Program Structure of C# .NET

Here is the basic program structure of C# .NET:

using System; 

namespace Hello {
   public class HelloWorld {
      public static void Main(string[] args) {
         string name = "C#";

         // See if an argument was passed from the command line
         if (args.Length == 1)
            name = args[0];

         Console.WriteLine("Hello, " + name + "!");
      }
   }
}
