};
#endif//INIREADER_H
2.IniReader.cpp文件：

returniResult;
}
floatCIniReader::ReadFloat(LPCTSTRszSection,LPCTSTRszKey,floatfltDefaultValue)
{
TCHARszResult[255];
TCHARszDefault[255];
floatfltResult;
_stprintf_s(szDefault,255,TEXT("%f"),fltDefaultValue);
GetPrivateProfileString(szSection,szKey,szDefault,szResult,255,m_szFileName);

returnbolResult;
}

{
LPTSTRszResult=newTCHAR[255];
memset(szResult,0x00,sizeof(szResult));
GetPrivateProfileString(szSection,szKey,szDefaultValue,szResult,255,m_szFileName);
returnszResult;
}
3.IniWriter.h文件：
#ifndefINIWRITER_H
#defineINIWRITER_H
#include<windows.h>
classCIniWriter
{
public:
CIniWriter(LPCTSTRszFileName);
voidWriteInteger(LPCTSTRszSection,LPCTSTRszKey,intiValue);
voidWriteFloat(LPCTSTRszSection,LPCTSTRszKey,floatfltValue);
voidWriteBoolean(LPCTSTRszSection,LPCTSTRszKey,boolbolValue);
voidWriteString(LPCTSTRszSection,LPCTSTRszKey,LPCTSTRszValue);
private:
TCHARm_szFileName[255];
};
#endif//INIWRITER_H
4.IniWriter.cpp文件：
#include"IniWriter.h"
#include<iostream>
#include<windows.h>
CIniWriter::CIniWriter(LPCTSTRszFileName)
{
memset(m_szFileName,0x00,sizeof(m_szFileName));
memcpy(m_szFileName,szFileName,_tcslen(szFileName)*sizeof(TCHAR));
}
voidCIniWriter::WriteInteger(LPCTSTRszSection,LPCTSTRszKey,intiValue)
{
TCHARszValue[255];
_stprintf_s(szValue,255,TEXT("%d"),iValue);
WritePrivateProfileString(szSection,szKey,szValue,m_szFileName);
}
voidCIniWriter::WriteFloat(LPCTSTRszSection,LPCTSTRszKey,floatfltValue)
{
TCHARszValue[255];
_stprintf_s(szValue,255,TEXT("%f"),fltValue);
WritePrivateProfileString(szSection,szKey,szValue,m_szFileName);
}
voidCIniWriter::WriteBoolean(LPCTSTRszSection,LPCTSTRszKey,boolbolValue)
{
TCHARszValue[255];
_stprintf_s(szValue,255,TEXT("%s"),bolValue?TEXT("True"):TEXT("False"));
WritePrivateProfileString(szSection,szKey,szValue,m_szFileName);
}
voidCIniWriter::WriteString(LPCTSTRszSection,LPCTSTRszKey,LPCTSTRszValue)
{
WritePrivateProfileString(szSection,szKey,szValue,m_szFileName);
}
5.main.cpp文件：
#ifdefined(UNICODE)||defined(_UNICODE)
#definetcoutstd::wcout
#else
#definetcoutstd::cout
#endif
#include<iostream>
#include<windows.h>
#include"IniWriter.h"
#include"IniReader.h"
int_tmain(intargc,_TCHAR*argv[])
{
CIniWriteriniWriter(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);
CIniReaderiniReader(TEXT(".\\initest.ini"));
LPTSTRszName=iniReader.ReadString(TEXT("Setting"),TEXT("Name"),TEXT(""));
intiAge=iniReader.ReadInteger(TEXT("Setting"),TEXT("Age"),25);
