引入包

FluentValidation

一、Student

public class Student
    {
        public int ID { get; set; }

        public string Name { get; set; }

        public string Sex { get; set; }

        public string Phone { get; set; }

        public string Address { get; set; }
    }

二、ExcelAddValidator验证规则cs

构造函数添加规则

   public class ExcelAddValidator:AbstractValidator<Student>
    {
        public ExcelAddValidator()
        {
            RuleFor(o => o.Name).Must(f => f.Length < 2).WithMessage("字符串长度超标");
            RuleFor(o => o.Sex).Must(o => o == "男" || o == "女").WithMessage("性别输入错误");
        }
    }

三、StuartUp

1.单个注入

//注入AddFluentValidation
services.AddControllersWithViews().AddFluentValidation();
 services.AddTransient<IValidator<Student>, ExcelAddValidator>();

2.批量注入

   .AddFluentValidation(
                fv =>
                {
                    fv.RegisterValidatorsFromAssemblyContaining<ExcelAddValidator>();
                });

四、Controller

 public async Task<int> Add([FromBody]Student student)
        {
        }
