Question

我正在尝试创建在C＃中接受5个作业的fcfs。我需要帮助用什么公式来计算等待时间和周转时间。另外，我打算在Convert.ToString（）部分显示输出。我应该如何实施这一个？感谢。

private void btnFCFS_Click(object sender, EventArgs e)
    {
        a1 = Convert.ToInt32(txtAT1.Text); a2 = Convert.ToInt32(txtAT2.Text); a3 = Convert.ToInt32(txtAT3.Text); a4 = Convert.ToInt32(txtAT4.Text);
        a5 = Convert.ToInt32(txtAT5.Text); b1 = Convert.ToInt32(txtBT1.Text); b2 = Convert.ToInt32(txtBT2.Text); b3 = Convert.ToInt32(txtBT3.Text);
        b4 = Convert.ToInt32(txtBT4.Text); b5 = Convert.ToInt32(txtBT5.Text);


        int[][] arrayprocess = new int[][] { new int[] { a1, b1 }, new int[] { a2, b2 }, new int[] { a3, b3 }, new int[] { a4, b4 }, new int[] { a5, b5 } };

        Sort<int>(arrayprocess, 0);

        label8.Text = Convert.ToString(arrayprocess[0][0] + " " + arrayprocess[1][0] + " " +arrayprocess[2][0] + " " +arrayprocess[3][0] + " " +arrayprocess[4][0]);
        label9.Text = Convert.ToString(arrayprocess[0][1] + " " + arrayprocess[1][1] + " " + arrayprocess[2][1] + " " + arrayprocess[3][1] + " " + arrayprocess[4][1]);
        int totalburst = arrayprocess[0][1] + arrayprocess[1][1] +  arrayprocess[2][1] +  arrayprocess[3][1] + arrayprocess[4][1];
        label10.Text = Convert.ToString(totalburst);

        //Gantt Chart
        Graphics dc = this.CreateGraphics();
        Pen Bluepen = new Pen(Color.Blue, 3);
        dc.DrawRectangle(Bluepen, 50, 200, arrayprocess[0][1] *10, 20);
        Pen Redpen = new Pen(Color.Red, 3);
        dc.DrawRectangle(Redpen, 50 + arrayprocess[0][1] * 10, 200, arrayprocess[1][1] * 10, 20);
        Pen Yellowpen = new Pen(Color.Yellow, 3);
        dc.DrawRectangle(Yellowpen, 50 + arrayprocess[0][1] *10 + arrayprocess[1][1] * 10, 200, arrayprocess[2][1] * 10, 20);
        Pen Greenpen = new Pen(Color.Green, 3);
        dc.DrawRectangle(Greenpen, 50 + (arrayprocess[0][1] + arrayprocess[1][1] + arrayprocess[2][1]) * 10, 200, arrayprocess[3][1] * 10, 20);
        Pen Violetpen = new Pen(Color.Violet, 3);
        dc.DrawRectangle(Violetpen, 50 + (arrayprocess[0][1] + arrayprocess[1][1] + arrayprocess[2][1] + arrayprocess[3][1]) * 10, 200, arrayprocess[4][1] * 10, 20);

        lblWT1.Text = Convert.ToString();
        lblWT2.Text = Convert.ToString();
        lblWT3.Text = Convert.ToString();
        lblWT4.Text = Convert.ToString();
        lblWT5.Text = Convert.ToString();

        lblTAT1.Text = Convert.ToString();
        lblTAT2.Text = Convert.ToString();
        lblTAT3.Text = Convert.ToString();
        lblTAT4.Text = Convert.ToString();
        lblTAT5.Text = Convert.ToString();

    }

    public void Sort<T>(T[][] data, int col)
    {
        Comparer<T> comparer = Comparer<T>.Default;
        Array.Sort<T[]>(data, (x, y) => comparer.Compare(x[col], y[col]));          
    }
