如何使用FluentValidation同时为多个字段创建规则

using FluentValidation;

public class UserModel
{
    public string Name { get; set; }
    public string Email { get; set; }
    public int Age { get; set; }
}

public class UserValidator : AbstractValidator<UserModel>
{
    public UserValidator()
    {
        RuleFor(x => x.Name).NotEmpty().Length(1, 100);
        RuleFor(x => x.Email).NotEmpty().EmailAddress();
        RuleFor(x => x.Age).InclusiveBetween(18, 99);
    }
}

// 在使用时，可以这样验证模型
var user = new UserModel { Name = "", Email = "invalidEmail", Age = 17 };
var validator = new UserValidator();
var result = validator.Validate(user);

if (!result.IsValid)
{
    foreach (var failure in result.Errors)
    {
        Console.WriteLine($"Property: {failure.PropertyName}, Error: {failure.ErrorMessage}");
    }
}
