using native C code in a C# application

[manu.kanwarpal]

Hi,
Our team is working on a network monitoring tool. We have identified
"WINPCAP" as the library that provides support for packet capturing.
WINPCAP is made for WIN32 applications and is coded in 'C' language. We
intend to use this library on C# platform. If anyone has an idea or
experience(.. using native C code in a C# application), then please
help.

Warm Regards

Assuming you have exported your functions from WINPCAP.dll, you can make
the calls using the P/Invoke layer.

For a good starting point, check out the section of the .NET framework
documentation titled "Consuming Unmanaged DLL Functions", located at (watch
for line wrap):

Hope this helps.

Manu,
If you search on codeproject.com, I remember seeing at least one "Feature
complete" implementation of a managed code C# wrapper for WinPCap. Could save
you a lot of time.
