Hi there, my problem is the file is not writing to the client side nothing happening

my code is above:
            //Save the Excel spreadsheet to a MemoryStream and return it to the client
            using (var exportData = new MemoryStream())
                    string saveAsFileName = string.Format("ObrasNuevas-{0:d}.xls", DateTime.Now).Replace("/", "-");
                    Context.Response.ContentType = "application/";
                    Context.Response.AddHeader("Content-Disposition", string.Format("attachment;filename={0}", saveAsFileName));
                catch (Exception ex)

my server is Windows 2003 , only work with chrome but with ie i cant get the xls file

First off, I just wanted to point out that your issue is not with NPOI.

Next, looking at your code, I believe you may need to add the content size to the response header.

Try adding the following immediately after the addition of the Content-Disposition to the header:
Context.Response.AddHeader("Content-Length", exportData.Length.ToString());
If that doesn't solve your problem, try changing the Content-Type from application/ to application/octet-stream.
