Accessing .NET private members

I just noticed a book review[^] on slashdot regarding techniques that allow you to access private members of classes. Anyone here know or has heard anything about this? Thought it was interesting, not sure how big a deal it is, though the book review seems to imply that it is not very difficult to do at all. Seems weird. ¡El diablo está en mis pantalones! ¡Mire, mire! Real Mentats use only 100% pure, unfooled around with Sapho Juice(tm)!
I really like the:
#define private public
#define protected publicway of doing it in C++... does this work.. can't try it here. Regards, Brian Dela :-)

In fact, IMHO, it is an abomination. But if .NET allows you to do this, I bet you can do it through Reflection or through IL. For, e.g., a field, maybe through reflection, using a FieldInfo object, you could set/get a field value. If this doesn’t work, I bet the ldfield/ldsfield opcode would do the trick.

this guy? You've never heard of Dan Appleman? Pretty big in the vb world. He's written a pretty good whitepaper (and book too) on regex.

It is done through reflection... But you also need to give your code the rights to query for private members... Use the "Administrative Tools/Microsoft .NET Framework Configuration" utility to create permission sets and assign them to code groups (assemblies) When running your code from the VS.NET IDE you might actually have those rights, even though your code don't have those right when run as standalone. I dunno why this is, but one should keep it in mind when developing/using this ability... Even though one would expect privates to remain private whatsoever, this feature can come in quite handy when it comes to creating your own generic classes for serialization/deserialization. (Been there, done that...)

I consider it rude, not to mention an invasion of privacy, to access anyone's private members on the 'net. There oughtta be a law!:mad:

It's obvious that they haven't spent all that much time with .NET. They're going at it a completely roundabout way. You can do it very easily through Reflection.

Reflection allows you to easily list the members of a class (even private) but can you actually call those members easily? cheers, Chris Maunder

The comments under this are truly great: "OMG .NET sucks and is so secure. Perl is SO much better because you can do this anyway. Man - Microsoft really screwed up letting this bug through QA. Lucky that Java sandboxes everything so you can't do this so it's more secure. Blah blah blah blah blah". yaawwwwwwn cheers, Chris Maunder
