JQuery Array in Ajax post seems to serialise and appear as one element in controller list/array -

i have array in jquery holds id & value of attributes need pass mvc controller. array seems populate correctly in jquery , ajax post controller works too. however, value being passed controller appears flat single element in controller array (i.e. array values flattened 1 sequential string value).

here jquery:

    var attlistarray = new array();      table.find('tr').each(function (i, el) {         var tds = $(this).find('td'),             attname = tds.eq(0).text(),             attvalue = tds.eq(1).text(),             attid = tds.eq(2).text();          attlistarray[i] = attid + '~' + attvalue;         alert(attlistarray[i] + ' - ' + i);      });      $.ajax({         type: "post",         async: true,         contenttype: "application/json;charset=utf-8",         url: "@url.action("saveform", "home")",         data: '{"parms":"' + formelements + '" , "attlist":"' + attlistarray + '"}' ,         datatype: "json",         traditional: true,         success: function (data) {             alert("success");          },         error: function () {             alert("an error has occurred");          }     }); 

the controller action is:

    public jsonresult saveform(string parms, list<string> attlist)     {         models.result result = new models.result(false, "none");          namevaluecollection qscoll = httputility.parsequerystring(parms);          string s1 = "";          string s2 = "";          foreach (string s in qscoll.allkeys)         {             s1 = s1 + " , " + s;             s2 = s2 + " , " + qscoll[s];             //console.writeline("   {0,-10} {1}", s, qscoll[s]);         }          try         {             result.success = true;         }         catch (exception ex)         {             result.success = false;             result.error = ex.message;             //log event log             //drs_repository.logevent(ex.message, ex.source);         }          return json(result, jsonrequestbehavior.allowget);     } 

as example, have 2 strings in 2 array cells: [0] = '56~z', [1] = '59~x'. when array passed controller, list attlist contains 1 count of string = '56~z,59~x'. expecting array have count of 2 & elements passed list or array separate elements:

e.g. attlist[0]="56~z" , attlist[1]="59~x"

but can't result. i've tried passing string[] attlist, i've tried adding square & curly brackets around array in jquery , i've tried json.stringify array can't array pass list/array controller.

could explain i'm going wrong?

thanks in advance.

you can't concantenate strings , arrays, it's suprising if don't [object, object] on server?

as attlistarray array, should replacing line

data: '{"parms":"' + formelements + '" , "attlist":"' + attlistarray + '"}' , 

with

data: {parms : formelements, attlist: attlistarray}, 

as jquery accepts objects directly
