Is there a way to retrieve a C# app's current memory usage?
提问by Jeremy
I am automating some profiling tasks and want to log heap space and generation sizes real-time. The profiling APIseems awfully complicated for what I need, and it seems to listen in on individual allocations and collections, which isn't that important to me. Profiling tools are a great help of course, but I was looking for a more flexible, programmable interface.
我正在自动化一些分析任务，并希望实时记录堆空间和生成大小。该分析API看起来太过复杂，我需要什么，它似乎偷听个人分配和收藏，这是不是对我很重要。分析工具当然有很大帮助，但我一直在寻找更灵活、可编程的界面。

The term 'current memory usage' is a little loosely defined. Do you mean the working set? Whatever it means, you can use different properties such as VirtualMemorySize, WorkingSet, PrivateMemorySize, etc. from the process class to retrieve it.
术语“当前内存使用情况”的定义有点松散。你是说工作集吗？不管这意味着，你可以使用不同的属性，如VirtualMemorySize，WorkingSet，PrivateMemorySize，等从工艺类进行检索。
long workingSet = System.Diagnostics.Process.GetCurrentProcess().WorkingSet64;

There are performance counters for a lot of this stuff and if you can't use Perfmon, you can access counters through the Diagnostics API.
有很多这些东西的性能计数器，如果你不能使用 Perfmon，你可以通过诊断 API 访问计数器。

Once I had to find a memory leak in a legacy code, I came accross this solution: Start "tasklist" with appropriate parameters as a process and read the output either from stream or from file.
一旦我不得不在遗留代码中找到内存泄漏，我就遇到了这个解决方案：使用适当的参数启动“任务列表”作为一个进程，并从流或文件中读取输出。
e.g.
例如
tasklist /fi "IMAGENAME eq notepad++.exe" /FO CSV /NH
Output is:
输出是：
"notepad++.exe","7132","Console","1","21.004 K"
Not that elegant, but works in any programming language on Windows without additional dependences (C++/Qt in my case).
不是那么优雅，但可以在 Windows 上的任何编程语言中使用而无需额外的依赖（在我的情况下为 C++/Qt）。
