如何检查所选日期是星期几? [英] How do i check if the selected date is of which day in the week?

问题描述

我如何使用if，else语句检查Calendar1中选择的日期是星期一，星期二，星期三，星期四，星期五，星期六还是星期日?
我想写这样的东西:

How do i check if the date selected in Calendar1 is a Monday, Tuesday, Wednesday, Thursday, Friday, Saturday or a Sunday using if, else statement?

As I want to write something like that:

if (//The selected date is a Monday)
        {
            Label6.Text = "Monday";
        }

        else if (//The selected date is a Tuesday)
        {
            Label6.Text = "Tuesday";
        }
.
.

推荐答案

实际上，您根本不需要执行if then语句.您可以简单地执行以下格式:

Actually, you wouldn''t need to do the if then statement at all. You can simply do a format:

Label6.Text = Calendar1.SelectedDate.ToString("dddd");

这样可以将一周中的整天都放在控件中.以下是您可以使用的其他日期格式:

That would put the full day of the week in the control. Here are more date formats you could use:

甚至不需要去麻烦

Don''t even need to go to that trouble

var x = DateTime.Now;
if(x.DayOfWeek == DayOfWeek.Tuesday);

我假设Calendar返回一个DataTime值.我不在ASP.NET中工作

这是确切的解决方案:

I am assuming that Calendar returns a DataTime value. I do not work in ASP.NET

This is the exact solution:

Label6.Text = Calendar1.SelectedDate.DayOfWeek.ToString();
