Summary: TypeBuilder: TypeLoadException is not reported when
interface implementation is missing
Product: Mono: Class Libraries
Version: SVN
Platform: All
OS/Version: All
Status: NEW
Severity: Normal
Priority: P5 - None

Currently, TypeBuilder.CreateType does not throw a TypeLoadException when one
of its methods - which implements an interface method - does not have a body.
To reproduce, compile and run the following code:
using System;
using System.Reflection;
using System.Reflection.Emit;
class Program
{
static void Main ()
{
AssemblyName assemblyName = new AssemblyName ();
assemblyName.Name = "lib";
AssemblyBuilder ab =
AppDomain.CurrentDomain.DefineDynamicAssembly (
assemblyName, AssemblyBuilderAccess.RunAndSave,
AppDomain.CurrentDomain.BaseDirectory);
ModuleBuilder mb = ab.DefineDynamicModule ("lib.dll");
TypeBuilder tb = mb.DefineType ("TheType",
TypeAttributes.Public,
typeof (object), new Type [] { typeof (IRunner) });
tb.CreateType ();
}
}
public interface IRunner
{
void Create (int interval);
}
Expected result:
Unhandled Exception: System.TypeLoadException: Method 'Create' in type
'TheType'
from assembly 'lib, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'
does
not have an implementation.
at System.Reflection.Emit.TypeBuilder._TermCreateClass(Int32 handle, Module
m
odule)
at System.Reflection.Emit.TypeBuilder.CreateTypeNoLock()
at System.Reflection.Emit.TypeBuilder.CreateType()
at Program.Main()
Actual result:
Successful completion.
