User [email protected] added comment https://bugzilla.novell.com/show_bug.cgi?id=463323#c13 --- Comment #13 from Amir Shimoni <[email protected]> 2009-02-10 14:49:22 MST --- In the process of trying to make the bug reproducible, I managed to discover another bug that belongs to this bug heading. Here is the code: using System; using System.Linq.Expressions; namespace MonoBug { class Program { public void testFunc() {} static void Main() { // the commented line doesn't have any problems... // Expression<System.Func<Program, Action>> action = (d => // (Action)Delegate.CreateDelegate(typeof(Action), d,"testFunc" )); Expression<System.Func<Program, Action>> action = (d => d.testFunc); var t = action.Compile(); Program p = new Program(); t(p); } } } It works with no problems on MS.net. It also works with delegates instead of the expression/compile() pair. But under the mono runtime, it creates this exception: Unhandled Exception: System.ArgumentException: method argument length mismatch at System.Delegate.CreateDelegate (System.Type,object,System.Reflection.MethodInfo,bool) [0x00266] in /mnt/photos1/dist/monosvn/mcs/class/corlib/System/Delegate.cs:259 at System.Delegate.CreateDelegate (System.Type,object,System.Reflection.MethodInfo) [0x00000] in /mnt/photos1/dist/monosvn/mcs/class/corlib/System/Delegate.cs:263 at (wrapper dynamic-method) System.Runtime.CompilerServices.ExecutionScope.lambda_method (System.Runtime.CompilerServices.ExecutionScope,MonoBug.Program) <IL 0x00015, 0x00079> at MonoBug.Program.Main () [0x000ac] in /tmp/test1/Program.cs:18 This is not the original bug, but is a "Bug with delegates to dynamic methods", that might be closely related, and/or could lead to the original bug. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
