c# - 标签滚动效果

Question

我正在使用一个标签，其中从文本框输入的文本显示在该标签中。现在，我想让标签文本滚动。我通过互联网环顾四周，并尝试将其写入标签内的代码:

private void label1_Click(object sender, EventArgs e)
{
    int Scroll;
    string strString = "This is scrollable text...This is scrollable text...This is scrollable text";

    Scroll = Scroll + 1;
    int iLmt = strString.Length - Scroll;
    if (iLmt < 20)
    {
        Scroll = 0;
    }
    string str = strString.Substring(Scroll, 20);
    label1.Text = str;
}

有人看到我做错了什么吗？

Answer 1

//更简单:

private void timer2scroll_Tick(object sender, EventArgs e)
{
  label10Info.Text = label10Info.Text.Substring(1, label10Info.Text.Length - 1) + label10Info.Text.Substring(0,1);
}
