Re: [DOTNET-ROTOR] Reflection.Emit bugs

[John Norwood]

Thanks for the bug report.  We've sent this along to the .NET team that
owns Reflection.Emit and they've confirmed these are bugs and are
entering them for tracking.

Subject: Reflection.Emit bugs


Hello,

While building my JVM for .NET (http://radio.weblogs.com/0109845/) I ran
into the following CLR bug. When ModuleBuilder.GetType(string) is used
to construct an array type from an unfinished type (as suggested in
ms-help://MS.NETFrameworkSDK/cpref/html/frlrfSystemReflectionEmitTypeBui
lderClassTopic.htm), it returns a different Type instance for each
invocation. Also, GetElementType() doesn't seem to work on these types.

Here is the source:
>>>>>>>>
using System;
using System.Reflection;
using System.Reflection.Emit;

class Bug
{
        public static void Main()
        {
                AssemblyName name = new AssemblyName();
                name.Name = "MyDynamicAssembly";
                AssemblyBuilder assemblyBuilder =
AppDomain.CurrentDomain.DefineDynamicAssembly(name,
AssemblyBuilderAccess.Run);
                ModuleBuilder moduleBuilder =
assemblyBuilder.DefineDynamicModule("MyDynamicModule");

                TypeBuilder lazyType =
moduleBuilder.DefineType("LazyType");

                Type t1 = moduleBuilder.GetType("LazyType[]");
                Type t2 = moduleBuilder.GetType("LazyType[]");
                Console.WriteLine(t1 == t2);
                Console.WriteLine(t1.Equals(t2));

                Type t3 = moduleBuilder.GetType("LazyType[][]");
                Console.WriteLine(t1);
                Console.WriteLine(t3.GetElementType());
                Console.WriteLine(t3.GetElementType() == t1);

                t1 = Type.GetType("System.Object[]");
                t3 = Type.GetType("System.Object[][]");
                Console.WriteLine(t1);
                Console.WriteLine(t3.GetElementType());
                Console.WriteLine(t3.GetElementType() == t1);
        }
}
<<<<<<<<<

Expected output:
True
True
LazyType[]
LazyType[]
True
System.Object[]
System.Object[]
True

Actual output (both on Rotor and the CLR):
False
False
LazyType[]
LazyType[][]
False
System.Object[]
System.Object[]
True

If someone from Microsoft could please confirm, and also forward this to
the CLR team, that would be great.

Regards,
Jeroen
