在Windows 2008 R2，资源监视器中的磁盘活动部分，我可以看到/写入文件读取的字节数。我怎样才能做到这一点的一个纲领性的方式，preferably使用C＃（或Win32 API的）？我已经调查WMI和各种性能计数器，但是我想不通，如果有一些东西，适合我的需要。

In Windows 2008R2, in Resource Monitor in the Disk Activity section I can see the number of bytes read from/written into files. How can I do this in a programmatic manner, preferably using C# (or Win32 API)? I have looked into WMI and various performance counters, however I cannot figure out if there is something which suits my needs.

推荐答案

有关的柜台文件I / O都在逻辑磁盘和物理磁盘的对象。您可以在性能监视器来看看，看看有什么计数器可用。

The counters relating to file I/O are on the LogicalDisk and PhysicalDisk objects. Take a look in Perfmon to see what counters are available.

使用的PerformanceCounter 类在C＃或 PDH API 在C / C ++。在我的经验，这些是更有效的比WMI - 尽管这可能不是在你的申请事项

Use the PerformanceCounter class in C# or the PDH API in C/C++. In my experience these are much more efficient than WMI - though this may not matter in your application.
