Re: [Mono-list] Extension method not found
Ok thanks, adding System.Core in projectB fixed it. It worked without it with VS2010 though. Btw I was using a project reference not an assembly reference. -- View this message in context: http://mono.1490590.n4.nabble.com/Extension-method-not-found-tp2402574p2403419.html Sent from the Mono - General mailing list archive at Nabble.com. ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list
Re: [Mono-list] Extension method not found
Hello, Mr. Prawdi, hello list.
We have the same problem. We are side-stepping the assembly right now,
because we have others to get running under Mono. I had planned to boil it down
to a small piece of code and submit this to the list.
Same deal as yours - a whole bunch of extension methods work fine, but
there's just one that the linker can't seem to find.
Works fine on Windows-Mono, but fails on Linux-Mono (Suse). Windows-Mono is
built with MonoDevelop. Reflector reveals that the code looks fine.
I'll be tracking progress on this eagerly. I'll report anything I find out
when I get back to look at this. Please keep me advised if you find out
anything.
Cheers!

Hello,
I am having a weird problem with Mono. I have a solution made of 2 projects
A and B, targeting Mono/.NET 3.5. In project A, I have a class called
BinaryExtensions which define a bunch of extensions methods for
System.IO.BinaryReader and BinaryWriter. Both projects A and B use some of
these extensions methods; project B references project A for that reason.
For some reason, project B fails to find one of the extensions methods when
compiling.
The whole thing works perfectly fine under VS2010. Using Monodevelop 2.4
under Ubuntu 10.04 to compile my code, however, I get CS1061 (Type
'System.IO.BinayReader' does not contain a definition for funcX and no
extension method could be found). The thing is, the method in question is
used successfully by project A. Project B also successfully uses other
extensions methods from BinaryExtensions. But it fails to find one
particular function. Here is the code for that function:
public static string ReadNullTerminatedASCIIString(this BinaryReader
binaryReader, int count) {
var rawBytes = binaryReader.ReadBytes(count);
rawBytes = rawBytes.TakeWhile(b = b != 0x00).ToArray();
var chars = Encoding.ASCII.GetChars(rawBytes);
return new string(chars);
}
Again, this function is used by projectA and projectA compiles fine. Also,
other extension methods of that class are used by projectB and generate no
errors.
Also, when I use the assembly browser to check projectA, all extensions
methods decompile fine except for the method in question. I get:

Re: [Mono-list] Extension method not found
I want to correct something I just said. ProjectB did not use any other extension methods. I tried using another one and got the same error. So I am unable to use any extension method from ProjectA in ProjectB (although ProjectA uses them without issues). However, the decompilation error only happens with the method I listed; other extension methods decompile fine. -- View this message in context: http://mono.1490590.n4.nabble.com/Extension-method-not-found-tp2402574p2402578.html Sent from the Mono - General mailing list archive at Nabble.com. ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list

If not, check if ProjectB references System.Core. If it does not then this may be the cause of your compilation errors, since the attribute that designates a method as an extension method is declared in System.Core. (The this syntax for declaring extension methods is actually just syntactic sugar for the application of this attribute.) If you can compile under VS without referencing System.Core then this could be considered a Mono bug. And, as a final note, if this doesn't work, or if you are already referencing System.Core, then try to create a solution that reproduces the problem with minimal code. It's a bit hard to assist without having something we can tinker with and try to fix. -- Chris Howie http://www.chrishowie.com http://en.wikipedia.org/wiki/User:Crazycomputers If you correspond with me on a regular basis, please read this document: http://www.chrishowie.com/email-preferences/ PGP fingerprint: 2B7A B280 8B12 21CC 260A DF65 6FCE 505A CF83 38F5 IMPORTANT INFORMATION/DISCLAIMER This document should be read only by those persons to whom it is addressed.
