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("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("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。
