Send List of string using ajax on mvc controller

  var stringArray = new Array();
// or var stringArray=[];
 stringArray.push('1');
 stringArray.push('2');

var data = JSON.stringify({
                'AllRecord': stringArray
            });

 $.ajax({
                url: 'url',
                cache: false,
                traditional: true,
                type: 'POST',
                contentType: 'application/json; charset=utf-8',
                data: data,
