Exporting Grid Data to Excel and saving it in zip format

Question

Hi i'm working on asp net application. In this I need to Export Grid data to Excel and finally the excel file should be saved as zip file. I don't want to first save Excel file in some location then use zip functionality to fetch that file and convert it into Zip and save it. I want functionality which will directly convert Grid to Excel then Zip then finally saves it. I've seen so many forms and sites but none gave proper answer.

You can do this by dot.net Zip dll And following code will help you

gv.AllowPaging = false;
            Response.ClearContent();
            Response.AddHeader("content-disposition", "attachment; filename=" + strFileName);
            Response.ContentType = "application/zip";
            System.IO.StringWriter sw = new System.IO.StringWriter();
            HtmlTextWriter htw = new HtmlTextWriter(sw);
            gv.RenderControl(htw);
           // byte[] toBytes = Encoding.ASCII.GetBytes(somestring);
            MemoryStream stream = new MemoryStream();
             string attachment = sw.ToString();
             byte[] data = Encoding.ASCII.GetBytes(attachment);
                stream.Write(data, 0, data.Length);
                stream.Seek(0, SeekOrigin.Begin);   // <-- must do this after writing the stream!
           //   File.WriteAllBytes(@"D:\Saurabh\Testing\inputpdf\saurabhhtest.xls", stream.GetBuffer());



        using (ZipFile zipFile = new ZipFile())
        {
            zipFile.AddEntry("saurabhtest1.xls", stream);
            zipFile.Save(Response.OutputStream);
        }
