Question

why is the bitwise operator before variable name when declaring this

Ping ^pingSender = gcnew Ping;

Thanks

Answer 1

You are talking about this code??

Ping ^ pingSender = gcnew Ping;

// When the PingCompleted event is raised, 
// the PingCompletedCallback method is called.
pingSender->PingCompleted += gcnew PingCompletedEventHandler( PingCompletedCallback );

Here this implies instance of ping class will be created from System.Net.NetworkInformation::Ping. Simply, this is not XOR operation but syntax of declaring object of managed type in microsoft implementation of C++ for .NET.
