在 NLog 中缓冲日志消息并手动将其刷新到目标

我正在尝试通过 NLog MailTarget 进行日志记录。它工作得很好，但我想用 BufferedTargetWrapper 包装邮件目标来缓冲日志消息，直到预定义的代码点，我想手动刷新缓冲区并通过单个发送先前缓冲的日志消息邮件（如邮件目标中定义的）。

如果我定义了 FlushTimeout 或 BufferedTargetWrapper 的 BufferSize ，一切仍然按预期正常工作。但如果未设置 FlushTimeout 和 BufferSize，我将无法使其工作。

就像在这个问题上回答的那样强制 BufferingTargetWrapper 为空 i没有类似的东西：

 LogManager.Configuration.AllTargets.Where(t => t != null && t is BufferingTargetWrapper).ToList().
            ForEach(b => ((BufferingTargetWrapper)b).Flush(null));

但是文档和这个答案与我的 NLog 版本（2.0.0.2000）相矛盾。没有不带参数的flush方法，只有异步目标的flush方法。

有没有办法强制 BufferingTargetWrapper 将所有记录的消息刷新到包装的目标（通过邮件发送）？

I am trying to log via the NLog MailTarget.
It works just fine, but i wanted to wrap the mailtarget with the BufferedTargetWrapper to buffer the log messages until a predefined codepoint, where i want to manually flush the buffer and send the previusly buffered log messages by an single mail (like defined in the mail target).

If I define a FlushTimeout or the BufferSize of the BufferedTargetWrapper everything still works just fine as supposed.
But if the FlushTimeout and the BufferSize is not set, i can't get it to work.

Like answered in this question on SO Force BufferingTargetWrapper to empty i have no something like that:

 LogManager.Configuration.AllTargets.Where(t => t != null && t is BufferingTargetWrapper).ToList().
            ForEach(b => ((BufferingTargetWrapper)b).Flush(null));

But the documentation and this answer is contradictory to my NLog Version (2.0.0.2000).
There is no flush method without parameters, only the flush method for asynchronous targets.

Is there a way to force the BufferingTargetWrapper to flush all the logged messages to the wrapped target (to send it by mail)?

根据文档，您的方法不应该起作用，但没关系。只需给flush方法一个空的lambda表达式：

LogManager.Configuration.AllTargets
    .OfType<BufferingTargetWrapper>()
    .ToList()
    .ForEach(b => b.Flush(e =>
        {
            //do nothing here
        }));

According to the documentation your approach should not work, but it is fine. Just give the flush method an empty lambda expression:

LogManager.Configuration.AllTargets
    .OfType<BufferingTargetWrapper>()
    .ToList()
    .ForEach(b => b.Flush(e =>
        {
            //do nothing here
        }));
