本文介绍了一种使用C++标准库中的std::ostringstream来高效拼接字符串的方法。通过实例展示了如何将不同类型的变量（如浮点数）转换为字符串，并将其拼接起来。这对于需要频繁生成复杂字符串的应用场景非常有用。

std::ostringstream   ostr;   //   include   <sstream>
ostr   <<   "targetBox.m_vMax("   <<   targetBox.m_vMax.x ;
ostr   <<   ","   <<   targetBox.m_vMax.y ;
ostr   <<   ","   <<   targetBox.m_vMax.z ;
ostr   << ")";

ostr   <<   "targetBox.m_vMin("   <<   targetBox.m_vMin.x ;
ostr   <<   ","   <<   targetBox.m_vMin.y ;
ostr   <<   ","   <<   targetBox.m_vMin.z ;
ostr   << ")";

ostr   <<   "m_vMax("   <<   m_vMax.x ;
ostr   <<   ","   <<   m_vMax.y ;
ostr   <<   ","   <<   m_vMax.z ;
ostr   << ")";

ostr   <<   "m_vMin("   <<   m_vMin.x ;
ostr   <<   ","   <<   m_vMin.y ;
ostr   <<   ","   <<   m_vMin.z ;
ostr   << ")";

//std::cout << ostr.str().c_str() << std::endl;

std::string s = ostr.str();
Logs::LogsWrite((TCHAR*)s.c_str(),"testCollionTest.txt");

离开了MFC一下子连怎么拼接字符串都不会了，从网上查到了用std::ostringstream可以实现，记录下来。
