用什么在GUI界面中可以输出循环中的多个数值呢？求助~（这程序不知道如何改）
namespace WindowsFibonacci数列
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        int returnValue(int num1)
        {
            int Fibonacci = 1;
            if (num1 == 1 || num1 == 2)
            {
                return 1;
            }
            else
            {
                Fibonacci = returnValue(num1 - 1) + returnValue(num1 - 2);
                return Fibonacci;
            }
        }
        private void btn_Click(object sender, EventArgs e)
        {
            int n,z,j;
            n = int.Parse(tBox.Text);
            z = 1;
            for (j = 1; j <= n; j++)
            {
                z = returnValue(j);
                MessageBox.Show(z.ToString());
            }
           
        }
    }
}

循环中将结果保存到数组，最后返回这个数据再输出 不就可以了吗

        public void ShowInfo(string s)
        {
            rtb.AppendText("\n" + s);
            rtb.Select(rtb.TextLength, 0);
            rtb.ScrollToCaret();
        }

        private void btn_Click(object sender, EventArgs e)
        {
            ShowInfo("-----" + DateTime.Now.ToString("mm:ss") + "-----");
            int n, z, j;
            n = int.Parse(tBox.Text);
            ShowInfo("n=" + n);
            z = 1;
            for (j = 1; j <= n; j++)
            {
                z = returnValue(j);
                ShowInfo("j=" + j + "\tz=" + z);
            }
            ShowInfo("-----Over-----");
        }

单纯显示结果的话你可以用RichTextBox rtb
            rtb.ReadOnly = true;
            rtb.BackColor = SystemColors.Window;

如果还要对结果进行其他操作的话 就该考虑 listbox listview checklistbox datagridview等等了
