Take advantage of the null coalescing operator:В ?В orВ If()В . If you have known that a method can be null but it never should be during the development, then you can choose to use the Debug.Assert() to break as soon as possible when it does occur.ДҐ. UseВ Debug.AssertВ if a value should never beВ null, to catch the problem earlier than the exception occurs. In this measure, you can choose to throw a custom exception, only to catch it in the calling codes.Д¤. Explicitly check forВ nullВ from method calls and throw a custom exception. In order to avoid object reference not set to an instance of an object, you can choose to check for the null and provide a default value.ДЈ. Explicitly check for null and provide a default value.
