maximum number of methods supported in C# class

[Colin Angus Mackay]

Where does that article answer the OP's question? Or did you just chuck some keywords in to Google and hit "I'm feeling lucky"?

Thanks for Info, But I read in one article that E-Bay once hits the compiler limit in max number of methods in single class. Thanks, Vythees

I just had a search through MS's C# Comiler errors/warnings list http://msdn2.microsoft.com/en-us/library/ms228373(VS.80).aspx[^] and can't see anything that explicitly complains about too many methods being in a class.

Seeing Assembly metatokens takes the following form: 00 000000, where the former is the type, and the latter is the code, I would say the maximum number of methoddef's in an assembly would be limited to 24-bits, iow 16.7 million. Dunno if there is a limitation on a classes though.

I think that if you ever reached that limit then you might want to seriously reconsider your design.

or the switch/case limit or the if/elseif limit or the .... or if none of that makes sense to you try this[^]

A nice research. Thanks, Vythees

IIRC ebay is running its servers using c++ and ISAPI, not .net.

Fiction : :) I may end up with Portablity issues with 32bit cousins. Not an real issue, but just to know the number. :wtf: Thanks, Vythees

[vytheese]

I agree, I think then there should be the same constraint exist in .NET class also. Thanks, Vythees

[vytheese]

Oh God, thats classic link. :) Thanks, Vythees

There is a limit, I remember someone a while ago (I've got a feeling in this forum) hit a limit on the number of fields in anycase that they could include in a class.  Buggered if I can remember where it was or what it was :sigh:

Not research, I know it from working with the spec :) And those values can be accessed from .NET 2 (nowadays).

Maybe you are thinking about the parameter limit, that is 16383/4.

No, I'm pretty sure that someone managed to hit a limit on the number of fields that could be contained in a class.  I'll do some digging.

I let this run for an hour to get to 5000 before I gave up. Someone with more CPU and physical RAM than I have should run it and see where it ends...

No wonder, always use StringBuilder for string concatenation in a loop.

Even assuming there is a constraint, you're talking about 2 totally different languages so why should they be the same?

Cannot been said to often! Good answere!

[PIEBALDconsult]

Well it can be said too often, but it's appropriate here.
