@H_403_0@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。

@H_403_0@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。

@H_403_0@界面还是上一节一样。

@H_403_0@主要代码：

    Dim chineseCallDay() As String = {"","一","二","三","四","五","六","七","八","九"}
    Dim chineseCallMonth() As String = {"正","九","十","十一","腊"}
    Dim chineseCallYear() As String = {"〇","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

@H_403_0@同时结果还说明了是不是闰月，代码比较简单，不在解说。

@H_403_0@运行结果，2017年2月19对应的农历：
