推荐答案
_splitpath 应该做你需要的.您当然可以手动完成,但 _splitpath
也可以处理所有特殊情况.
_splitpath should do what you need. You could of course do it manually but _splitpath
handles all special cases as well.
正如 BillHoag 提到的,建议使用更安全的 _splitpath
版本,称为 _splitpath_s 可用时.
As BillHoag mentioned it is recommended to use the more safe version of _splitpath
called _splitpath_s when available.
或者如果你想要一些便携的东西,你可以做这样的事情
Or if you want something portable you could just do something like this
std::vector<std::string> splitpath(
const std::string& str
, const std::set<char> delimiters)
{
std::vector<std::string> result;
char const* pch = str.c_str();
char const* start = pch;
for(; *pch; ++pch)
{
if (delimiters.find(*pch) != delimiters.end())
{
if (start != pch)
{
std::string str(start, pch);
result.push_back(str);
}
else
{
result.push_back("");
}
start = pch + 1;
}
}
result.push_back(start);
return result;
}
...
std::set<char> delims{'\'};
std::vector<std::string> path = splitpath("C:\MyDirectory\MyFile.bat", delims);
cout << path.back() << endl;
