c++ - C++：将 wstring 转换为无符号字符

Question

我试图将 wstring 转换为 unsigned char。我试过_wtoc，但这不存在。

_wto 风格有转换吗？

谢谢你。

Answer 1

好吧，我现在这样做：

wstring sThis=L"12";

unsigned int i;
i=_wtoi(sThis.c_str());

unsigned char c=(unsigned char)i;

Answer 2

我这样做

wstring wsWideString
UINT uSize = wsWideString.length();
unsigned char * ptrUChar = new unsigned char[uSize+1];
memset(ptrUChar ,'\0',uSize+1);
for(UINT i=0;i<uSize;i++)
{
ptrUChar [i] = wsWideString[i];
}

//when finished
delete [] ptrUChar ;
ptrUChar  = NULL;
