contextmenu - C# : getting folder name when right click on it -

i developing windows application, need folder name while right clicking on folder operations on .

so far did following :

1. made registry subkey in hkkey_class_root\folder\shell\(my program name)
2. made registry subkey of program name\command [the path of program]

now made registry key displayed in folder context menu. , in application did following :

1- in program.cs

    static void main(string[] args)     {         application.enablevisualstyles();         application.setcompatibletextrenderingdefault(false);         form1 p = new form1();         if (args.length > 0)         {             p.pathkey = args[0];         }         application.run(p);     } 

2- in form1 :

    private string _pathkey;     public string pathkey     {         { return _pathkey; }         set { _pathkey = value; }     }      private void form1_load(object sender, eventargs e)     {          if (this.pathkey != null)         {            textbox1.text=pathkey;         }     } 

finally :

now when right click on folder lets example called new. textbox3.text = c:\new , far works fine if folder name new folder textbox3.text = c:\new not c:\new folder , problem if args.length > 0 display the lenght 0 not full path.

you need put %0 in registry in quotes force entire path treated single argument.
otherwise, spaces treated argument separators.

you call string.join(" ", args) manually recombine of arguments, first way better.
