Describing the data structure in C # 1: Code details for the statistical code execution time object

To customize the class calctimingfor the execution time of a statistic code, consider:

• Garbage collection is not allowed during the execution of the statistics. That is, before the statistics code execution time, let the GC complete garbage collection.

• Ensure that the execution time of the code in the current process is counted.

  Write the following code:

    public class calctiming    {        TimeSpan startTime;                Private TimeSpan endTime;        TimeSpan duration;                Public calctiming ()        {            startTime = new TimeSpan (0);            Duration = new TimeSpan (0);        }        public void StartTime ()        {            //enforces garbage collection for all generations            GC. Collect ();            Suspends the thread, and the finalizer thread empties the queue until the            GC. WaitForPendingFinalizers ();            The start time of the user running the code               StartTime = process.getcurrentprocess (). userprocessortime;         }        The statistics of the Code execution time public        void StopTime ()        {            endTime = process.getcurrentprocess (). Userprocessortime;            Duration = Endtime.subtract (startTime);                   }        Returns the time spent by the code execution of a statistic public        TimeSpan Result ()        {            return duration;        }    }

Using the above calctiming class, statistics show the consumption time of the array:

    Class program    {        static void Main (string[] args)        {            int[] nums = new int[100000];            Buildarray (nums);            Calctiming calctime= new Calctiming ();            Calctime.starttime ();            Displaynums (nums);            Calctime.stoptime ();            Console.WriteLine (String. Format ("shared time: {0} ms", Calctime.result (). TotalMilliseconds));            Console.read ();        }        static void Buildarray (int[] arr)        {for            (int i = 0; i < 100000; i++)                arr[i] = 1;        }        static void Displaynums (int[] arr)        {for            (int i = 0; I <= arr. GetUpperBound (0); i++)                    Console.Write (Arr[i] + "");        }    }

Summarize, in the next use C # to describe all data structures, the time spent in statistics, the use of calctiming objects.
