I want to append the console output to an external file. Here's my code: //copy console output to file in bin\Debug folder class ConsoleCopy : IDisposable { FileStream fileStream; StreamWriter fileWriter; TextWriter doubleWriter; TextWriter oldOut; class DoubleWriter : TextWriter { TextWriter one; TextWriter two; public DoubleWriter(TextWriter one, TextWriter two) { this.one = one; this.two = two; } public override Encoding Encoding { get { return one.Encoding; } } //Clears all buffers for the current writer public override void Flush() { one.Flush(); two.Flush(); } public override void Write(char value) { **one.Write(value);**//error thrown here two.Write(value); } } public ConsoleCopy(string path) { oldOut = Console.Out; try { **//fileStream = File.Create(path);** //runs alright with this line fileWriter = new StreamWriter(fileStream); fileWriter.AutoFlush = true; doubleWriter = new DoubleWriter(fileWriter, oldOut); } catch (Exception e) { Console.WriteLine("Cannot open file for writing"); Console.WriteLine(e.Message); return; } Console.SetOut(dou

And why only http://stackoverflow.com/questions/29617289/filestream-cannot-access-closed-file on the server? up vote 0 down vote favorite I have a code snippet which uploads an image. On uploading, it temporarily stores the file in a Session. Then on click of "Save", it saves the file in a database. There's no problem on my machine, but on the server, whenever I try to upload some files, and then click on "Save", it shows me an error "Closed file http://stackoverflow.com/questions/11667745/why-does-cannot-access-closed-file-error-show-up-and-why-only-on-the-server cannot be accessed". On Googling it, I read here that this was due to large files being uploaded. I wanted to confirm, is the problem that I'm uploading large files?? Or could it be something else? Also, why am I not getting this on my machine and only on the server?? EDIT: By the way, the error showed up when the file size > 80kb Code on Uploading file: public ActionResult StoreLogoInSession(HttpPostedFileBase file, int assetID) { string filename = null; if (ValidateOnUpload(file)) { Session.Add("TempLogo", file); filename = file.FileName; Session.Add("filename", filename); } return RedirectToAction("Edit", new { id = assetID }); } Code on Saving (this is when the error occurs): public ActionResult SaveLogo(LogoModel m, int assetID) { HttpPostedFileBase file = (HttpPostedFileBase)Session["TempLogo"]; var logoModel = new LogoModel(); var asset = this.GenerateAssetForUploadFile(file, (int)m.Asset.AccountID, m.Asset.TextContents, m.Asset.AssetName); this.LogoManagementFacade.SaveLogo(asset); logoModel.Asset = asset; this.LogoModelList.Add(logoModel); } asp.net-mvc-3 file-upload share|improve this question asked Jul 26 '12 at 10:54 karan k 44911337 Using Session is bad. Using Session to store uploaded file is an abomination. Please don't. –Darin Dimitrov Jul 26 '12 at 11:11 okay, but what about this problem I'm facing now? –karan k Jul 26 '12 at 11:14 The problem you are facing is a design probl
