Defining Destructor (Finalizer) and calling the base Filnalize??? how?

[esafran]

I've defined a class, but now I want to Define a Finalizer
(destructor)...

How do I call the Base Finalizer???, void Finalize() is a protected
override method and Type.GetType Does not work.

Hoe do I call it?

private void DefineFinalizer (TypeBuilder typeBuilder)
{
MethodBuilder finalizerMethod Builder = typeBuilder.Def ineMethod(
"Finalize",
MethodAttribute s.Family | MethodAttribute s.Virtual |
MethodAttribute s.HideBySig,
CallingConventi ons.Standard,
TYPE_VOID,
Type.EmptyTypes );

ILGenerator generator = finalizerMethod Builder.GetILGe nerator();

generator.Begin ExceptionBlock( );

generator.EmitW riteLine("Final ize was called");

generator.Begin FinallyBlock();

// Should call base Finalizer here...

generator.EndEx ceptionBlock();
generator.Emit( OpCodes.Ret);
}

Please I have to know how to call the base Finalize... otherwise, I
believe so, Lutz does not treat this method as destructor...

Eyal Safran.

I'm sorry I ment:

How do I call the Base Finalizer???, void Finalize() is a protected
override method and Type::GetMethod Does not work (only shows public)
and Type::GetMethod s also does not work.

Type::GetMethod s does not default to return non-public members, try
something like

type.GetMethod( "Finalize",Bind ingFlags.NonPub lic | BindingFlags.In stance);

which should do the job. You might have to add a few more BindingFlags, I
don't recall what the default flags are.

Thanks, it worked just as you said... with these two BindingFlags.

So the code now lookes like:

private void DefineFinalizer (TypeBuilder typeBuilder)
{
MethodBuilder finalizerMethod Builder = typeBuilder.Def ineMethod(
"Finalize",
MethodAttribute s.Family | MethodAttribute s.Virtual |
MethodAttribute s.HideBySig,
CallingConventi ons.Standard,
typeof(void),
Type.EmptyTypes );

ILGenerator generator = finalizerMethod Builder.GetILGe nerator();

generator.Begin ExceptionBlock( );

// Do Finalize stuff here.
generator.EmitW riteLine("Final ize was called");

generator.Begin FinallyBlock();

// Call base.Finalize()
generator.Emit( OpCodes.Ldarg_0 );
generator.Emit( OpCodes.Call, baseType.GetMet hod("Finalize",
BindingFlags.No nPublic | BindingFlags.In stance));

generator.EndEx ceptionBlock();

generator.Emit( OpCodes.Ret);
}
