            int[] a = {1, 4, 5, 7, 3, 8, 9};
            int inp = 3;

            var m = a.ToList().IndexOf(inp) > a.ToList().IndexOf(7) ? "后" : "前";
            Console.WriteLine("{0} 在 7 之{1}", inp, m);

可以看下我的那个程序该怎么改嘛

private void button1_Click(object sender, EventArgs e)
        {
            var maxTime = list.Select(w => w.WorkTime).Max();

            list.ForEach(w =>
            {
                w.Efficiency = (decimal)(w.WorkTime / maxTime) * 100;
                //if (w.Efficiency <= 100)
                {
                    w.Jam = (decimal)100 - w.Efficiency;
                    w.Wait = 0;
                }
                else
                {
                    w.Jam = 0;
                    w.Wait = (decimal)100 - w.Efficiency;
                }
            });

            this.dataGridView1.DataSource = new List<Work>();
            this.dataGridView1.DataSource = list;
        }

        private void button2_Click(object sender, EventArgs e)
        {
            chart1.Series.Clear();
            Series series1 = new Series("有效");
            Series series2 = new Series("拥堵");
            Series series3 = new Series("等待");
            series1.ChartType = SeriesChartType.StackedColumn;
            series2.ChartType = SeriesChartType.StackedColumn;
            series3.ChartType = SeriesChartType.StackedColumn;
            foreach (var x in list)
            {
                series1.Points.AddY(x.Efficiency);
                series2.Points.AddY(x.Jam);
                series3.Points.AddY(x.Wait);
            }
            chart1.ChartAreas[0].AxisY.Maximum = 100;
            chart1.Series.Add(series1);
            chart1.Series.Add(series2);
            chart1.Series.Add(series3); 
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            list.AddRange(new Work[] { 
                new Work() { WorkStation = 1, WorkTime = 12 },
                new Work() { WorkStation = 2, WorkTime = 15 },
                new Work() { WorkStation = 3, WorkTime = 17 },
                new Work() { WorkStation = 4, WorkTime = 13 },
                new Work() { WorkStation = 5, WorkTime = 11 },
            });

            this.dataGridView1.DataSource = list;
        }
    }
    public class Work
    {
        public int WorkStation { get; set; }
        public double WorkTime { get; set; }
        public decimal Efficiency { get; set; }
        public decimal Jam { get; set; }
        public decimal Wait { get; set; }
    }

打注释的地方我该怎么改呢....才能实现找出最大的然后完成下面的运算。

            int[] a = {1, 4, 5, 7, 3, 8, 9};
            int inp = 3;

            var m = a.ToList().IndexOf(inp) > a.ToList().IndexOf(7) ? "后" : "前";
            Console.WriteLine("{0} 在 7 之{1}", inp, m);
