C#窗体中怎么样把获取的系统当前 星期数 转换成汉字！！！

//获取当前日期的星期 本地语言(中文)
MessageBox.Show(System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.GetDayName(DateTime.Now.DayOfWeek));

public static string dt;
public static string week;
protected void Page_Load(object sender, EventArgs e)
{
//获取当前日期是星期几
dt = DateTime.Today.DayOfWeek.ToString();
//根据取得的星期英文单词返回汉字
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;
}
//利用TextBox文本框显示当前日为星期几
this.lblTest1.Text = week;
}

你可以这样写：DateTime.Now.ToString("dddd")
