Anjular code:

var getFileDownloadData = function (dictName, inputParams) {
var deferred = $q.defer();

$http({

debugger;

var octetStreamMime = 'application/octet-stream';
var success = false;

// Get the headers
headers = headers();

I'm trying to download pdf and doc files for now. They are able to download but cant be opened (like corrupt files).

Please help me where the issue is:

The following is the code in API controller:
--------------------------------------------
-> FileIOController

[HttpGet]
public HttpResponseMessage GetFileData([ModelBinder]List<string> inputparams)
{
var fileData = _fileUploadManager.GetFileData(3047);

if (fileData != null)
{
//return fileData;


HttpResponseMessage response = new HttpResponseMessage();
response.StatusCode = HttpStatusCode.OK;
response.Content = new ByteArrayContent(fileData.FileContent);
response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
{
FileName = fileData.FileName
};
response.Content.Headers.ContentLength = fileData.FileContent.Length;
response.Content.Headers.Add("x-filename", fileData.FileName);
return response;
}
}
