c# - 在 Bogus 库中为 Enum 生成假数据

Question

我想用 Bogus 创建假数据库来测试数据库性能。这是我的书示例:

    public class Book
    {
        public Guid Id { get; set; }

        public string Title { get; set; }

        public double Price { get; set; }

        public string ISBN { get; set; }

        public Genre Genre { get; set; }
    }

    public enum Genre
    {
        Poetry,
        Romance,
        Thriller,
        Travel
    }
}

另外，我对 Book 中的每个属性都有规则。类来生成假数据。

        public static Faker<Book> Book = new Faker<Book>()
            .StrictMode(true)
            .RuleFor(x => x.Id, f => f.Random.Guid())
            .RuleFor(x => x.Title, f => f.Company.CompanyName())
            .RuleFor(x => x.Price, f => f.Random.Double())
            .RuleFor(x => x.ISBN, f => $"ISBN_{f.Random.Guid()}")
            .RuleFor(x => x.Genre, f => ???);

我的问题是 - 如何为枚举生成随机值 Genre提前致谢!

Answer 1

答案可在 the documentation 中找到本身，
试试

.RuleFor(x => x.Genre, f =>f.PickRandom<Genre>());

你的代码看起来像，

public static Faker<Book> Book = new Faker<Book>()
        .StrictMode(true)
        .RuleFor(x => x.Id, f => f.Random.Guid())
        .RuleFor(x => x.Title, f => f.Company.CompanyName())
        .RuleFor(x => x.Price, f => f.Random.Double())
        .RuleFor(x => x.ISBN, f => $"ISBN_{f.Random.Guid()}")
        .RuleFor(x => x.Genre, f => f.PickRandom<Genre>());
