如何在log4net天蓝色的附加程序中添加/修改LoggingEvent类？

Question

我正在使用log4net Azure附加程序，我的目标是删除不必要的属性，并在Azure Blob存储中添加一些要记录（附加）的属性。 无需尝试创建自己的附加程序，我将如何做到这一点？

似乎仅将某些属性保留为null不会使.DoAppend方法记录任何内容。

         AzureAppendBlobAppender  _appender = new AzureAppendBlobAppender()
        {
            ConnectionString = "myConnString",
            ContainerName = "logs",
            DirectoryName = "logs"
        };
        _appender.BufferSize = 1;
        _appender.ActivateOptions();
        var logEvent = MakeEvent();
        _appender.DoAppend(logEvent);

    private static LoggingEvent MakeEvent()
    {
        return new LoggingEvent(
            new LoggingEventData
            {

                Domain = "testDomain",
                Identity = "testIdentity",
                Level = Level.Critical,
                LoggerName = "testLoggerName",
                Message = "testMessage",
                ThreadName = "testThreadName",
                TimeStamp = DateTime.UtcNow,
                UserName = "testUsername",
                LocationInfo = new LocationInfo("className", "methodName", "fileName", "lineNumber")
            }
            );
    }
