c#  如何让光标随着文字往后移？？？




  

这个代码应该做你想：

using System;
using System.Windows.Forms;

namespace 文字
{
    public partial class Form1 : Form
    {
        private Timer timer1 = new Timer();
        private TextBox textBox1 = new TextBox()
        {
            Width = 250
        };
        private string s = "苟利国家生死以，" + "\r\n" + "岂因祸福避趋之。";
        private int i = 0;

        public Form1()
        {
            this.Controls.Add(textBox1);

            this.Load += Form1_Load;
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            textBox1.Text += s[i];

            i++;

            if (i >= s.Length) timer1.Stop();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            timer1.Interval = 500;
            timer1.Tick += timer1_Tick;
            timer1.Start();
        }
    }

    class Test
    {
        static void Main()
        {
            Application.Run(new Form1());
        }
    }
}
