有没有办法让标题栏 C# 有打字机效果

Question

就像我希望标题栏具有这种类型的打字机效果，其中每个字母在两秒延迟后出现。

H e l l o P r o g r a m

有两秒的延迟

  private void timer2_Tick(object sender, EventArgs e)
        {
            this.Text = "H";
            timer2.Stop();
            this.Text = "He";

        }

我试过这个..

你在正确的轨道上

using System.Windows.Threading; //add reference to WindowsBase.  this gives you access to the DispatcherTimer
DispatcherTimer timer { get; set; } //i used this because it runs on the UI thread which allows it to update.
int letterCount { get; set; }  //i used this to keep track of how many loops ran
string message { get; set; } // set the message you want to display

public Form1()
{            
    InitializeComponent();
    this.Text = ""; //clear the text.  this can be done in the designer
    letterCount = 0; // set the count to 0
    timer = new DispatcherTimer(); //configure the timer
    timer.Interval = TimeSpan.FromSeconds(1);
    timer.Tick += timer_Tick;
    message = "Hello World!"; //set the message
    timer.Start(); //start the timer
}

void timer_Tick(object sender, EventArgs e)
{
    this.Text += message[letterCount]; // add the letter to the title bar
    letterCount++; // increment the count
    if (letterCount > message.Length -1) // stop the timer once the message finishes to avoid getting an error
    {
        timer.Stop(); // use this to stop after once

        // use this to clear and restart
        letterCount = 0;
        this.Text = "";
    }
}
