C# winform 实现逐个显示文字

如题,可以使用timer控件来实现,可以通过设置timer控件属性中的Interval来设置时间间隔(使用VS2019)

using System;
using System.Diagnostics;
using System.Windows.Forms;

namespace Test
{
    public partial class Form3 : Form
    {
        private const string flash = "逐个文字显示Demo";
        private int stopCount = flash.Length + 15;//停止时间
        private int count = 0;
        private bool finish = false;

        public Form3()
        {
            InitializeComponent();
            //启动计时器
            timer1.Start();
            label2.Text = "";
        }

        private void label1_Click(object sender, EventArgs e)
        {
            
        }

		//timer的tick事件
        private void timer_Display_Tick(object sender, EventArgs e)
        {
            if (finish == false)
            {
                label2.Text += flash.Substring(count, 1); //逐个显示文字 
            }
            //累加计数
            count++;
            if (count == flash.Length)
            {
                finish = true;//文字显示完成
            }
            else if (count >= stopCount)
            {
                timer1.Stop();
                this.Close();//关闭窗口
            }
        }

        private void Button1_Click(object sender, EventArgs e)
        {

        }
    }
}
