if I don't exist OR ....

codemunch

Found this C# beauty in 3 places in a particular class i'm updating. if (this == null || ..... { // assigned values to self } I'm guessing the person that wrote that was going to be checking a field to see if it was null but none of the assignment code within the {} indicates what that might have been.

maybe it's some philosophic-thing...

Sanity checking? ;P

The object might feel a bit of insecure and thus need to re-assure itself sometimes.

It's an AI piece of code - it's the equivalent to "I think therefore I am, you aren't me so you don't matter."

Deja View - the feeling that you've seen this post before.

AI is much clearer in VB, as in

    If (Me Is Nothing) Then
        ' I don't exist, so I can't think (straight? at all?)
    End If

OK, so you'd not want to assign a value to an object that was null, but it brings up an interesting discussion on the use of "if (this != null)". Take a look at this discussion on MSN[^] about this != null in C#.

not being fluent in VB.NET does that to people; I'm just a C# guy. :-D

if (this == null)
{
// I wasn't here; you never saw me
}

if (this == null || ..... { // assigned values to self } You can get into the true part there, you just have to do a bit of IL hacking. Since instance methods are like static methods with a "this" param as the first arg in il. you can invoke such method and pass null to "this" Im not saying you should do this, but its possible :-) I happened to get that problem when I was doing the subclass proxies for NAspect (our AOP framework) It works as long as you don't access any member variables :-P

I'm not fluent, and that doesn't make me feel inferior. Conclusion? I'm not people. Wow, that was easy ;) In case you missed it, I meant the language (not you) expresses its inferiority complex with "me is nothing"
