If not all members are required to exist at all times, you may want to consider using Lazy<T>.

Yeah, I've considered something akin to this approach. It's not the creation of them even that worries me so much but the population of them. I *can* do it on demand, for which Lazy here would be awesome, but I'm getting ahead of myself. As much as I know an operation like this is probably a pig, I want to wait to see before I implement demand population. I've stuck a pin in it mentally (and via some comments) but I want to see what the real world hit is going to be like. I have a low to middling PC to run it on, and plenty of test material to throw at it once it's ready.

When I was growin' up, I was the smartest kid I knew. Maybe that was just because I didn't know that many kids. All I know is now I feel the opposite.

I hope so. It gets instantiated a lot. I use it during code dom visitation, on any "marked" expression I need to "patch"

Basically, I'm using the CodeDOM as my abstract syntax tree to hold the results of my parse.

But without type information applied to it the tree is ambiguous. That is,

foo.bar.baz()

Could be a delegate invocation of field baz, or a delegate invocation of property baz.
foo could be a variable, a method argument, a type (where bar is a static field), an instance field, etc.

So for you to even know what to compile from this parse, you need to apply type information from the tree.

The CodeDOM has different objects for reference fields, properties, methods and events, plus arguments and variables. So when I parse, i plug the tree with "dummies" - foo is always treated as a variable until it's patched. xxx(...) always refers to a delegate invocation until it's patched.

While I patch, I "visit" each object in the CodeDOM tree, and look for these dummies I inserted. When I find one, I "get scope" which returns one of the monsters the partial code for is above.

I then use that data to match it against the names of each of the dummies I inserted - to see what's a field and what's a method and what's a property, and what's a type, etc. I then use this information to fixup the tree with the appropriate objects, creating compilable code.

Not much different than what the C# compiler does internally.

When I was growin' up, I was the smartest kid I knew. Maybe that was just because I didn't know that many kids. All I know is now I feel the opposite.

I've probably set the record for the amount of code I've written that nobody will use.

The latest in that category would be my CodeDomVisitor class, which does what it says - implements a visitor pattern over a CodeDom graph.

I thought about submitting a tip for it but then i figured, why bother? Who the hell would need something like this other than me? Laugh | :laugh:

TBF, it's one of those things you never need until you do, and then it's a godsend.
