Environment: LLBLGenPro Demo (latest version) .Net 2.0 SelfServicing Model

I need to generate a new LLBLGenPro Entity. The only information I have is the GetType() info from an existing entity of the same type. Is there a way to do this?

for example:

newEntity = EntityFactory(existingEntity.GetType())

The newEntity needs to get its starting values from OnInitialization().

This functionality is need to write a custom BindingNavigator component.

Thanks

Use the CreateInstance method of the .NET Activator class.

I haven't tried this but have you looked at the EntityFactoryConverter class? It looks like you can convert the factory type to a concrete factory.

Probably Fran would know how to do this.

If that doesn't work, you could edit your Entity template and add a GetFactory method that returns the factory for the entity. To tell you the truth I am surprised this doesn't already exist.

In the generated code, under the Factory Classes, there is a class GeneralEntityFactory where you can use its create method to create your entity based on the type.

public static IEntity2 Create(EntityType entityTypeToCreate)
{
    IEntityFactory2 factoryToUse = null;
    switch(entityTypeToCreate)
    {
        case POT.EntityType.ActivityEntity:
            factoryToUse = new ActivityEntityFactory();
            break;
        case POT.EntityType.ClientEntity:
            factoryToUse = new ClientEntityFactory();
            break;
    }
    return factoryToUse.Create();
}       

Although I find it useless, but you can modify the templates to generate another similar method that only returns the factoryToUse without creating the entity.

If a Type instance is known (GetType() result), the Activator class of .NET is the best and easiest way to create a new instance.
