Command Line Arguments: How??

[Nigorr]

I have the following code. It is just the main part.
How do I use command line arguments to control which section of code is executed??

 
public static void Main(string[] args) { 
string fromDir; 
DateTime startTime = DateTime.Now; 
Console.WriteLine("Copy SCO files from CDSWEB to local Tomcat folder"); 

//Do this with -lib 
startInt = 39; 
fromDir = "F:\\Jdev9i_conf\\mywork\\SCO\\SCO_Main\\lib"; 
toDir = "C:\\Java\\Apache\\Tomcat\\webapps\\sco\\WEB-INF\\lib\\"; 
ProcessDirectory(fromDir); 

//Do this with -html 
startInt = 47; 
fromDir = "F:\\Jdev9i_conf\\mywork\\SCO\\SCO_Main\\public_html"; 
toDir = "C:\\Java\\Apache\\Tomcat\\webapps\\sco\\"; 
ProcessDirectory(fromDir); 

//Do this with -class 
startInt = 43; 
fromDir = "F:\\Jdev9i_conf\\mywork\\SCO\\SCO_Main\\classes"; 
toDir = "C:\\Java\\Apache\\Tomcat\\webapps\\sco\\WEB-INF\\classes\\"; 
onlyFileType = ".class"; 
excludeFolder = ".jsps"; 
ProcessDirectory(fromDir); 

}
