用vb编写万年历小程序

用VB做万年历，非常关键点就是农历写法，参考代码如下：

#Region " 返回农历 "

'返回农历

'cCalendar.MaxSupportedDateTime 返回支持的最大日期，即2101-1-28

'cCalendar.MinSupportedDateTime 返回支持的最小日期，即190－2-19

Private cCalendar As New System.Globalization.ChineseLunisolarCalendar

Public Function PubFunGet_CNDate(ByVal sDateTime As Date) As String

cCalendar = New System.Globalization.ChineseLunisolarCalendar

Dim lyear As Integer = cCalendar.GetYear(sDateTime)

Dim lmonth As Integer = cCalendar.GetMonth(sDateTime)

Dim lday As Integer = cCalendar.GetDayOfMonth(sDateTime)

Dim lweek As Integer = cCalendar.GetDayOfWeek(sDateTime)

'获取闰月， 0 则表示没有闰月

Dim leapMonth As Integer = cCalendar.GetLeapMonth(lyear)

Dim isleap As Boolean = False

If (leapMonth >0) Then

If (leapMonth = lmonth) Then

'闰月

isleap = True

lmonth = lmonth - 1

ElseIf (lmonth >leapMonth) Then

lmonth = lmonth - 1

End If

End If

Return String.Concat(GetLunisolarYear(lyear), IIf(isleap = True, "闰年", "年"), GetLunisolarMonth(lmonth), "月", GetLunisolarDay(lday))

End Function

'十天干

Private tiangan As String() = {"甲", "乙", "丙", "丁", "戊", "己", "庚", "辛", "壬", "癸"}

'十二地支

Private dizhi As String() = {"子", "丑", "寅", "卯", "辰", "巳", "午", "未", "申", "酉", "戌", "亥"}

'十二升哪生肖

Private shengxiao As String() = {"鼠", "牛", "虎", "免", "龙", "蛇", "马", "羊", "枯笑轿猴", "鸡", "狗", "猪"}

'农历月

Private months As String() = {"正", "二", "三", "四", "五", "六", "七", "八", "九", "十", "十一", "十二(腊)"}

'农历日

Private days1 As String() = {"初", "十", "廿", "三"}

Private days As String() = {"一", "二", "三", "四", "五", "六", "七", "八", "九", "十"}

'返回农历年（天干 地支 生肖）

Private Function GetLunisolarYear(ByVal year As Integer) As String

GetLunisolarYear = ""

If (year >3) Then

Dim tgIndex As Integer = (year - 4) Mod 10

Dim dzIndex As Integer = (year - 4) Mod 12

Return tiangan(tgIndex) &dizhi(dzIndex) &"[" &shengxiao(dzIndex) &"]"

End If

'无效的年份!

End Function

'没肆返回生肖

Private Function GetShengXiao(ByVal sDateTime As Date) As String

Return shengxiao(cCalendar.GetTerrestrialBranch(cCalendar.GetSexagenaryYear(sDateTime)) - 1)

End Function

'返回农历月

Private Function GetLunisolarMonth(ByVal month As Integer) As String

GetLunisolarMonth = ""

If (month <13 AndAlso month >0) Then

Return months(month - 1)

End If

'无效的月份!

End Function

'返回农历日

Private Function GetLunisolarDay(ByVal day As Integer) As String

GetLunisolarDay = ""

If (day >0 AndAlso day <32) Then

If (day <>20 AndAlso day <>30) Then

Return String.Concat(days1((day - 1) \ 10), days((day - 1) Mod 10))

Else

Return String.Concat(days((day - 1) \ 10), days1(1))

End If

End If

'无效的日!

End Function

#End Region

这个只要做一个肆改窗体中包含三个文本框，用于输入出身的年月日，然后计算当前年龄，就要判断，如果现在的月份大约出生的月份，或现在的月份等于出生月份并且现在的日大于大码出生日，年龄就等于今年的年份滚雹哪减去出生年份，否则就等于这个值再减去一。
