C# 为什么这不写“为什么？”；“周末”；或；甚至周末在文本框里？

我甚至试着在文本框中写周末或周末，但什么也没出现

DateTime thisDate1 = DateTime.Now;
int day = thisDate1.DayOfYear;
int week = day / 7;
bool even = true;
if ((week % 2) == 0) even = true;
if ((week % 2) == 1) even = false;

if (even == true)
{
    if ((int)thisDate1.DayOfWeek == 6) textBox1.Text = "Even Weekend";
    if ((int)thisDate1.DayOfWeek == 7) textBox1.Text = "Even Weekend";
}
if (even == false)
{
    if ((int)thisDate1.DayOfWeek == 6) textBox1.Text = "Weekend";
    if ((int)thisDate1.DayOfWeek == 7) textBox1.Text = "Weekend";
}

非常感谢您的每一个答案。

我想您今天是在周日测试它。但是

DayOfWeek.Sunday

是

0

，而不是

7

答案是不转换为int：

//if ((int)thisDate1.DayOfWeek == 6) textBox1.Text = "Even Weekend";
//if ((int)thisDate1.DayOfWeek == 7) textBox1.Text = "Even Weekend";
  if (thisDate1.DayOfWeek == DayofWeek.Saturday)  textBox1.Text = "Even Weekend";
  if (thisDate1.DayOfWeek == DayofWeek.Sunday)    textBox1.Text = "Even Weekend";

当INT提供DayOfWeek枚举类型时，为什么要使用INT检查日期

为什么要使用数字？

int week=day/7-周编号不是那么简单…在冰岛，星期五只是周末。摆脱强制转换。作为上述代码的一般提示，使用“else”将大大改进它！我想这个星期一点不是6点或7点。。。您是否尝试查看thisDate1.DayOfWeek返回的内容？为什么不使用注释？（对于无法回答问题的一般提示）
if (even == true)
            {
                if (thisDate1.DayOfWeek == DayOfWeek.Sunday) textBox1.Text = "Even Weekend";
                if (thisDate1.DayOfWeek == DayOfWeek.Saturday) textBox1.Text = "Even Weekend";


        }
    if (even == false)
    {
        if (thisDate1.DayOfWeek == DayOfWeek.Sunday) textBox1.Text = "Weekend";
        if (thisDate1.DayOfWeek == DayOfWeek.Saturday) textBox1.Text = "Weekend";

    }
