如何将一个月的第一天作为一周工作日？ [英] How to get a first day of a month as a week day?

问题描述

我希望将一个月的第一天作为工作日，例如在2013年1月1日输出应该是星期四。

I want to get a first day of a month as week day, e.g. on 01/January/2013 output should be Thursday.

推荐答案

DateTime类内置了：

The DateTime class has that built in:

DateTime dt = DateTime.ParseExact("01/January/2013", "dd/MMMM/yyyy", CultureInfo.InvariantCulture);
Console.WriteLine(dt.DayOfWeek);

将打印星期二，因为今年1月1日是星期二（不是星期四，因为你的问题说明）

Will Print "Tuesday" since the 1st Jan this year was a Tuesday (not a Thursday as your question states)

// This example demonstrates the DateTime.DayOfWeek property
using System;

class Sample 
{
    public static void Main() 
    {
// Assume the current culture is en-US.
// Create a DateTime for the first of May, 2003.
    DateTime dt = new DateTime(2003, 5, 1);
    Console.WriteLine("Is Thursday the day of the week for {0:d}?: {1}", 
                       dt, dt.DayOfWeek == DayOfWeek.Thursday);
    Console.WriteLine("The day of the week for {0:d} is {1}.", dt, dt.DayOfWeek);
    }
}
/*
This example produces the following results:

Is Thursday the day of the week for 5/1/2003?: True
The day of the week for 5/1/2003 is Thursday.
