Answer 1

You are passing an xls (Excel) file as a text/csv. If you want to upload as xls, use

entry.MediaSource = new MediaFileSource("E:\\Emailcontent.xls", "text/csv");    

If you want to upload as xls, use

entry.MediaSource = new MediaFileSource("E:\\Emailcontent.xls", "application/vnd.ms-excel");
