C# 获取当前是星期几的方法

C#的功能很强大，却没有直接提供面向汉字文化的开发倾向

比如我现在要说的获取当前的星期我提供两种方法：

①，DateTime.Now.DayOfWeek ，查询MSDN可以知道该属性返回的结果是：

//

// 摘要:

// 获取此实例所表示的日期是星期几。

//

// 返回结果:

// 一个 System.DayOfWeek 枚举常数，它指示星期几。该属性值的范围从零（表示星期日）到六（表示星期六）。

public DayOfWeek DayOfWeek

{

get;

}

依据这个我们想见该属性提供了从星期日到星期六的位置，也就是说是枚举，枚举结合数组不就可以提取我们想要的数据了吗！代码如下：

public string Week()

{

string[] weekdays ={ "星期日" ,"星期一" ,"星期二" ,"星期三" ,"星期四" ,"星期五" ,"星期六" };

string week=weekdays[Convert.ToInt32(DateTime.Now.DayOfWeek)];

return week;

}

你只要调用该方法：Week()就可以得到当前星期几的汉字表示 Lable1.Text=Week();

②第二种方法是直接根据星期的数目比较小还可以直接转化，这时候我们可以用switch关键字代码如下：

public string Week(string weekName)

{

string week;

switch(weekName)

{

case "Sunday":

week = "星期日";

break;

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 = "星期五";

break;

return week;

}

}

你只要调用该方法：Week（DateTime.Now.DayOfWeek）就可以返会汉字的星期几,Lable1.Text=Week(DateTime.Now.DayOfWeek);

C#中获取星期几的中文

System.DateTime.Today.ToString("dddd", new System.Globalization.CultureInfo("zh-CN"));

获取当前星期几实现这个功能有多种方法，接下来将列出3种供参考:

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;

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

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;
