.net6 fluentvalidation由于并没有对该model所有字段赋值，导致验证不通过

Install-Package FluentValidation

using FluentValidation;
using YourNamespace.Models;

public class ProductValidator : AbstractValidator<Product>
{
    public ProductValidator()
    {
        RuleFor(p => p.Name)
            .NotEmpty().WithMessage("Name is required.")
            .MaximumLength(50).WithMessage("Name cannot exceed 50 characters.");

        RuleFor(p => p.Price)
            .NotNull().WithMessage("Price is required.")
            .GreaterThan(0).WithMessage("Price must be greater than 0.");
    }
}

using FluentValidation.Results;
using YourNamespace.Models;

public class ProductController : Controller
{
    public IActionResult Create(Product product)
    {
        var validator = new ProductValidator();
        ValidationResult result = validator.Validate(product);

        if (result.IsValid)
        {
            // 验证通过，执行其他逻辑
            // ...
        }
        else
        {
            // 验证失败，处理错误信息
            foreach (ValidationFailure failure in result.Errors)
            {
                // 打印错误消息或其他处理
                Console.WriteLine($"{failure.PropertyName}: {failure.ErrorMessage}");
            }
        }

        return View();
    }
