c# - Generate list of files in directory with relative path -

so, i'm making little app generates list of files inside folder (recursive) command line argument. generate file list relative paths can use them later. command argument folder c:/folder, want inside folder not including folder itself.

this now

c:/folder\some.exe   c:/folder\locales\en.pak   c:/folder\logs\client_2016.log 

this like.

some.exe   locales\en.pak   logs\client_2016.log 

code

public static void processdirectory(string targetdirectory)     {         // process list of files         string[] fileentries = directory.getfiles(targetdirectory);         parallel.foreach(fileentries, fileentry =>         {             processfile(fileentry);         });          // recurse subdirectories         string[] subdirectoryentries = directory.getdirectories(targetdirectory);         parallel.foreach(subdirectoryentries, subdirectoryentry =>         {             processdirectory(subdirectoryentry);         });     }      public static void processfile(string path)     {          //string output = path.replace(environment.getcommandlineargs, ""); maybe?         //console.writeline(output);         console.writeline(path);     } 

you don't need handle recursion yourself; can use overload of directory.enumeratefiles() takes searchoption parameter.

provided root starts drive letter or \\, can want this:

string root = @"d:\test\";  var files = directory.enumeratefiles(root, "*", searchoption.alldirectories)     .select(path => path.replace(root, ""));  // files contains file names want, root removed.  console.writeline(string.join("\n", files)); 

note file entries not fetched until enumerate them. can put them in list so:

var listoffiles = files.tolist(); 

or can use foreach iterate on them without putting them in list first.

foreach (var file in files) {     // file. }
