What are the benefits of following this rule even if I am not wrapping an unmanaged resource,

public class HasDisposeMethod
{
      public HasDisposeMethod()
      {
      }
      public void UseFileStream()
      {
         using(FileStream newFile = new FileStream(@"c:\temp.txt", FileMode.Open))
