using System.Linq;
using System.Text;
using System.Threading.Tasks;

using System.Diagnostics;//Stopwatch
namespace CS_VPOS
{
    public class ConsumeTime

            m_stopWatch.Stop();

            // Get the elapsed time as a TimeSpan value.
            TimeSpan ts = m_stopWatch.Elapsed;
            // Format and display the TimeSpan value.
            string elapsedTime = String.Format("{0:00}:{1:00}:{2:00}.{3:00}",ts.Hours, ts.Minutes, ts.Seconds,ts.Milliseconds / 10);
            
            m_StrEndFileLine = String.Format("File : {0} , Line : {1}", CallStack.GetFileName(), CallStack.GetFileLineNumber());

            MessageBox.Show(m_StrStartFileLine + " ~ " + m_StrEndFileLine + " consume time: " + elapsedTime, m_StrTitle);
        }

    }
}

功能:計算相關演算法的所需執行時間，[UI反應時間一般規定3秒，SQL 查詢時間一般只占全部1/6=0.5秒]
