Here's one possible solution to your problemNote: I haven't tested this code so it might need some little tweaks. public ActionResult ExportFile(string[] years, string[] months, string[] radio, string[] acctNum) {Statement theStatementPath = new Statement();var thePath = theStatementPath.statementPath;List allPaths = new List();if (years != null){using (var db = new dbentities()){// we will store the contents of the zip file in memory, // just be careful if you have too many files you might run out of memoryusing (var memoryStream = new MemoryStream()){// create a zip archive and pass the memory as a parameter// you dont need a path, cause as like I said the zip will be in memoryusing (var zip = new ZipArchive(memoryStream, ZipArchiveMode.Create, true)){foreach (var aYear in years){List paths = db.Statement.Where(x => x.statementYear == aYear).Select(y => y.statementPath).ToList();// iterate all the paths for a given yearforeach (var path in paths){// check if the file at the path existsif (File.Exists(path)){// load the file into the zip archivezip.CreateEntryFromFile(path, path);}}}// once you iterate all years, return the zip file to browserreturn File(zip, "application/zip", "pdfs.zip");}}}} } hope this helps
