FluentValidation不适用于不同的库

using FluentValidation;
using FluentValidation.AspNetCore;
using Microsoft.AspNetCore.Mvc;

public class UserViewModel
{
    public string Name { get; set; }
    public int Age { get; set; }
}

public class UserViewModelValidator : AbstractValidator<UserViewModel>
{
    public UserViewModelValidator()
    {
        RuleFor(x => x.Name).NotEmpty().MinimumLength(3);
        RuleFor(x => x.Age).InclusiveBetween(18, 99);
    }
}

[ApiController]
[Route("[controller]")]
public class UserController : ControllerBase
{
    private readonly UserViewModelValidator _validator;

    public UserController(UserViewModelValidator validator)
    {
        _validator = validator;
    }

    [HttpPost]
    public IActionResult Post([FromBody] UserViewModel user)
    {
        var validationResult = _validator.Validate(user);
        if (validationResult.IsValid)
        {
            // 处理有效的用户数据
            return Ok();
        }
        else
        {
            // 返回验证错误信息
            var errors = validationResult.Errors.Select(e => e.ErrorMessage).ToArray();
            return BadRequest(errors);
        }
    }
}
