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

Make dictionary with factory methods:

var factories = new Dictionary>
{
  {"Trials", () => new Trials()},
  {"Coverage", () => new Coverage()},
// and so on
}

...and throw away switch:

foreach (var item in result)
{
  factories[item.Type]().Process(item.URL);
}
