How to sniff local outgoing network traffic in .NET without using PCap?

I'd like to somehow hook into the local system's network stack开发者_StackOverflow社区 to capture outgoing network packets without using Winpcap. Unfortunately it tends to crash my system every now and then.

Is there a way to "sniff" outgoing traffic of the local system from a user space process written in a .NET language?

What you want is the Network Monitor API. More here and here.

I use smsniff from NIRSOFT. You need to be admin on the machine to sniff any traffic.

I have never seen .net used to sniff traffic. But maybe NetMon from Microsoft has a COM interface you call from .Net

But as always you need to be admin to sniff traffic, since it is needed to put the NIC in promiscuous mode.
