Default Using win 32 dll in C#

I have used the function InternetGetConnectedState() to check whether the system is connected to internet. It is working Correctly.
But the Function returns the description about the connection in its out parameter (here Description) how can i print that description.
i tried printing Value in Description but it prints number.
I tried Comparing it with Return Constants but it gives Error .
The Constant Name Is undefined.

[DllImport("wininet.dll")]
private extern static bool InternetGetConnectedState(out int Description, int ReservedValue ) ;

Hi Abhijeet

The value that is being retruned is of typ DWORD
and the numerical value stored in it is what you
are seeing when you print it. The right way is to check
the returned value against constants but instead of using
the constant names .Net check the values of these constants
in Wininet.h file and check the returned value against them.
Like the constant INTERNET_CONNECTION_LAN has the value 2
defined in Wininet.h.
