C  supports two boolean or operators  the single bar   and the double-bar      The difference is that   always checks both the left and right conditions  while    only checks the right-side condition if it s necessary  if the left side evaluates to false    This is significant when the condition on the right-side involves processing or results in side effects   For example  if your ErrorDumpWriter Close method took a while to complete or changed something s state

Also worth mentioning  in C  the OR operator is short-circuiting  In your example  Close seems to be a property  but if it were a method  it s worth noting that   if  ActionsLogWriter Close      ErrorDumpWriter Close      is fundamentally different from  if  ErrorDumpWriter Close      ActionsLogWriter Close      In C   if the first expression returns true  the second expression will not be evaluated at all  Just be aware of this  It actually works to your advantage most of the time

The single       operator will evaluate both sides of the expression       if  ActionsLogWriter Close   ErrorDumpWriter Close    true           Do stuff here     The double operator        will only evaluate the left side if the expression returns true       if  ActionsLogWriter Close    ErrorDumpWriter Close    true           Do stuff here     C  has many similarities to C   but their still are differences between the two languages
