对于C#日志记录，如何以最小的开销获得调用堆栈的深度? [英] For C# logging, how do I obtain the call stack depth with minimal overhead?

问题描述

我为 Log4net 创建了一个包装器(我可能会赞成这么做) NLog；我还没有决定)，并缩进记录的消息结果以给出调用结构的想法.例如:

I have created a wrapper for Log4net (which I may be dropping in favor of NLog; I haven't decided yet), and I indent the logged messages result to give an idea of calling structure. For example:

2011-04-03 00:20:30,271 [CT] DEBUG  -     Merlinia.ProcessManager.CentralThread.ProcessAdminCommand - ProcStart - User Info Repository
2011-04-03 00:20:30,271 [CT] DEBUG  -      Merlinia.ProcessManager.CentralThread.StartOneProcess - User Info Repository
2011-04-03 00:20:30,411 [CT] DEBUG  -       Merlinia.ProcessManager.CentralThread.SetProcessStatus - Process = User Info Repository, status = ProcStarting

2011-04-03 00:20:30,411 [CT] DEBUG  -          Merlinia.CommonClasses.MhlBasicLayer.SendToAllConnections - 228 - True - False
2011-04-03 00:20:30,411 [CT] DEBUG  -           Merlinia.CommonClasses.MmlNonThreaded.SendObject - 228
2011-04-03 00:20:30,411 [CT] DEBUG  -            Merlinia.CommonClasses.MllTcpSocket.SendMessage - 228 - True
2011-04-03 00:20:32,174 [10] DEBUG  -    Merlinia.CommonClasses.MReflection.CreateFromBinary
2011-04-03 00:20:32,174 [10] DEBUG  -     Merlinia.CommonClasses.MReflection.CopyFromBinary - Bytes = 71

2011-04-03 00:20:32,174 [CT] DEBUG  -  Merlinia.ProcessManager.CentralThread.ProcessProcessInfoAndRequests - User Info Repository

我使用System.Diagnostics.StackTrace并计算StackFrames来执行此操作.

I do this using System.Diagnostics.StackTrace and counting StackFrames.

现在这是一个问题:有没有更有效的方法?我只需要确定(相对)调用堆栈的深度，即当前深度加上或减去上一次调用日志记录包装器的深度即可. (请注意，我实际上并没有使用StackFrame对象，否则我会获得方法名称.)

Now here's the question: Is there any more efficient way of doing this? I only need to determine the (relative) call stack depth, i.e., is the current depth plus or minus what it was the last time my logging wrapper was called. (Note that I do not actually use the StackFrame objects - I get the method names otherwise.)

我希望查询呼叫堆栈深度或堆栈使用情况的简单高性能方法.

I'm hoping for some simple high-performance way of querying the call stack depth or stack usage.

推荐答案

只需使用

Simply use the StackTrace.FrameCount property, and compare it to the previously recorded FrameCount. FYI, FrameCount is probably the fastest method to retrieve the actual frame count, since it only returns the internal m_iNumOfFrames field back to you.
