ArgumentNullException

ArgumentNullException


The exception that is thrown when a null reference is passed to a method that does not accept it as a valid argument.


Remarks

ArgumentNullException is thrown in cases where an object reference is Nothing and is required, or an Array is unitialized and is required.

ArgumentNullException works the same as ArgumentException and provides no additional functionality. This exception is used to distinguish Null reference exceptions from other argument exceptions.

ArgumentNullException uses the HResult E_POINTER, which is &H5B.
