The reason for that is that computer programs have always workd that way since before Windows. Unix programs worked that way since before DOS. It is just the way that computer programs work. Windows GUI programs usually do not use command line arguments but text-based command (console) windows usually do. The C# and Java languages are designed based on the C++ language and C++ is an improvment of C. When C was designed all programs were command-line style of programs and C++ continues to use command-line arguments and C# is desgned based on C++. It is just the way it works; you don't really need to know why. Or did I miss something? Is there any reason you need to know why?

If you need to access the command line arguments passed to an application from anywhere else apart from the Main method, then you can do so with this line: string[] args = System.Environment.GetCommandLineArgs(); Notice though that, when you use this method, args[0] is always the file name of the executable itself and args[1] is the first command line argument, if there is one. Consequently, the array can never be empty. This isn't the case with the args parameter to the Main() method where args[0] is always the first command line argument, if there is one, and the array is empty if there are none.
