如何在 Windows 中获取内存缓存？

Question

I have searched around a lot but not really found anything. I need the memory cache (on the picture 522 MB). How do I get this value, can someone help me? Screenshot of cache

Can i access this via "Win32_OperatingSystem"?`

Thanks for your help :)

Here is the implementation of @Panagiotis Kanavos solution from comments (Program prints values in GB):

PerformanceCounter counter1 = new PerformanceCounter("Memory", "Cache Bytes");
PerformanceCounter counter2 = new PerformanceCounter("Memory", "Modified Page List Bytes");
PerformanceCounter counter3 = new PerformanceCounter("Memory", "Standby Cache Reserve Bytes");
PerformanceCounter counter4 = new PerformanceCounter("Memory", "Standby Cache Normal Priority Bytes");
PerformanceCounter counter5 = new PerformanceCounter("Memory", "Standby Cache Core Bytes");
while (true)
{
    Console.Clear();
    long bytes = counter1.NextSample().RawValue +
        counter2.NextSample().RawValue +
        counter3.NextSample().RawValue +
        counter4.NextSample().RawValue +
        counter5.NextSample().RawValue;
    Console.WriteLine(bytes / 1024f / 1024f / 1024f);
    Thread.Sleep(1000);
}

The only issue is that when I try to create the counter for Standby Cache Code Bytes , the exception throws, saying that there is no such counter called Standby Cache Code Bytes . So I found a counter named Standby Cache Core Bytes and assumed that it might be just a typo in docs.

The description for Standby Cache Core Bytes is:

Standby Cache Core Bytes is the amount of physical memory, in bytes, that is assigned to the core standby cache page lists. This memory contains cached data and code that is not actively in use by processes, the system and the system cache. It is immediately available for allocation to a process or for system use. If the system runs out of available free and zero memory, memory on lower priority standby cache page lists will be repurposed before memory on higher priority standby cache page lists.
