C++中，integer與string間的轉換是躲不掉的，所以如何轉換也就出來了各種的版本。像我是用std::ostringstream的?？紤]到其性能，今天到網上找找，發現都差不多，只是有些寫的好看的很。

I would change the above template as follows:
template <class T>
void StringOf(const T& object, std::string & s)
{
std::ostringstream os;
os << object;
s = os.str();
}
This version avoids copy by value of the argument and the string.
