本文介绍了如何在WPF应用中实现时钟功能，并同步显示当前日期及星期几。通过三种不同的方法，详细讲解了获取星期几的实现过程，帮助开发者更好地在界面中展示日期相关信息。

private DispatcherTimer ShowTimer;
        private void Grid_Loaded(object sender, RoutedEventArgs e)
        {
            ShowTimer = new System.Windows.Threading.DispatcherTimer();

            ShowTimer.Tick += new EventHandler(ShowCurTimer);//起个Timer一直获取当前时间

            ShowTimer.Interval = new TimeSpan(0, 0, 0, 1, 0);

            ShowTimer.Start();     
        }
        public void ShowCurTimer(object sender, EventArgs e)
        {
            label_Time.Content = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");
            label_Week.Content = System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.GetDayName(DateTime.Now.DayOfWeek);
        }

获取星期几的三种方法：

第一种：

string[] Day = new string[] { "星期日", "星期一", "星期二", "星期三", "星期四", "星期五", "星期六" }; 
string week = Day[Convert.ToInt32(DateTime.Now.DayOfWeek.ToString("d"))].ToString(); 
lbDay.Text = week;


第二种：


lbDay.Text = System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.GetDayName(DateTime.Now.DayOfWeek);


第三种：

public static string dt; 
public static string week; 
dt = DateTime.Today.DayOfWeek.ToString(); 
switch (dt) 
{ 
case "Monday": 
week = "星期一"; 
break; 
case "Tuesday": 
week = "星期二"; 
break; 
case "Wednesday": 
week = "星期三"; 
break; 
case "Thursday": 
week = "星期四"; 
break; 
case "Friday": 
week = "星期五"; 
break; 
case "Saturday": 
week = "星期六"; 
break; 
case "Sunday": 
week = "星期日"; 
break; 
} 
lbDay.Text = week;
