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;
}
