https://bugzilla.novell.com/show_bug.cgi?id=659038#c0 Summary: Internal compiler error: Cannot cast from source type to destination type Classification: Mono Product: Mono: Runtime Version: 2.8.x Platform: Other URL: http://pastebin.com/raw.php?i=mXDQDvYX OS/Version: Mac OS X 10.3 Status: NEW Severity: Major Priority: P5 - None Component: generics AssignedTo: [email protected] ReportedBy: [email protected] QAContact: [email protected] Found By: Development Blocker: --- Description of Problem: The code compiles well under .NET 3.5 but fails to compile under Mono 2.8 (OSX running in VirtualBox). There is something wrong with resolving of correct this[...] property in base interfaces. To reproduce the problem compile the code below: using System.Collections; using System.Collections.Generic; namespace MonoBug { public interface IArray : IList { object this[params int[] index] { get; set; } } public interface IArray<T> : IArray, IList<T> { new T this[params int[] index] { get; set; } } public class Class1<T> : List<T>, IArray<T> { IArray<T> Source { get { return null; } } /// <summary> /// BUG: compiles on Windows but generates error under Mono (OSX) /// /// error CS0584: Internal compiler error: Cannot cast from source type to destination type. /// error CS0266: Cannot implicitly convert type `object' to `T'. An explicit conversion exists (are you missing a cast?) /// </summary> /// <param name="index"></param> /// <returns></returns> T IList<T>.this[int index] { get { return Source[index]; } set { Source[index] = value; } } object IArray.this[params int[] index] { get { return null; } set { } } public T this[params int[] index] { get { return default(T); } set { } } } } -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
