C/C++，Windows/MFC__char与TCHAR相互转化

char与TCHAR之间的转化主要用到函数MultiByteToWideChar和WideCharToMultiByte

char转TCHAR

如果不是Unicode字符集，就不需要转换，直接复制即可，如果不确定是否使用Unicode字符集，可以这样写

[cpp] view
plaincopy

char strUsr[10] = "Hello";

TCHAR Name[100];

#ifdef UNICODE

MultiByteToWideChar(CP_ACP, 0, strUsr, -1, Name, 100);

#else

strcpy(Name, strUsr);

#endif

TCHAR转char



[cpp] view
plaincopy

char* ConvertLPWSTRToLPSTR (LPWSTR lpwszStrIn)

{

LPSTR pszOut = NULL;

if (lpwszStrIn != NULL)

{

int nInputStrLen = wcslen (lpwszStrIn);



// Double NULL Termination

int nOutputStrLen = WideCharToMultiByte (CP_ACP, 0, lpwszStrIn, nInputStrLen, NULL, 0, 0, 0) + 2;

pszOut = new char [nOutputStrLen];



if (pszOut)

{

memset (pszOut, 0x00, nOutputStrLen);

WideCharToMultiByte(CP_ACP, 0, lpwszStrIn, nInputStrLen, pszOut, nOutputStrLen, 0, 0);

}

}

return pszOut;

}
