c++ 里面的字符类型转换

char* 转换成 LPCTSTR

char ch[1024] = "xxxx";
int num = MultiByteToWideChar(0,0,ch,-1,NULL,0);
wchar_t *wide = new wchar_t[num];
MultiByteToWideChar(0,0,ch,-1,wide,num);

LPCTSTR 转换成 char *

wchar_t widestr[1024] = L"xxxx";
int num = WideCharToMultiByte(CP_OEMCP,NULL,widestr,-1,NULL,0,NULL,FALSE); char *pchar = new char[num]; WideCharToMultiByte (CP_OEMCP,NULL,widestr,-1,pchar,num,NULL,FALSE);
