如何使用特定网络接口（或特定源IP地址）进行Ping？
根据这个链接： 使用System.Net.NetworkInformation，有没有办法将ping绑定到特定的接口？ ICMP不能绑定到网络接口（与基于套接字的东西不同）：
ICMP不是基于套接字的。 ping将根据路由表发送到适当的端口。 https://stackoverflow.com/editing-help
但我看不出任何正确的方法来获取有关“pinger”的信息。 至少，在shell命令中，我可以指定源IP地址，但不能在我使用Ping类时。
我尝试以编程方式执行一些traceroutes以获取Ping路由中涉及的IP地址，但我没有得到网络接口的IP地址（我想它来自我无法将TTL设置为0的事实）。
有关如何确定哪个网络接口用于某个ping的任何想法？ （或指定用于ping的网络接口的方法）。
i know this is a old question but i found a solution and want to share it. 我在CodeProject上发布了这里的链接： http ： //www.codeproject.com/Questions/828234/Ping-over-specific-Interface-with-IcmpSendEchoEx? loginkey=false
编辑：
因此解决方案是在Iphlpapi.dll中使用IcmpSendEcho2Ex函数。
此函数使用接口ipaddress来确定应该在哪个接口上发送ping。
该链接包括p调用和包装函数输出的回复类。
