I'm trying to export my Asp.net core Grid content to excel format.

The samples that are available don't work because Response.OutputStream is not accessible in ASP.Net Core, so i've tried this:

private void SendForDownload(Workbook document, WorkbookFormat excelFormat)
{
string documentFileNameRoot;
documentFileNameRoot = string.Format("Document.{0}", excelFormat == WorkbookFormat.Excel97To2003 ? "xls" : "xlsx");

Response.Clear();
Response.Headers.Add("content-disposition", "attachment; filename=" + documentFileNameRoot);
Response.ContentType = "application/octet-stream";
document.SetCurrentFormat(excelFormat);
document.Save(Response.Body);

base.File(Response.Body, "application/octet-stream");
}

However, it's not creating the file for download. Has anyone accomplished this in Asp.Net Core?

The Workbook is being populated properly, just nothing happens when it attempts the save.
