sort函数参数排序问题

Question

代码为：
struct compHCodeID
{
public:
bool operator()(DataStruct& _X,DataStruct& _Y)
{
return _X.strCodeID<_Y.strCodeID;
}
};
std::list m_sortDataList; //历史排序链表
m_sortDataList.sort(compHCodeID().operator());

报错为：error C2664: 'void __thiscall std::list<struct std::tagDATASTRUCT,class std::allocator<struct std::tagDATASTRUCT> >::sort(struct std::greater<struct std::tagDATASTRUCT>)' : cannot convert paramete

r 1 from 'bool (struct std::tagDATASTRUCT &,struct std::tagDATASTRUCT &)' to 'struct std::greater'

Answer 1

你还要实现compHCodeID结构体的

 operator <
