Creating an object from from an ID (or name)

Question

I have an abstract class that a lot of child classes inherit:

  public abstract class CrawlerBase
    {
        public abstract void Process(string url);
            


        

Answer 1

Does this not work?

foreach (var item in result)
{
    CrawlerBase crawler = null;

    switch (item.Type)
    {
        case "Trials":
            crawler = new Trials(); 
            break;
        case "Coverage":
            crawler = new Coverage();
            break;
        default:
            break;
    }

    if(crawler != null)
        crawler.Process(item.URL);
}
