I want to do a real time monitor of the DNS cache requests of the system in c#. My system is a windows 7 64 bit. What I did so far is to catch the DNS requests by creating a listening UDP server on port 53, but this monitors ALL the DNS request, what I am interested in are only request made to DNS cache of the local OS. Is there a way to monitor the DNS cache of the system? THx

此 SO帖子说明了如何从C#调用powershell函数.

And this SO post illustrates how to call powershell functions from C#.
