从异常

Question

我试图从发起异常的类中获取Class和MethodName。请参阅以下代码：

  [MethodImpl(MethodImplOptions.NoInlining)]
    public void Log(object obj, LogTypes logType, int userId = 0, string userName = "", [CallerFilePath] string sourceFilePath = "",[CallerMemberName] string methodName = "")
    {
        var appLog = new ApplicationLog();
        try
        {
            appLog.UserId = userId;
            appLog.UserName = userName;
            appLog.InstanceName = ConfigurationSettingsHelper.InstanceName;
            appLog.ProjectName = HostingEnvironment.IsHosted ? HostingEnvironment.ApplicationHost.GetSiteName() : Assembly.GetCallingAssembly().GetName().Name;
            appLog.LoggedOn = DateTime.UtcNow;
            appLog.FilePath = sourceFilePath;
            if (logType==LogTypes.Exception)
            {
                if (obj is Exception ex)
                {
                    appLog.LogType = 1;
                    appLog.LogDetails = ex.ToString();
                    if (ex.TargetSite.DeclaringType != null)
                        appLog.ClassName = ex.TargetSite.DeclaringType.FullName;
                    appLog.MethodName = ex.TargetSite.Name;
                    appLog.Message = ex.Message;
                }
            }
            else
            {
                appLog.LogType = 2;
                var reflectedType = new StackFrame(1).GetMethod().ReflectedType;
                if (reflectedType != null)
                    appLog.ClassName = reflectedType.FullName;
                appLog.MethodName = methodName;
                appLog.LogDetails = obj is string ? obj.ToString() : "NA-Not a valid logging.";
            }
        }
        catch (Exception ex)
        {
            //In case of unhandled exceptions.Try logging internal exception once.
            //If failed, pass by silently.
            try
            {
                appLog = new ApplicationLog
                {
                    UserId = userId,
                    UserName = userName,
                    FilePath = new StackFrame(1).GetFileName(),
                    Message = ex.Message,
                    InstanceName = ConfigurationSettingsHelper.InstanceName,
                    ProjectName = Assembly.GetCallingAssembly().GetName().Name,
                    LoggedOn = DateTime.UtcNow,
                    LogType = 1,
                    LogDetails = ex.ToString()
                };
                if (ex.TargetSite.DeclaringType != null)
                    appLog.ClassName = ex.TargetSite.DeclaringType.FullName;
                appLog.MethodName = ex.TargetSite.Name;
            }
            finally
            {
                HttpWebMethods.PostAsync(ConfigurationSettingsHelper.LoggerApiBaseAddress,
                    ConfigurationSettingsHelper.SaveLogEndpoint, appLog);
            } // intentionally eating exception}
        }
        finally
        {
            HttpWebMethods.PostAsync(ConfigurationSettingsHelper.LoggerApiBaseAddress,
                ConfigurationSettingsHelper.SaveLogEndpoint, appLog);
        }
    }

但是上面的代码捕获了错误的类和方法名称。请参阅下面的例外情况。

System.FormatException: Input string was not in a correct format.
   at System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal)
   at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info)
   at System.Convert.ToInt32(String value)
   at Common.ConvertAIToPNG.DAMFileOperation(String fsGUIDFolder, Int32 fiUserID, String fsInputFileName, String& fsOutPutFileName) 
   in c:\Main\PDM\App_code\common\ConvertAIToPNG.cs:line 70
   at DAMFilesUploader.UploadFile(HttpContext context) in c:\Main\PDM\Uploader\DAMFilesUploader.ashx:line 82

我正在捕获并记录此异常以及它发生的类名和方法名称。但我在这里

类：System.Number |方法：StringToNumber

然而，预期应该是 类：ConvertAIToPNG方法：DAMFileOperation

我知道，我正在重新发明轮子。我可以使用Log4Net / Elmah。但是，我仍想弄清楚原因/解决方案。 此外，我在网站而不是WebApp / Windows应用程序中使用此代码。。但我已经考虑了所有案例，并试图使其更通用。

先谢谢。

谢谢，我得到了修复。这是一个简单的修复。

替换

<div class="card" *ngFor="let item of galleries;"
                 (mouseenter)=" setBackground(item?.image?.fullpath)"
                 (mouseover)="showCount = true; getImagesCount(item.path);" (mouseleave)="showCount = false">
                <img class="card-img-top" [routerLink]="['/'+item.path]"
                     [src]="item?.image?.fullpath ? path + '0x156/' + item?.image?.fullpath : defaultImage"
                     alt="Card image cap">
                <div class="card-block">
                    <h4 class="card-title imagesCount"></h4>
                    <h4 class="card-title title">{{item.name}}</h4>
                    <img class="closeIcon" src="../../../assets/images/close.png" alt="" (click)="removeGallery(item);">
                    <span class="animated fadeInUp" *ngIf="showCount">{{imagesCount}}</span>
                </div>
            </div>

用这个

 if (ex.TargetSite.DeclaringType != null)
     appLog.ClassName = ex.TargetSite.DeclaringType.FullName;
     appLog.MethodName = ex.TargetSite.Name;
