Windows Phone monitors memory usage

Debug Windows PhoneProgramWe usually need to know how much memory is occupied by the current program and whether there is any memory leakage.

In the previous Windows Phone 7 tips (5), we mentioned that enableframeratecounter is used to monitor the frame rate when the program is running. The usage is as follows:

// Show graphics profiling information while debugging. if (system. diagnostics. debugger. isattached) {// display the current frame rate counters. application. current. host. settings. enableframeratecounter = true;

}

The following is a detailed explanation of the toolbar on the right.

 

There is no memory usage we want to see here. How can we do this. There is such a class in Windows Phone Microsoft. Phone. info. deviceextendedproperties The memory usage is provided. The specific attributes are as follows:

Attribute Value	Return Value	Description
Devicetotalmemory	Long Integer	Total device memory (in bytes)
Applicationcurrentmemoryusage	Long Integer	Current application memory usage (in bytes)
Applicationpeakmemoryusage	Long Integer	Maximum Application Usage (in bytes)

You may need to write the followingCodeTo view the data

 

Of course, there is also a simpler method, that is, to introduce a DLL (DLL download), and then write a few pieces of code to complete the process.

 DNP.Counter. Enablememorycounter =True;

The default refresh interval is 2 seconds. Of course, you can set the refresh interval by yourself.

 DNP.Counter. Settimerinterval (1 );
