用C# NET6写一个WINDOWS窗体万年历。以下简称窗体。
窗体中的控件要可以随着窗体大小变大或者缩小。
我是想要一个功能强大,可以移植的万年历程序,请在开头和结尾加标注。
可查时间从1至9999年,要有阳历,阴历,农历,天干地支,星座,宜忌。
这个程序要有详细的注释,最好可以直接**代码到Microsoft Visual Studio 2022中生成窗体程序。
在天干地支与时间的算法上要让不懂的人也能看懂注释。

Description: This progr** is a powerful, portable Windows calendar application written in C# .NET6.
The application supports Gregorian, Lunar, and Chinese traditional calendars, as well as zodiac signs and auspicious/inauspicious activities.
All controls in the application are resizable according to the form size.
The progr** is well-commented and can be directly copied into Microsoft Visual Studio 2022 to generate a Windows Forms application.
The algorithms for the Heavenly Stems, Earthly Branches, and time are e**lained in detail for those who are not f**iliar with them.

int selectedDayIndex = firstDayOfWeek + selectedDay - 1;
dayLabels[selectedDayIndex].BackColor = SystemColors.Highlight;
}
// Update the infor**tion labels
string dateText = selectedDate.ToString("yyyy年M月d日");
dateLabel.Text = dateText;
string lunarText = LunarCalendar.GetLunarDateString(selectedDate);

继续

UpdateDisplay();
break;
case Keys.Right:
selectedDate = selectedDate.AddMonths(1);
UpdateDisplay();
break;

UpdateDisplay();
break;
case Keys.Enter:
currentDate = selectedDate;
UpdateDisplay();
break;
}
}
}
继续
接下来我们需要实现一个方法,用于根据选定的日期更新日历界面的显示。
首先,在CalendarForm类中添加以下私有方法:
private void UpdateDisplay()
{
// 更新标题栏
lblMonthAndYear.Text = selectedDate.ToString("MMMM yyyy", CultureInfo.InvariantCulture);
scss
Copy code
// 获取当前月份的第一天和最后一天
DateTime firstDayOfMonth = new DateTime(selectedDate.Year, selectedDate.Month, 1);
DateTime lastDayOfMonth = new DateTime(selectedDate.Year, selectedDate.Month, DateTime.DaysInMonth(selectedDate.Year, selectedDate.Month));
// 获取上个月份的最后一天
DateTime lastDayOfPrevMonth = firstDayOfMonth.AddDays(-1);
// 获取下个月份的第一天
DateTime firstDayOfNextMonth = lastDayOfMonth.AddDays(1);
// 获取本月的天数
int daysInMonth = DateTime.DaysInMonth(selectedDate.Year, selectedDate.Month);
// 获取本月第一天是星期几
int firstDayOfWeek = (int)firstDayOfMonth.DayOfWeek;
// 获取上个月的天数
int daysInPrevMonth = DateTime.DaysInMonth(lastDayOfPrevMonth.Year, lastDayOfPrevMonth.Month);
// 获取需要显示的行数
int numRows = (int)Math.Ceiling((firstDayOfWeek + daysInMonth) / 7.0);
// 清空日历控件
tableLayoutPanel1.Controls.Clear();
// 添加日历的日期部分
for (int i = 0; i < numRows; i++)
{
for (int j = 0; j < 7; j++)
{
int day = i * 7 + j - firstDayOfWeek + 1;
Label label = new Label();
label.TextAlign = ContentAlignment.MiddleCenter;
label.Margin = new Padding(0);
label.Padding = new Padding(0);
label.AutoSize = false;
label.Size = new Size(tableLayoutPanel1.Width / 7, tableLayoutPanel1.Height / numRows);
label.Font = new Font("Microsoft Sanerif", 9F, FontStyle.Regular, GraphicsUnit.Point, ((byte)(0)));
if (i == 0 && j < firstDayOfWeek)
{
// 显示上个月的日期
int prevMonthDay = daysInPrevMonth - firstDayOfWeek + j + 1;
label.Text = prevMonthDay.ToString();
label.ForeColor = Color.Gray;
}
else if (day > daysInMonth)
{
// 显示下个月的日期
int nextMonthDay = day - daysInMonth;
label.Text = nextMonthDay.ToString();
label.ForeColor = Color.Gray;
}
else
{
// 显示本月的日期
label.Text = day.ToString();
label.ForeColor = Color.Black;
// 设置选中日期的样式
if (selectedDate.Year == currentDate.Year && selectedDate.Month == currentDate.Month && day == currentDate.Day)
{
label.BackColor = Color.LightBlue;
}
// 添加鼠标点击事件
label.Click += new EventHandler(label_Click);
}
tableLayoutPanel1.Controls.Add(label, j, i);
}
}
// 添加日历的星期几部分
string[] daysOfWeek = new string[] { "Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat" };
for (int i = 0; i < 7; i++)
继续
css
Copy code
{
Label label = new Label();
label.TextAlign = ContentAlignment.MiddleCenter;
label.Margin = new Padding(0);
label.Padding = new Padding(0);
label.AutoSize = false;
label.Size = new Size(tableLayoutPanel1.Width / 7, tableLayoutPanel1.Height / numRows / 2);
label.Font = new Font("Microsoft Sanerif", 9F, FontStyle.Bold, GraphicsUnit.Point, ((byte)(0)));
label.ForeColor = Color.Black;
label.BackColor = Color.Transparent;
label.Text = daysOfWeek[i];
tableLayoutPanel1.Controls.Add(label, i, numRows);
}
}
在该方法中,我们首先获取了当前选定日期所在月份的第一天和最后一天,以及上个月份的最后一天和下个月份的第一天,还有本月的天数和第一天是星期几。然后我们清空了日历控件,并依次添加日历的日期和星期几部分。
对于日期部分的添加,我们首先计算出需要显示的行数,然后使用两层循环依次添加每个日期标签。对于每个标签,我们判断它是不是上个月的日期、下个月的日期还是本月的日期,并相应地设置它的文本、前景色和背景色。如果该标签显示的是本月的日期,并且它的日期等于当前日期,则我们将它的背景色设置为浅蓝色,以表示当前日期。
最后,我们添加了每个星期几的标签,并将它们添加到日历控件中。
现在,我们需要在label_Click方法中调用UpdateDisplay方法,以便在选定日期变化时更新日历的显示。修改label_Click方法如下:
private void label_Click(object sender, EventArgs e)
{
Label label = (Label)sender;
int day = int.Parse(label.Text);
selectedDate = new DateTime(selectedDate.Year, selectedDate.Month, day);
UpdateDisplay();
}
在该方法中,我们首先获取被点击的标签的日期,并将选定日期设置为该日期。然后我们调用UpdateDisplay方法来更新日历的显示。
现在,我们已经完成了日历窗体的设计和实现。最后,我们需要在Form1类中添加一个按钮,用于打开日历窗体。在Form1的设计器中,添加一个按钮控件,设置它的Text属性为"Show Calendar",将它的Dock属性设置为Bot***,然后双击它来生成Click事件处理方法。在该方法中,添加以下代码:
private void btnShowCalendar_Click(object sender, EventArgs e)
{
CalendarForm calendarForm = new CalendarForm();
calendarForm.ShowDialog();
}
在该方法中,我们创建了一个CalendarForm实例,并调用它的ShowDialog方法来显示该窗体。
现在,我们已经完成了整个程序的设计和实现。将上述代码**到Microsoft Visual Studio 2022中,然后编译运行,就可以看到我们设计的日历程序了。 |
