ArgumentNullException vs ArgumentException

  • Article

Both ArgumentNullException and ArgumentException have a constructor which takes two strings.  One is the name of the parameter (or argument) in question and the other is a string describing the exception.

The funny/odd/interesting thing about them is that one has the opposite order of arguments.

For ArgumentException the constructor is:

    1: public ArgumentException(

    2:     string message,

    3:     string paramName

    4: )

 

While for ArgumentNullException is it:

    1: public ArgumentNullException(

    2:     string paramName,

    3:     string message

    4: )

 

And my point is....

Well, I don't have one I just thought it was an interesting thing to point out :)
