Windows CPU Memory Network Performance Statistics Article 3 CPU multi-core CPU core usage C #

Http://blog.csdn.net/morewindows/article/details/8678382

 

In the previous section, CPU memory network performance statistics for Windows system, article 2 CPU overall usage describes how to obtain the overall CPU usage in Windows XP and Windows 7 systems. Currently, most CPUs are multi-core CPUs, therefore, this article describes how to obtain the usage of each core of a multi-core CPU.

It is very convenient to use C # To obtain the usage of each core of a multi-core CPU. In just a few lines, and the program can run normally in Windows XP and Windows 7 systems. The following code is provided first.

// Windows system CPU Memory Network Performance Statistics third article CPU multi-core CPU core usage C # // tested, can be used in WINXP and win7 // http://blog.csdn.net/morewindows/article/details/8678382using system; using system. diagnostics; using system. threading; namespace consoleapplication1 {class program {static void main (string [] ARGs) {console. writeline ("Windows system CPU Memory Network Performance Statistics Article 3 CPU multi-core CPU core usage C #"); console. writeline ("-http://blog.csdn.net/morewindows/article/details/8678382-"); console. writeline ("-- by morewindows (http://blog.csdn.net/MoreWindows) -- \ n"); performancecounter [] counters = new performancecounter [system. environment. processorcount]; for (INT I = 0; I <counters. length; I ++) {counters [I] = new performancecounter ("processor", "% processor time", I. tostring ();} while (true) {for (INT I = 0; I <counters. length; I ++) {float F = counters [I]. nextvalue (); console. write ("CPU-{0 }:{ 1: F }%", I + 1, F);} console. writeline (); thread. sleep (1000 );}}}}

The Code shows that the performancecounter class in system. Diagnostics is used. This class is powerful. You can refer to msdn for a detailed explanation.

 

In WINXP system running results are as follows (this article supporting program: http://download.csdn.net/detail/morewindows/5160822 ):

 

In win7 system running results are as follows (this article supporting program: http://download.csdn.net/detail/morewindows/5160822 ):

 

From this article "Windows system CPU Memory Network Performance Statistics third article CPU multi-core CPU core usage C #" (http://blog.csdn.net/morewindows/article/details/8678382) can be seen that C # is undoubtedly a very convenient language, for C/C ++ programmers, understanding C # is very helpful.

The next Windows system CPU Memory Network Performance Statistics Fourth Article CPU multi-core CPU core usage of C ++ (http://blog.csdn.net/morewindows/article/details/8678396) this section describes how to use C ++ code to reference the DLL written in C # To obtain the CPU usage of multiple cores in C ++.
