Using Reflection.Emit to create a class implementing an interface

Question

I need to generate a class using Reflection.Emit that implements the following interface.

public interface IObject
{
    T Get(string propertyName);         


        

Answer 1

You forgot to BOX the return:

internal delegate object FastConstructorHandler(object[] paramters);

    private static FastConstructorHandler CreateDelegate(Type Tipo)
    {
        DynamicMethod dynamicMethod = new DynamicMethod(string.Empty,
            typeof(object), new Type[] { typeof(object[]) }, Tipo.Module, false);

        ILGenerator ilg = dynamicMethod.GetILGenerator();

        ilg.DeclareLocal(Tipo);
        ilg.Emit(OpCodes.Ldloca_S, (byte)0);
        ilg.Emit(OpCodes.Initobj, Tipo);
        ilg.Emit(OpCodes.Ldloc_0);
        ilg.Emit(OpCodes.Box, Tipo);
        ilg.Emit(OpCodes.Ret);

        return (FastConstructorHandler)dynamicMethod.CreateDelegate(typeof(FastConstructorHandler));
    }
