log4net 没有将精确时间记录到数据库

Question

我通过 log4net 设置了数据库日志记录。我得到相同的时间戳并且没有异常对象。

追加器：

</appender>

生成此日志：

问题：

按日期排序会破坏实际顺序。模式是 log4net.Layout.RawTimeStampLayout & 数据库列是 Datetime2
当出现异常时，异常本身没有被记录

爆破码：

try
{
    InfoScope($"{LayerName} -> {callerInfo.MethodName} -> Passes bill created. Notifying Security-System...", userId, operationId);
    var notificationResult = await _securitySystem.FocusBillPaymentNotification(billInfoBdo.BillDetails, userId, operationId);

    if (notificationResult.Result)
    {
        InfoScope($"{LayerName} -> {callerInfo.MethodName} -> Notifying Security-System succeeded: Security-System Receipt #{notificationResult.SecuritySystemReceiptNumber}, Message: {notificationResult.Message}", userId, operationId);
    }
    else
    {
        WarnScope($"{LayerName} -> {callerInfo.MethodName} -> Notifying Security-System failed: {notificationResult.Message}", userId, operationId);
    }
}
catch (Exception exp)
{
    ErrorScope($"{LayerName} -> {callerInfo.MethodName} -> Exception at Security-System Payment notification [{exp.Message}]", exp, userId, operationId);
}

如何使时间戳更加精确？

为什么异常 pobject 不会得到 .ToString()/logged？

这是我使用的 Logging Core：

    #region Error

    [DebuggerStepThrough]
    protected void ErrorScope(string message, string userId, Guid operationId)
    {
        SetUserId(userId);
        SetOperationId(operationId);
        Logger.ErrorFormat(message);
    }

    [DebuggerStepThrough]
    protected void ErrorScope(string message, Exception exception, Guid operationId)
    {
        SetOperationId(operationId);
        Logger.ErrorFormat(message, exception.GetInnerExceptions());
    }

    [DebuggerStepThrough]
    protected void ErrorScope(string message, Exception exception, string userId, Guid operationId)
    {
        SetUserId(userId);
        ErrorScope(message, exception, operationId);
    }

    #endregion

Answer 1

好吧，这不是问题的直接解决方案，但我确实设法以不同的方式获得了正确的时间戳：我向数据库添加了另一列，类型为 DateTime2，默认为 SysDateTime():

RecordStamp DATETIME2 NOT NULL CONSTRAINT DF_MainLog_RecordStamp DEFAULT (SYSDATETIME())

现在，该专栏负责确保每个日志条目都具有有效的时间戳。
