c# - Pass arguments to running application -

i making image uploader (upload image image hosting website) , i'm having issues passing argument (image location running application)

• first of let's myapp.exe running
• whenever right click on image have added item in default windows context menu says "upload image".
• when that's clicked needs pass location running application.

my program.cs:

static class program {     [dllimport("user32.dll")]     static extern intptr findwindow(string lpclassname, string lpwindowname);      [dllimport("user32.dll")]     static extern intptr sendmessage(intptr hwnd, uint msg, uintptr     wparam, intptr lparam);      [dllimport("user32.dll", setlasterror = true, charset = charset.auto)]     static extern uint registerwindowmessage(string lpstring);      [stathread]     static void main(params string[] arguments)     {         if (arguments.length > 0)         {     //this means the upload item in context menu clicked     //here method "uploadimage(string location)"     //of running application must ran         }         else         {     //just start application             application.run(new controlpanel());         }     } } 

note controlpanel class doesn't have visible form, tray icon present since form not needed.

could on how this?
