转储文件在哪里是monitor.wait入口点？以及如何找到等待的原因？

时间：2017-06-04 05:03:34

标签： debugging asp.net-core .net-core windbg dump

在以下转储文件中

  

windbg！dumpstack

monitor.wait入口点在哪里？

以及我如何找到等待的原因？

和导致等待的功能？

我确定等待发生在这里，但我无法通过转储文件找到我的方式

等待发生在哪个功能？

我怎样才能进一步调查等待的原因？

是否有任何资源或教程可以找到这种等待的原因？

在ManualResetEventSlim.Wait中调用Monitor.Wait。

ManualResetEventSlim类在等待设置事件时进行一些旋转，如果事件在轮询/旋转时未设置，则会调用Monitor.Wait。

快速扫描堆栈跟踪，看起来您正在等待异步任务完成。这里是等待开始的地方..只需按照堆栈跟踪（转储堆栈对象来查找并进一步分析传入的粗体任务或！clrstack -a可能会获得更多参数和本地信息）。
