c# - Pass the file name of a saved file from one class to another -

i'll best explain.

my program takes screen shots user can save desktop or pass media server.

however, pass server first must have file location of image saving , must first save file using save file dialog , store location of in string triggers bool image has been save. code looks pass file server:

// sfd safe file dialog uploadtoserver.httpuploadfile(settings.default.serveraddress , sfd.filename.tostring(), "file", "image/jpeg", nvc); 

i tried store sfd in following way pass call class:

public string saveimagelocation {    { return sfd.filename.tostring(); }    set { sfd.filename.tostring() = value; } } 

but following error:

error 1 left-hand side of assignment must variable, property or indexer

what i'm trying achieve take file upload code , move class. can me error?

this method/function (call).

tostring() 

you cannot assign method/function (call) value..

.tostring() = value; 

try

public string saveimagelocation {   { return sfd.filename.tostring(); }   set { sfd.filename = value; } } 

please note have not indicated type filename is, still may not work.
