你好，我想在数据库中存储特定数据的计数，这是一个custome中间件存储日志在数据库中，控制器中的每一个动作返回一个responseResultObkect其中有一些属性的当然结果，它应该得到该对象的结果属性，并给出结果的计数，我不知道我可以解释好或不，但我分享的代码，我希望你能帮助我，谢谢很多。
public ChallengeMiddleware(RequestDelegate RequestDelegate)
{
if (RequestDelegate == null)
{
throw new ArgumentNullException(nameof(RequestDelegate)
, nameof(RequestDelegate) + " is required");
}
_request = RequestDelegate;
}
public async Task InvokeAsync(HttpContext Context, ILogService logService,
IHttpContextAccessor httpContextAccessor, IExceptionService2 exceptionService)
{
Stream originalBody = Context.Response.Body;
ServiceLog logMetadata = await LogRequest(Context);
try
{
if (Context == null)
{
throw new ArgumentNullException(nameof(Context)
, nameof(Context) + " is required");
}
//****************************** Response *************************************
using (var memStream = new MemoryStream())
{
string errorMsg = "";
//Stream originalBody = Context.Response.Body;
Context.Response.Body = memStream;
await _request(Context);
var controllerName = Context.GetRouteData().Values["controller"];
var actionName = Context.GetRouteData().Values["action"];
if (controllerName != null)
{
logMetadata.ControllerName = controllerName.ToString();
}
if (actionName != null)
{
logMetadata.ActionName = actionName.ToString();
}
memStream.Position = 0;
string responseBody = new StreamReader(memStream).ReadToEnd();
memStream.Position = 0;
await memStream.CopyToAsync(originalBody);
if (Context.Response.StatusCode != (int)HttpStatusCode.OK)
{
switch (Context.Response.StatusCode)
{
case (int)HttpStatusCode.Unauthorized:
errorMsg = "دسترسی شما مجاز نمیباشد";
break;
case (int)HttpStatusCode.BadRequest:

break;
case (int)HttpStatusCode.InternalServerError:
errorMsg = "درخواست شما با خطا مواجهه شده است";
break;
}
Context.Response.Body = originalBody;
}
var routeData = httpContextAccessor.HttpContext.GetRouteData();
var apiKey = routeData.Values["ApiKey"];
if (apiKey != null)
{
var apiKeyString = apiKey.ToString();
logMetadata.requestContent = apiKeyString;
}
if (!String.IsNullOrEmpty(responseBody))
try
{
dynamic objectResult = JsonConvert.DeserializeObject(responseBody);
var count = 0;
foreach (var item in objectResult)
{
var result = item.First.result;
if(result!= null)
count++;
}
var count2 = count;
}
catch (System.Exception e)
{
logMetadata.responseOtherContent = responseBody;
}
}
logMetadata.responseContentType = Context.Response.ContentType;
logMetadata.responseDate = DateTime.SpecifyKind(DateTime.Now, DateTimeKind.Utc);
logMetadata.responseStatusCode = (HttpStatusCode)Context.Response.StatusCode;
logService.addAddServiceLog(logMetadata);
//****************************** End Response *************************************
}
catch (Exception e)
{
Context.Response.StatusCode = (int)HttpStatusCode.InternalServerError;
Context.Response.Body = originalBody;
logMetadata.responseResultObject = WriteErrorObjectResultResponse(Context, e.Message);
logMetadata.responseContentType = Context.Response.ContentType;
logMetadata.responseDate = DateTime.SpecifyKind(DateTime.Now, DateTimeKind.Utc);
logMetadata.responseStatusCode = HttpStatusCode.InternalServerError;
logService.addAddServiceLog(logMetadata);
}
}例如，这是我的登录控制器：
[HttpPost("Login")]
public async Task<IActionResult> Login(DTOUserForLogin userForLoginDTO)
{
// Check if username exists and if the username exists check if the username/ password combination is valid
var userFromRepo = await _Service.Login(userForLoginDTO.UserName.ToLower(), userForLoginDTO.Password);
// if username does not exist or username/password combination invalid break out of login process & return error
if (userFromRepo == null)
return await UserNotExist();
else
if (!userFromRepo.Active)
return await UserNotActive();
DTOUserDetails usersToReturn = new DTOUserDetails()
{
Created = userFromRepo.Created,
Id = userFromRepo.ID,
LastActive = userFromRepo.LastActive,
Owner = userFromRepo.Owner,
UserName = userFromRepo.UserName
};
// Fill Lazy Load Current User With All Childs Entity
// CurrentUser = await _userService.GetByID(userFromRepo.ID, DefaultIncludes.UserDefaultIncludes);
string token = new TokenService(_Config).CreateToken(userFromRepo);
DTOUserWithToken dTOUserWithToken = new DTOUserWithToken();
dTOUserWithToken.Token = token;
dTOUserWithToken.User = usersToReturn;
// send token
resultObject = new DTOResultObject(dTOUserWithToken);
//return new OkObjectResult(new List<long> { 1, 2 });
return new OkObjectResult(resultObject);
}这是我的objectresult类：
public class DTOResultObject
{
public DTOResultObject()
{
}
public DTOResultObject(string singleMessage)
{
if (!string.IsNullOrEmpty(singleMessage))
{
serverErrors = new List<DTOError>();
//serverErrors.Add(new DTOError() { Message = singleMessage });
}
}
public DTOResultObject(object _Result)
{
Result = JsonConvert.SerializeObject(_Result);
}
public int Id { get; set; }
public int logId { get; set; }
[JsonIgnore]
public ServiceLog log { get; set; }
[JsonIgnore]
public List<DTOError> serverErrors { get; set; }
public string Result { get; set; }
}例如，我的登录控制器如果登录成功，返回一个DtoObjectResult，它的result属性中有一个json web token，所以我们有一个result属性，我想将数据库中的数字1保存为日志表中的result count，这段challengeMiddleWare代码：
responseBody = responseBody.Replace(@"\", " ");
dynamic objectResult = JsonConvert.DeserializeObject(responseBody);
var count = 0;
foreach (var item in objectResult)
{
var result = item.First.result;
if(result!= null)
count++;
}
var count2 = count;当我跟踪代码时，例如当我调用：“Register“操作，该操作将返回已注册用户的数据、以下值：objectResult变量为：
{{
"id": 0,
"logId": 0,
"log": null,
"serverErrors": null,
"result": "[{\"Id\":27,\"Owner\":\"admin9\",\"UserName\":\"admin9\",\"Created\":\"2023-06-07T17:11:17.2434468+03:30\",\"LastActive\":\"0001-01-01T00:00:00\"}]"
}}我想要count变量的数字1，因为我们只有一个结果为“result”部分，但不幸的是，它给了我数字5，意味着DTOResultObject类中的属性的计数，如id，logId，log，serverErrors和result属性，但我想要result属性中的结果的数字，你能帮我做什么吗？谢谢。

你可能想知道
result属性中有多少组json数据，你可以单独处理result：测试结果：
