我想从C#应用程序的英特尔芯片中采样硬件事件“指令失效”或“独占指令失效”。
具体来说，我需要在函数调用的开头和结尾对这个数字进行采样，因此根据本文在visualstudio2010中使用cpu计数器运行评测：

没有帮助。使用CPU计数器并运行采样配置文件，您可以获得整个应用程序的失效指令总数。我不能重新组装这个应用程序只调用这个函数，所以我需要更具体地说明这个指令失效示例的“开始”和“结束”。
有人知道某些程序集指令会读取指令失效硬件事件吗？据推测，如果这是可用的，我可以以某种方式直接从C#方法的开头和结尾调用这个汇编指令。
PAPI是一个非常有前景的线索，然而，我相信他们在几年前就停止了对Windows（因此也停止了对.NET C#）的支持。
在窗口方面，Visual Studio 2010 Premium附带了性能资源管理器。如果在检测模式下运行任何项目或二进制文件，则可以访问硬件事件，例如失效的指令。
根据外部因素的不同，结果可能有些混合和不一致，但它与Visual Studio很好地集成在一起，您可以在每个方法/模块级别上获得详细的计数（平均值、最大值、总数）。
Intel V-tune性能分析器也在本机上公开了这些特性。我还没有使用过这个工具，但它可能是一个比VisualStudio2010公开的更灵活的API。
