  I have a application for winfrom, always running ，the application include follow code:

  public class DataAccess
  {
    private static System.IO.FileSystemWatcher watcher ;
    public void TextCheck()
   {
     if (watcher == null)
     {
       watcher = new System.IO.FileSystemWatcher();
       watcher.Path = System.IO.Path.Combine (AppDomain.CurrentDomain.BaseDirectory);
       watcher.Filter = "*.txt";
       watcher.Changed += new System.IO.FileSystemEventHandler(watcher_Changed);
       watcher.IncludeSubdirectories = true;
       watcher.EnableRaisingEvents = true;
     }
   }
  }
  
  
  

  To sum up, we use code to monitor and control file for type of txt.

  then I have a question: the code always throw exception,details as follows

  System.OutOfMemoryException: the specified buffer size is too large,FileSystemWatcher Unable to allocate 8192 bytes internal buffer,     
  in System.IO.FileSystemWatcher.Monitor(IntPtr bufferPtr)     
  in System.IO.FileSystemWatcher.StartRaisingEvents()    
  in System.IO.FileSystemWatcher.set_EnableRaisingEvents(Boolean value)
