C# 获取NegotiatedContentResult的状态代码

如何检查来自此

IHttpActionResult

的

NegotiatedContentResult

是否具有

Ok状态代码

例如

if（ValidateRegistrationStep3（accountModel）=Ok（）{code to run}

var result = ValidateRegistrationStep3(accountModel);

如果在

Locals

中检查

result

，它的

值为
System.Web.Http.Results.NegotiatedContentResult
类型为
的
System.Web.Http.IHttpActionResult{System.Web.Http.Results.NegotiatedContentResult}
，状态为
OK
。如何检查
状态代码

[HttpPost]
[Route("register/validate3")]
public IHttpActionResult ValidateRegistrationStep3(
            [FromBody]AccountRegisterModel accountModel) {
    List<string> errors = new List<string>();

    if (!IsDigits(accountModel.CreditCard, 16)) errors.Add("CreditCard needs to be 16 digits.");

    var regExp = @"^(0[1-9]|1[0-2])\/[0-9]{2}$";
    if (!Regex.IsMatch(accountModel.ExpDate, regExp, RegexOptions.IgnoreCase))
                    errors.Add("Expiration Date is not valid format (MM/YY)");

    if (errors.Count == 0) return Content(HttpStatusCode.OK, "Register Model-3 Valid");
    else return Content(HttpStatusCode.BadRequest, errors.ToArray()); }

然后可以从
控制器中调用helper方法，并检查其返回

if (ValidateRegistrationStep1Inner(accountModel).Count == 0 &&
            ValidateRegistrationStep2Inner(accountModel).Count == 0 &&
            ValidateRegistrationStep3Inner(accountModel).Count == 0)

要回答您的问题，您需要执行结果

public async Task<HttpStatusCode> GetResult()
{
    var response = ValidateRegistrationStep3(accountModel);
    var result = await response.ExecuteAsync(new CancellationToken());
    var statusCode = result.StatusCode;

    return statusCode;
}

你在哪里这样调用控制器操作？您将无法获取状态代码，因为操作正在返回
IHttpActionResult
not
NegotiatedContentResult
请参阅我的更新问题。如何检查IHttpActonResult的状态码？异步方法不实用，但将验证码分解为一个帮助器方法，然后调用和检查它可以避免最初的问题。在OP中查看我的解决方案。
public async Task<HttpStatusCode> GetResult()
{
    var response = ValidateRegistrationStep3(accountModel);
    var result = await response.ExecuteAsync(new CancellationToken());
    var statusCode = result.StatusCode;

    return statusCode;
}

public class RegistrationValidation : IRegistrationValidation
{
    public List<string> Validate(AccountRegisterModel model)
    {
        List<string> errors = new List<string>();

        ...

        return errors;
    }
}

public class RegistrationController : ApiController
{
    private readonly IRegistrationValidation validator;

    // with a DI container
    public RegistrationController(IRegistrationValidation validator)
    {
        this.validator = validator;
    }

    // without a DI container
    public RegistrationController()
    {
        this.validator = new RegistrationValidation();
    }

    public IHttpActionResult ValidateRegistrationStep3(AccountRegisterModel accountModel)
    {
        var errors = validator.Validate(accountModel);

        if (error.Count() == 0)
            return Content(HttpStatusCode.OK, "Register Model-3 Valid");
        ...
    }

    public IHttpActionResult FinishRegistration(AccountRegisterModel accountModel)
    {
        var errors = validator.Validate(accountModel);
        if (errors.Count() == 0)
        {
            ...
        }
    }
}
