Check Internet connection

[C# Programming]

Hi! I' m using this sample to check if the machine is connected to Internet, but it gives me 3 errors. Why' s that?

Here is the sample:


using System;
using System.Runtime;
using System.Runtime.InteropServices;

class IsConnected
{
//Creating the extern function...
[DllImport("wininet.dll")]
private extern static bool InternetGetConnectedState(int out Description, int ReservedValue);

//Creating a function that uses the API function...
public static bool IsConnectedToInternet()
{
int Desc;

return InternetGetConnectedState(out Desc, 0);
}
}


Here are the errors:

Error 1: Identifier expected; 'out' is a keyword | Line: 9
Error 2: Invalid token ',' in class, struct, or interface member declaration | Line: 9
Error 3: ; expected | Line: 9
