在上一节，我们学习了 ChineseLunisolarCalendar类的简单用法，但是最终获得的结果不是那么符合国人的习俗。
例如，农历的2017年1月23日往往写做： 二O一七年正月廿三日。这一节将完善上一节的结果。
界面还是上一节一样。
主要代码：
Dim chineseCallDay() As String = {"", "一", "二", "三", "四", "五", "六", "七", "八", "九"}
Dim chineseCallMonth() As String = {"正", "二", "三", "四", "五", "六", "七", "八", "九", "十", "十一", "腊"}
Dim chineseCallYear() As String = {"〇", "一", "二", "三", "四", "五", "六", "七", "八", "九"}
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim chineseCalendar As New ChineseLunisolarCalendar
Dim nowdate As DateTime = New DateTime(2017, 2, 19)
Dim chineseY As Integer = chineseCalendar.GetYear(nowdate)
Dim chineseM As Integer = chineseCalendar.GetMonth(nowdate)
Dim chineseD As Integer = chineseCalendar.GetDayOfMonth(nowdate)
Dim leapMonth As Integer = chineseCalendar.GetLeapMonth(chineseY)
Dim isLeap As Boolean = False
If leapMonth > 0 Then
If leapMonth = chineseM Then
isLeap = True
chineseM -= 1
ElseIf chineseM > leapMonth Then
chineseM -= 1
End If
End If
TextBox1.Text = getChineseYear(chineseY) & "年" & IIf(isLeap, "闰", "") & getChineseMonth(chineseM) & "月" & getChineseDay(chineseD)
End Sub
Private Function getChineseDay(ByVal theDay As Integer) As String
Dim callDay As String
If theDay < 10 Then
callDay = "初" & chineseCallDay(theDay)
Return callDay
End If
If theDay >= 10 And theDay < 20 Then
callDay = "十"
callDay &= chineseCallDay(theDay Mod 10)
Return callDay
End If
If theDay >= 20 And theDay < 30 Then
callDay = "廿"
callDay &= chineseCallDay(theDay Mod 10)
Return callDay
End If
If theDay >= 30 Then
callDay = "三十"
callDay &= chineseCallDay(theDay Mod 10)
Return callDay
End If
End Function
Private Function getChineseMonth(ByVal theMonth As Integer) As String
Return chineseCallMonth(theMonth - 1)
End Function
Private Function getChineseYear(ByVal theYear As Integer) As String
Dim callYear As String = ""
Dim strYear As String = CType(theYear, String)
Dim intMidYear As Integer
For i As Integer = 0 To strYear.Length - 1
intMidYear = Integer.Parse(strYear.Substring(i, 1))
callYear &= chineseCallYear(intMidYear)
Next
Return callYear
End Function
同时结果还说明了是不是闰月，代码比较简单，不在解说。
运行结果，2017年2月19对应的农历：
