Download XML received from controller

I need to download an XML received from a controller, but I need the prompt to write a the name and the location where the file will be saved.
First question: is optimal to send the xml like I did in this code or I should send it like a file in some way.
Second question: receiving the xml or the xml file, how can open the prompt and finally save the xml like a file?
[HttpPost]
public ActionResult ExportFiles(string clientName, string currenthcsystem)
{
try
{
var systemActionsConfigurationData = service.GetHcSystemActionsConfigurationData(clientName,currenthcsystem);
XmlSerializer xsSubmit = new XmlSerializer(typeof(HcSystemActionsConfigurationData));
var xml = "";
using (var sww = new StringWriter())
{
using (XmlWriter writer = XmlWriter.Create(sww))
{
xsSubmit.Serialize(writer, systemActionsConfigurationData);
xml = sww.ToString();
}
}
return Content(xml, "text/xml");
}
catch (Exception)
{
throw;
}
}
$('#exportButton').on("click", function () {
var clientName = $(actionsButtons).data('clientname');
var currentHCSystem = $(actionsButtons).data('hcsystemname');
// Create FormData object
var parameters = new FormData();
parameters.append("clientName", clientName);
parameters.append("currentHCSystem", currentHCSystem);
$.ajax({
url: $(actionsButtons).data('export'),
type: 'POST',
data: parameters,
cache: false,
processData: false,
contentType: false,
success: function (response) {
//logic to open the prompt and finally download the xml
},
error: function (err) {
}
});
});

Access file using MVC 6 .NET Core with ajax

I am calling this function to send a file via post:
function AddFileHandler() {
return $.ajax({
processData: false,
contentType: false,
type: "POST",
url: '#Url.Action("AddFile", "SomeController")',
data: getFile()
})
}
In my controller, there is this method which produces an error on the first line:
[HttpPost]
public string AddFile()
{
var attachedFile = Request.Form.Files["CsvDoc"]; // there is an error of wrong contentType
return "";
}
My getFile method optains data like this:
function getFile() {
var input = document.getElementById("csvFile");
if (!input || !input.files || !input.files[0]) {
return ";";
}
console.log(input.files[0]); //inputs my file correctly
var data = new FormData();
data.append("CsvDoc", input.files[0]);
}
What exactly am I doing wrong? Does it matter what is in the html?

You're forgetting to return anything from getFile()
simply add
return data;

how to download file into aclient from server without Returning filepathresult

i saw this code for downloading a file into client from server...
public ActionResult Download()
{
string file = #"c:\someFolder\foo.xlsx";
string contentType = "application/pdf";
return File(file, controntType, Path.GetFileName(file));
}
But the problem is that i have to do two different things in this Download method.Atfirst ,i want to download the file and then i need to get path of downloaded file and pass in to a documentviewr to display it.so i wrote this code in view razor.
function navigate(target) {
$.ajax({
url: '#Url.Action("Download", "Patient")',
type: 'GET',
dataType: 'json',
cache: false,
data: { 'filepath' : target },
success: function (results) {
event.preventDefault();
documentViewr.loadDocument(results);
},
error: function () {
alert('Error occured');
}
});
}
and in my controller i wrote this:
[HttpGet]
public JsonResult Download(string filepath)
{
var content_type = "";
//path = Path.Combine("D:\file1", filename);
content_type = "application/pdf";
FilePathResult file = File(filepath, content_type,
Path.GetFileName(filepath));
String sDocID, sDocPath;
ViewerController vc = new ViewerController();
sDocPath = Server.MapPath(".") + "\\App_Data\\sample.docx";
sDocID = vc.LoadDocument(sDocPath);
return Json(sDocID, JsonRequestBehavior.AllowGet);
}
so my question is that how i can merge this two actions together?because if i do not return FilePathResult i can not download the file..my another question is that how i can define the path in which file will be downloded?can i tell it to download files into for example Server.MapPath(".") + "\App_Data\...??
i will be grateful if u can help me....

