Is it possible to use NBuilder to Build a collection of random strings?

Question

pretty simple question: can I use NBuilder to create a collection of x number of random strings?

I was trying...

// NOTE: Tags need to be lowercase.
return Builder<string>
    .CreateListOfSize(10)
    .WhereAll()
        .Has(x => x = randomGenerator.Phrase(15))
    .WhereTheFirst(1)
        .Has(x => x = "time")
    .AndTheNext(1)
        .Has(x => x = "place")
    .AndTheNext(1)
        .Has(x => x = "colour")
    .Build();

but it was run-time erroring, something about I needed to call some specific constructor or something.

Anyone have any ideas?

NBuilder creates objects by using the default (parameterless) constructor. The exception you are receiving is because the String class doesn't have a default constructor.

To create a list of random strings, you could use the Phrase method inside a loop. Maybe not as clean as a single NBuilder chain, but it gets the job done:

   List<string> stringsList = new List<string>();
   var generator = new RandomGenerator();
   for (int i = 0; i < 10; i++)
   {
       stringsList.Add(generator.Phrase(15));
   }

   return stringsList;
