Processing Command-Line Arguments

for Loop version

static int Main(string[] args)
{
...
  // Process any incoming args.
  for(int i = 0; i < args.Length; i++)
    Console.WriteLine("Arg: {0}", args[i])
 
  Console.ReadLine();
  return -1;
}

Foreach Version

// Notice you have no need to check the size of the array when using "foreach".
static int Main(string[] args)
{
...
  // Process any incoming args using foreach.
  foreach(string arg in args)
    Console.WriteLine("Arg: {0}", arg);
 
  Console.ReadLine();
  return -1;
}

GetCommandLineArgs() Version
namespace : System.Environment
return value: an array of strings
first index : identifies the name of the application itself

static int Main(string[] args) 
{ 
... 
  // Get arguments using System.Environment. 
  string[] theArgs = Environment.GetCommandLineArgs(); 
  foreach(string arg in theArgs) 
    Console.WriteLine("Arg: {0}", arg); 
 
  Console.ReadLine(); 
  return -1; 
} 

An Interesting Aside: Some Additional Members of the System.Environment Class

// 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);
