Poll for a file in server path in c#

Sometimes we come across situations where we have to poll for a file availability in a server location.

Simple code to do it is given below :



 public  bool PollForFile(FileInfo file)
        {
            bool fileReady = false;
            while (!fileReady)
            {
                try
                {
                    //Check if file is not in use ..if it is in use then it cannot be opened,so exception will be thrown.
                    using (file.Open(FileMode.Open, FileAccess.ReadWrite, FileShare.None))
                    {
                        fileReady = true;
                        break;
                    }
                }
                catch (IOException)
                {
                    //File isn't ready yet, so we need to keep on waiting until it is.
                    fileReady = false;
                }

                //We'll want to wait a bit between polls, if the file isn't ready.
                if (!fileReady)
                {
                    Thread.Sleep(1000);
                }
            }

            return fileReady;
        }
