How to resolve typelib references when using TypeLibConverter.ConvertTypeLibToAssembly
Im currently trying to use the method TypeLibConverter.ConvertTypeLibToAssembly. Im using the c# example found athttp://msdn2.microsoft.com/en-us/library/k9w7de3e.aspx.
The example works for building a single dll, however the typelib i am converting has multiple references within it which need to be resolved. When the ConversionEventHandler ResolveRef(object typelib) method is called when a reference is found im passed the object typelib (which i dont know what to do with). How do iresolve reference and return a correct assembly?
Any help is appreciated.
Code Example
using System;
using System.Reflection;
using System.Reflection.Emit;
using System.Runtime.InteropServices;
publicclass App
{
private enum RegKind
{
RegKind_Default = 0,
RegKind_Register = 1,
RegKind_None = 2
}
[ DllImport( "oleaut32.dll", CharSet = CharSet.Unicode, PreserveSig =false )]
privatestatic externvoid LoadTypeLibEx( String strTypeLibName, RegKind regKind,
[ MarshalAs( UnmanagedType.Interface )] out Object typeLib );
publicstaticvoid Main()
{
Object typeLib;
LoadTypeLibEx( "Somedll.dll", RegKind.RegKind_None, out typeLib );
if( typeLib ==null )
{
Console.WriteLine( "LoadTypeLibEx failed." );
return;
}
TypeLibConverter converter =new TypeLibConverter();
ConversionEventHandler eventHandler =new ConversionEventHandler();
AssemblyBuilder asm = converter.ConvertTypeLibToAssembly( typeLib, "Interop.Somedll.dll", 0, eventHandler,null,null,null,null );
asm.Save( "Interop.Somedll.dll" );
}
}
publicclass ConversionEventHandler : ITypeLibImporterNotifySink
{
publicvoid ReportEvent( ImporterEventKind eventKind,int eventCode,string eventMsg )
{
// handle warning event here...
}
public Assembly ResolveRef( object typeLib )
{
// resolve reference here and return a correct assembly...
//This is where im not sure how to do it
returnnull;
}
}
