No Effect. 1) The parameter of the Main method is a String array that represents the command-line arguments. 2) Command line arguments commonly get used when you need to pass information to your application at runtime. 3) For example if you were writing a program that copies a file from one location to another you would probably pass the two locations as command line arguments. For example: 4) Copy.exe C:\file1.txt C:\file2.txt

As far as you are not going to pass command line arguments, no need to write string[] args.
