C# Implementation of the File Copy Command

<source lang="csharp"> using System; using System.IO;

 class Class1 {
   static void Main(string[] args) {
     string [] cla  = Environment.GetCommandLineArgs();
     if (cla.GetUpperBound(0) == 2) {
       FileInfo fi = new FileInfo(cla[1]);
       fi.CopyTo(cla[2],true);
       Console.WriteLine("Copied " + fi.Length + " bytes.");
     }
     else{
       Console.WriteLine ("Usage: cp <input file> <output file>");
     }
   }
 }

     if (cla.GetUpperBound(0) == 2)
     {
       FileInfo fi = new FileInfo(cla[1]);
       fi.MoveTo(cla[2]);
       Console.WriteLine("File Created : " + fi.CreationTime.ToString());
       Console.WriteLine("Moved to     : " + cla[2]);

     string [] cla  = Environment.GetCommandLineArgs();
     if (cla.GetUpperBound(0) == 1)
     {
       FileInfo fi = new FileInfo(cla[1]);
       fi.Delete();
       Console.WriteLine("File      : " + cla[1]);
       Console.WriteLine("Attributes: " + fi.Attributes.ToString());
       Console.WriteLine("File Deleted...");
     }
     else
       Console.WriteLine ("Usage: rm <filename>");
