Question

C＃代码

TextTime.Text = DateTime.Now.ToString();

想要每秒刷新此文本框

或显示数字时钟任何想法

Answer 1

您可以使用DispatcherTimer：

var timer = new DispatcherTimer
{
    Interval = TimeSpan.FromSeconds(1.0)
};
timer.Tick += (o, e) =>
{
    TextTime.Text = DateTime.Now.ToString();
};
timer.Start();

Answer 2

简单的方法是为您的应用添加一个计时器，并按照所示进行操作：

表单加载：

private void Form1_Load(object sender, EventArgs e) {
   txtdate.Text = DateTime.Now.ToString(("dddd" + ("," + "MM-dd-yyyy")));
   Timer1.Interval = 1000;
   Timer1.Enabled = true;
}

计时器勾号：

private void Timer1_Tick(object sender, EventArgs e) {
   txtTime.Text = DateTime.Now.ToString("HH:mm:ss");
}

我想每秒刷新TextBox数字时钟（Windows App）
