$.ajax({     url: '@url.action("downloadfile", "home")',     type: 'post',     contenttype: "application/json",     data: json.stringify({ url: urllink}),     success: function(res) {      },     error: (function() {         alert("error retrieve selected report");     }) }); 

since looking working download file code, sharing use.

we have 2 call process download code. first call file prepared , saved on server. second call shown below read file content , return file object.

controller.cs:

    [httpget]     public actionresult downloadstream(string filename, int searchid)     {         var tempstore = _searchservice.gettempstore(searchid);         var bytes = tempstore.dataasblob;         if (bytes != null)         {             var stream = new memorystream(bytes);             _searchservice.deletetempstore(searchid);             return file(stream, "application/vnd.ms-excel", filename);         }          _logger.log("export/downloadstream request failed", logcategory.error);         return json("failed");     } 

view.cshtml

following line calls downloadstream method on server, server send file object gets save on user machine.

window.location = '/export/downloadstream?filename=' + result+"&searchid="+searchid;

    function exportdata(exporttype, exportformat) {          var searchid = document.getelementbyid('hfselecteddriverid').value;         var model = { searchid: searchid, exporttype: exporttype, exportformat: exportformat };          $.ajax({             url: '@url.action("exportdriverfile", "export")',             contenttype: 'application/json; charset=utf-8',             type: 'post',             datatype: 'html',             data: json.stringify(model)         })             .success(function (result) {                 result = result.tostring().replace(/"/gi, "");                 if (result == "" || result == "failed")                 {                     alert("file download failed. please try again!");                 }                 else                 {                     window.location = '/export/downloadstream?filename=' + result+"&searchid="+searchid;                 }             })         .error(function (xhr, status) {             //alert(status);         });     }
