系统反射向propertyInfo添加代码

我不熟悉这个系统。反射Emit并尝试删除nuget PropertChanged。Fody从我的库中创建了类似的东西。 这个方法叫做UpdateProperty,但实际上是覆盖PropertyInfo,所以如果我的PropertyInfo不是虚拟的,那么这段代码就无法工作。 那么,是否可以只更新我的PropertyInfo集而不创建新属性?

    private static void UpdateProperty(PropertyInfo propertyInfo, TypeBuilder typeBuilder, 
                                       MethodInfo raisePropertyChangedMethod)
    {
        // Update the setter of the class, here is the problem im creating new PropertyInfo
        PropertyBuilder propertyBuilder = typeBuilder.DefineProperty(propertyInfo.Name,
        PropertyAttributes.None, propertyInfo.PropertyType, null);

        // Create set method
        MethodBuilder builder = typeBuilder.DefineMethod("set_" + propertyInfo.Name, MethodAttributes.Public | MethodAttributes.Virtual , null, new Type[] { propertyInfo.PropertyType });
        builder.DefineParameter(1, ParameterAttributes.None, "value");
        ILGenerator generator = builder.GetILGenerator();

        // Add IL code for set method
        generator.Emit(OpCodes.Nop);
        generator.Emit(OpCodes.Ldarg_0);
        generator.Emit(OpCodes.Ldarg_1);
        generator.Emit(OpCodes.Call, propertyInfo.GetSetMethod());

        // Call property changed for object
        generator.Emit(OpCodes.Nop);
        generator.Emit(OpCodes.Ldarg_0);
        generator.Emit(OpCodes.Ldstr, propertyInfo.Name);
        generator.Emit(OpCodes.Callvirt, raisePropertyChangedMethod);
        generator.Emit(OpCodes.Nop);
        generator.Emit(OpCodes.Ret);
        propertyBuilder.SetSetMethod(builder);
    }
