Performance Counter instance under CodeTimer. net in asp.net

This article introduces the performance counter instance under CodeTimer. net in asp.net. If you need it, refer to the example.

Because this is winform, I changed it to WEB output. The execution result is as follows:

The complete code is as follows:

The Code is as follows:

Use the following (GetUser and GetUserBySql are two methods ):

The Code is as follows:	Copy code
MYORM. COMMON. CodeTimer. Time ("MYORM", 10000, () =>{ GetUser ();}); MYORM. COMMON. CodeTimer. Time ("SQL", 10000, () =>{ GetUserBySql ();});
