// Helper method within the Program class.

ShowEnvironmentDetails();

Console.ReadLine();

return -1;

}

Implement this method within your Program class to call various members of the Environment

type. For example:

static void ShowEnvironmentDetails()

{

// Print out the drives on this machine,

// and other interesting details.

foreach (string drive in Environment.GetLogicalDrives())

Console.WriteLine("Drive: {0}", drive);

Console.WriteLine("OS: {0}", Environment.OSVersion);

Console.WriteLine("Number of processors: {0}",

Environment.ProcessorCount);

Console.WriteLine(".NET Version: {0}",

Environment.Version);

}

Figure 3-4 shows a possible test run of invoking this method (if you did not specify command-

line arguments via Visual Studio 2008’s Debug tab, you will not find them printed to the console).

Displaying system environment variables

The Environment type defines members other than those shown in the previous example.

Table 3-1 documents some additional properties of interest; however, be sure to check out the

.NET Framework 3.5 SDK documentation for full details.
