Answer 1

DateTime dt = DateTime.Now;
while (!(dt.DayOfWeek == System.DayOfWeek.Sunday))
{
    dt = dt.AddDays(-1);
}可以改为DateTime dt = DateTime.Now;
dt = dt.AddDays(-(int)dt.DayOfWeek);

Answer 2

或者
DateTime dt = DateTime.Now.AddDays(-(int)DateTime.Now.DayOfWeek);

Answer 3

string dt = DateTime.Now.DayOfWeek.ToString();
        switch (dt)
        {
            case "Monday": dt = "星期一"; break;
            case "Tuesday": dt = "星期二"; break;
            case "Wednesday": dt = "星期三"; break;
            case "Thursday": dt = "星期四"; break;
            case "Friday": dt = "星期五"; break;
            case "Saturday": dt = "星期六"; break;
            case "Sunday": dt = "星期日"; break;
        }
        Label1.Text = dt.ToString() ;
