{public: CIniReader(LPCTSTR szFileName); int ReadInteger(LPCTSTR szSection, LPCTSTR szKey, int iDefaultValue); float ReadFloat(LPCTSTR szSection, LPCTSTR szKey, float fltDefaultValue); bool ReadBoolean(LPCTSTR szSection, LPCTSTR szKey, bool bolDefaultValue); LPTSTR ReadString(LPCTSTR szSection, LPCTSTR szKey, LPCTSTR szDefaultValue);private: TCHAR m_szFileName[255];};#endif //INIREADER_H

2. IniReader.cpp文件：

#include "IniReader.h"#include <iostream>#include <windows.h>CIniReader::CIniReader(LPCTSTR szFileName){ memset(m_szFileName, 0x00, sizeof(m_szFileName)); memcpy(m_szFileName, szFileName, _tcslen(szFileName)*sizeof(TCHAR));}int CIniReader::ReadInteger(LPCTSTR szSection, LPCTSTR szKey, int iDefaultValue){ int iResult = GetPrivateProfileInt(szSection, szKey, iDefaultValue, m_szFileName); return iResult;}float CIniReader::ReadFloat(LPCTSTR szSection, LPCTSTR szKey, float fltDefaultValue){ TCHAR szResult[255]; TCHAR szDefault[255]; float fltResult; _stprintf_s(szDefault, 255, TEXT("%f"),fltDefaultValue); GetPrivateProfileString(szSection, szKey, szDefault, szResult, 255, m_szFileName); fltResult = (float)_tstof(szResult); return fltResult;}bool CIniReader::ReadBoolean(LPCTSTR szSection, LPCTSTR szKey, bool bolDefaultValue){ TCHAR szResult[255]; TCHAR szDefault[255]; bool bolResult; _stprintf_s(szDefault, 255, TEXT("%s"), bolDefaultValue? TEXT("True") : TEXT("False")); GetPrivateProfileString(szSection, szKey, szDefault, szResult, 255, m_szFileName); bolResult = (_tcscmp(szResult, TEXT("True")) == 0 || _tcscmp(szResult, TEXT("true")) == 0) ? true : false; return bolResult;}LPTSTR CIniReader::ReadString(LPCTSTR szSection, LPCTSTR szKey, LPCTSTR szDefaultValue){ LPTSTR szResult = new TCHAR[255]; memset(szResult, 0x00, sizeof(szResult)); GetPrivateProfileString(szSection, szKey, szDefaultValue, szResult, 255, m_szFileName); return szResult;}

3. IniWriter.h文件：

#ifndef INIWRITER_H#define INIWRITER_H#include <windows.h>class CIniWriter{public: CIniWriter(LPCTSTR szFileName); void WriteInteger(LPCTSTR szSection, LPCTSTR szKey, int iValue); void WriteFloat(LPCTSTR szSection, LPCTSTR szKey, float fltValue); void WriteBoolean(LPCTSTR szSection, LPCTSTR szKey, bool bolValue); void WriteString(LPCTSTR szSection, LPCTSTR szKey, LPCTSTR szValue);private: TCHAR m_szFileName[255];};#endif //INIWRITER_H

4. IniWriter.cpp文件：

#include "IniWriter.h"#include <iostream>#include <windows.h> CIniWriter::CIniWriter(LPCTSTR szFileName){ memset(m_szFileName, 0x00, sizeof(m_szFileName)); memcpy(m_szFileName, szFileName, _tcslen(szFileName)*sizeof(TCHAR));}void CIniWriter::WriteInteger(LPCTSTR szSection, LPCTSTR szKey, int iValue){ TCHAR szValue[255]; _stprintf_s(szValue, 255, TEXT("%d"), iValue); WritePrivateProfileString(szSection, szKey, szValue, m_szFileName); }void CIniWriter::WriteFloat(LPCTSTR szSection, LPCTSTR szKey, float fltValue){ TCHAR szValue[255]; _stprintf_s(szValue, 255, TEXT("%f"), fltValue); WritePrivateProfileString(szSection, szKey, szValue, m_szFileName); }void CIniWriter::WriteBoolean(LPCTSTR szSection, LPCTSTR szKey, bool bolValue){ TCHAR szValue[255]; _stprintf_s(szValue, 255, TEXT("%s"), bolValue ? TEXT("True") : TEXT("False")); WritePrivateProfileString(szSection, szKey, szValue, m_szFileName); }void CIniWriter::WriteString(LPCTSTR szSection, LPCTSTR szKey, LPCTSTR szValue){ WritePrivateProfileString(szSection, szKey, szValue, m_szFileName);}

5. main.cpp文件：

#if defined(UNICODE) || defined(_UNICODE)#define tcout std::wcout#else#define tcout std::cout#endif#include <iostream>#include <windows.h>#include "IniWriter.h"#include "IniReader.h"int _tmain(int argc, _TCHAR* argv[]){ CIniWriter iniWriter(TEXT(".\\initest.ini")); iniWriter.WriteString(TEXT("Setting"), TEXT("Name"), TEXT("jianxx")); iniWriter.WriteInteger(TEXT("Setting"), TEXT("Age"), 27); iniWriter.WriteFloat(TEXT("Setting"), TEXT("Height"), 1.82f); iniWriter.WriteBoolean(TEXT("Setting"), TEXT("Marriage"), false); CIniReader iniReader(TEXT(".\\initest.ini")); LPTSTR szName = iniReader.ReadString(TEXT("Setting"), TEXT("Name"), TEXT("")); int iAge = iniReader.ReadInteger(TEXT("Setting"), TEXT("Age"), 25); float fltHieght = iniReader.ReadFloat(TEXT("Setting"), TEXT("Height"), 1.80f); bool bMarriage = iniReader.ReadBoolean(TEXT("Setting"), TEXT("Marriage"), true); tcout<<"Name:"<<szName<<std::endl <<"Age:"<<iAge<<std::endl <<"Height:"<<fltHieght<<std::endl <<"Marriage:"<<bMarriage<<std::endl; delete szName; return 1; }

希望本文所述对大家的C++程序设计有所帮助。
