ASP.NET 复杂属性中的 FluentValidation

Question

我有以下情况。我有一个class，例如

public class Person 
{
   public SchoolYear FirstYear {get; set;}
   public SchoolYear SecondYear {get; set;}
}

public class SchoolYear
{
   public string YearStartDate {get; set;}
   public string YearEndDate {get; set;}
}

我想确保第二学年的开始是在第一学年结束后的一天，我想用 FluentValidation 库来完成。我该怎么做？

请您检查一下。

   public class PersonValidator : AbstractValidator<Person>
    {
        public PersonValidator()
        {
            RuleFor(x => x.SecondYear).Must((p, s)=> {
                var firstYear = p.FirstYear;
                var secondYear = p.SecondYear;
                return Convert.ToDateTime(secondYear.YearStartDate) == Convert.ToDateTime(firstYear.YearEndDate).AddDays(1);
            })
              .WithMessage("second school year should be ONE DAY AFTER firstYear YearEndDate ");
        }
    }
