How to create a base FluentValidation-CodePudding

namespace Test
{

    public class A
    {
        public string Name { get; set; }
    }    
    public class AValidator : AbstractValidator<A>
    {
        public AValidator()
        {
            RuleFor(t => t.Name)
                .NotEmpty()
                .MinimumLength(10)
                .MaximumLength(20);
        }
    }

    public class B
    {
        public string Name { get; set; }
    }    
    public class BValidator : AbstractValidator<B>
    {
        public BValidator()
        {
            RuleFor(t => t.Name)
                .NotEmpty()
                .MinimumLength(10)
                .MaximumLength(20);
        }
    }
}

tried to create a common like this:

namespace Test2
{
    public interface IPerson
    {
        public string Name { get; set; }
    }

    public abstract class CommonABValidators<T> : 
                           AbstractValidator<T> where T : IPerson
    {
        protected CommonABValidators()
        {
            RuleFor(x => x.Name).NotNull();
        }
    }
}

but by calling

public class AValidator : CommonABValidators<A>

It should be convertible to IPerson, but in my case I have diffeent props in A that are not convertible to IPerson

Any Idea how to extract common params into common Validator?

CodePudding user response：

What you've done looks correct. Just make sure that your class A implements the IPerson interface and the validator will start working.

CodePudding user response：

Another option that you can try at least is to Include rules. Here you can find the official documentation: https://docs.fluentvalidation.net/en/latest/including-rules.html

All you need is to call Include(new CommonValidator()); and the common rules will be automatically included without inheriting a common base type.