javascript ajax call not not hitting controller

I am trying to build up a list of mock files for Dropzone.js to consume. I have an MVC controller method defined as follows:
[HttpPost]
public async Task<JsonResult> GetImageInfo(int imageId)
{
//int imgId;
//int.TryParse(imageId, out imgId);
var image = await RepublikDb.PropertyImage.FindAsync(imageId);
var path = Server.MapPath(image.ImageURI);
var size = new FileInfo(path).Length;
var fileName = new FileInfo(path).Name;
var thumbnailURI = image.ThumbnailImage.ImageURI.TrimStart('~');
return Json(new { fileName = fileName, size = size, thumbnailURI = thumbnailURI });
}
I have tested this endpoint with Postman, and everything works as expected, however each time I try and get the data in JS, the server returns a 500 error code, with complaints of the following: Exception Details: System.ArgumentException: The parameters dictionary contains a null entry for parameter 'imageId' of non-nullable type 'System.Int32'
Here is the JS AJAX code:
//Entry point to JS from razor. A comma separated string is passed here. Eg. imageIds = "10,12,14,16"
EditFormInit("#Model.PropertyImageIds")
var EditFormInit = function (imageIds) {
var imageIdsArr = imageIds.split(",");
var imageFiles = [];
imageIdsArr.forEach(function (ImageId) {
var requestData = { imageId: parseInt(ImageId) };
//var reqUrl = "?imageId=";
//reqUrl = reqUrl.concat(requestData.imageId.toString());
$.ajax({
type: "POST",
url: "/Admin/PropertyImage/GetImageInfo",
data: requestData,
contentType: "text/json; charset=utf-8",
dataType: "json",
success: function (data, status, jqXHR) {
var image = { fileName: data.fileName, size: data.size, thumbnail: data.thumbnailURI }
imageFiles.push(image);
}
});
});

Try:
contentType: "application/json"
This should work

so i finally realised why the controller was not getting hit, and resolved that issue. The $.ajax was passing the controller a JSON request, which was obviously failing.Once I removed the offending lines, the controller breakpoint finally got hit.
$.ajax({
type: "POST",
url: "/Admin/PropertyImage/GetImageInfo",
data: requestData,
success: function (data, status, jqXHR) {
var image = { fileName: data.fileName, size: data.size, thumbnail: data.thumbnailURI }
imageFiles.push(image);
}}
);
Even though the response from the controller is now coming back, the imageFiles array is still null. What am I doing wrong here?

You don't need to stringfy uploaded image path. Below code is working in my application. I just used FormData() to get all form. After that added all items in form that i want to send to controller. In this case, you don't need to pass parameter in controller. You can get by Request.Files for image & Request.Form for extra data. I hope, It may helps you. If there is any wrong, then share with me, i will sort it out.
Java Script -
function AddRetailer()
{
try {
var storeName = $("#StoreName").val();
var storeUrl = $("#StoreURL").val();
var retailerLogoPath = $("#StoreLogo").val();
var ecommercePlatform = $("#EcommercePlatform").val();
var fileName = document.getElementById('fileUpload')..get(0).files;
var data = new FormData();
if (fileName.length > 0) {
data.append("userUploadedImage", fileName[0]);
data.append("storeName", storeName);
data.append("storeUrl", storeUrl);
data.append("ecommercePlatform", ecommercePlatform);
}
$.ajax({
url: $("#addRetailer").val(),
processData: false,
contentType: false,
type: "POST",
data: data,
success: function (data) {
},
error: function (resp) {
alert(resp);
}
});
}
catch (e) {
}}
Controller -
[HttpPost]
public string AddRetailer()
{
HttpPostedFileBase image = Request.Files["userUploadedImage"];
string storeName = Request.Form["storeName"];
string storeUrl = Request.Form["storeUrl"];
string ecommercePlatform = Request.Form["ecommercePlatform"];
}
