In the vast majority of the cases there is no need for any optimization here, because just because memory is used, it does not mean that it can not be freed up during garbage collection. That means it is up for garbage collection, which will automatically occur when memory pressure becomes too high. When you have disposed your stream and it finally becomes dereferenced, it is called dead. Your memory is controlled by the garbage collector (GC). NET framwerk you don't have direct control over memory usage. I tried to clear byte array but found that it only replaces each element of array with 0 keeps its length same. What should be done to free up those space. Throw new Exception('Sorry we could not locate ' + userFileName) Īfter file is sent to response it doesn't free up the memory being taken. Throw new Exception('Sorry we can not serve ' + userFileName + ' file at this time.') Using (CryptoStream cs = new CryptoStream(fsInput, encryptor.CreateDecryptor(), CryptoStreamMode.Read)) Using (FileStream fsInput = new FileStream(inputFilePath, FileMode.Open)) Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(_password, _salt) public MemoryStream DecryptAndStoreInMemory(string inputFilePath, string userFileName) Decrypt a file and store in memory stream. Using (MemoryStream ms = DecryptAndStoreInMemory((path), userFileName))Ĭ = 'application/octet-stream' Ĭ('Content-Length', ()) Ĭ('Content-Disposition', 'attachment filename=' + userFileName) Ĭ(bytesInStream) Īrray.Clear(bytesInStream, 0, bytesInStream.Length)

DecryptAndStoreInMemory decrypt a requested file and store in memory As soon as file get downloaded I need to clear up all memory being used by that memory stream.

I have used memory stream to download the file.
