c++ - TCHAR [ ] 转换为字符串

Question

我想转换TCHAR nameBuf[]成string.

TCHAR nameBuf[MAX_COMPUTERNAME_LENGTH + 2];

DWORD nameBufSize;

nameBufSize = sizeof nameBuf - 1;

GetComputerName(nameBuf, &nameBufSize); //store computer name into nameBuf

_tprintf(_T("%s"), nameBuf); //print the computer name

Answer 1

让我们明确类型。请参阅下面的修改代码：

WCHAR nameBuf[MAX_COMPUTERNAME_LENGTH + 2];

DWORD nameBufSize;

nameBufSize = sizeof nameBuf - 1;

GetComputerNameW(nameBuf, &nameBufSize); //store computer name into nameBuf

wprintf_s(L"%s", nameBuf); //print the computer name

Answer 2

如果你想使用窄字符（看起来像你这样做）那么这段代码

char nameBuf[MAX_COMPUTERNAME_LENGTH + 2];
DWORD nameBufSize;
nameBufSize = sizeof nameBuf - 1;
GetComputerNameA(nameBuf, &nameBufSize); //store computer name into nameBuf
printf_s("%s", nameBuf); //print the computer name
string NAME = nameBuf;
