.NET

I'm developing a home security application. One thing I'd like to do is automatically turn it off and on based on whether or not I'm at home. I have a phone with Wifi that automatically connects to my network when I'm home.

The phone connects and gets its address via DHCP. While I could configure it to use a static IP, I'd rather not. Is there any kind of 'Ping' or equivalent in C# / .Net that can take the MAC address of a device and tell me whether or not it's currently active on the network?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
