多个属性的FluentValidation规则 [英] FluentValidation rule for multiple properties

问题描述

我有一个FluentValidator，它具有zip和county等多个属性.我想创建一个规则，该规则具有两个属性，就像RuleFor构造

I have a FluentValidator that has multiple properties like zip and county etc. I want to create a rule that takes two properties just like a RuleFor construct

public class FooArgs
{
    public string Zip { get; set; }
    public System.Guid CountyId { get; set; }
}

public class FooValidator : AbstractValidator<FooArgs>
{
    RuleFor(m => m.CountyId).Must(ValidZipCounty).WithMessage("wrong Zip County");
}

这可行，但我想将邮编和县名都传递到路e以进行验证.达到此目的的最佳方法是什么?

This works but I want to pass both Zip and county to the rue in order to validate. What is the best method to achieve this?

推荐答案

有Must重载，还为您提供了

There is a Must overload that also provides you with the FooArgs object documented here. It allows you to easily pass both arguments into your method like this:

RuleFor(m => m.CountyId).Must((fooArgs, countyId) =>
    ValidZipCounty(fooArgs.Zip, countyId))
    .WithMessage("wrong Zip County");
