c# - asp.NET controller does not seem to be executing in proper order -

i using jquery file upload plugin , posting zip files controller. happening execution order cannot seem figure out. when set debug point @ top seems jump on place in controller , because of this, code not seem working think should.

here post:

$('#fileupload').fileupload({     url: '/fileupload/import',     add: function (e, data) {         var filesubmit = data.submit()             .success(function (result, textstatus, filesubmit) {                 var name = data.files[0].name;                 filevalidation(name, textstatus);              })             .error(function (filesubmit, textstatus, errorthrown) {                 var name = data.files[0].name;                 filevalidation(name, textstatus);             });                },     done: function (e, data) {         $.each(data.files, function(index, value){             if (value.name == "") {                 alert("error uploading: " + value.name + ". " + failstatus);             }             else              {                 $('#filesubmit').show();             }         });     } }); 

which seems firing off think would. post 1 file @ time shown here fiddler:

asp.net controller not seem executing in proper order , instead bounces on place. here controller:

[httppost] public actionresult import() {     list<zipcontents> filelist = new list<zipcontents>();     var r = "file uploaded.";      try     {                  if (session["session_import_storage"] != null)         {              filelist = (list<zipcontents>)session["session_import_storage"];         }          stream s = request.files[0].inputstream;         string fn = request.files[0].filename;         filelist.add(new zipcontents(s, fn));          session["session_import_storage"] = filelist;      }     catch     {         r = "an error occurred uploading file(s).";     }      return json(r); } 

what mean if set debug point at:

list<zipcontents> filelist = new list<zipcontents>(); 

and hover over: string fn = request.files[0].filename; says: "morexmlfiles.zip"

then hit f11 , moves next line. , again steps try. , again hits if statement.

if hit f11 again goes way original debug point , when hover on string fn = request.files[0].filename; again shows next file name already. code didn't finish first file...

does know going on here?! appreciated. thanks!
