我正在尝试编写一个应用程序来 ping 一个 ip 地址并提供与 ping 相关的相关信息。虽然我遇到了很多错误，但我选择首先尝试并学习解决这个错误!我有一小段代码和一个包含编译器错误的单独文档。如果有人可以将此错误翻译成英文，那就太好了。我觉得如果我解决了底部的两个错误，很多其他错误可能会更容易查明。提前致谢。

最佳答案
这是你的问题:
#include <Windows.h>
#include <iphlpapi.h>
#include <icmpapi.h>
#include <string>
#include <winsock2.h>
您必须首先包含 winsock2.h，否则 windows.h 将包含 winsock.h。
尝试
#include <winsock2.h>
#include <Windows.h>
#include <iphlpapi.h>
#include <icmpapi.h>
