通過反射計算方法執行時間 包括out參數

        public static long GetMethodRunTime(Type ClassType, object[] ClassParameters, string MethodName, object[] MethodParameters,Type[] MethodParametersType)
        {
            object obj = Activator.CreateInstance(ClassType, ClassParameters);
            MethodInfo method = ClassType.GetMethod(MethodName, MethodParametersType);
            Stopwatch stopWatch = new Stopwatch();
            stopWatch.Start();
            method.Invoke(obj, MethodParameters);
            stopWatch.Stop();
            return stopWatch.ElapsedTicks;///Stopwatch.Frequency/1000;
            
        }

int x = -1;
            long time =  Helper.GetMethodRunTime(typeof(T_RoleService),null,"QueryByPage",new object[]{1,x},new Type[]{ typeof(Int32),typeof(int).MakeByRefType() });
            MessageBox.Show(time.ToString());

注意typeof(int).MakeByRefType()，這裏關聯out
