RDLC中使用自定义函数实现数字转中文大写（金额） 可以使用聚合函数做参数

1.在代码中写函数

[code lang=”vb”]Function DxMnu(ByVal Money As String, Optional ByVal YB As Boolean = True) As String
Dim X, Y As String
Dim I As Integer
Const Zimu = “.sbqwsbqysbqwsbq” ”定义位置代码
Const Letter = “0123456789sbqwy.zjf” ”定义汉字缩写
Const Upcase = “零壹贰叁肆伍陆柒捌玖拾佰仟万亿圆整角分” ‘定义大写汉字
Dim Temp As String
Try
Temp = Convert.ToString(Format(Convert.ToDouble(Money), “0.00”))
Catch ex As Exception
Throw New NotSupportedException(“数据给出错误（非数字格式）！”)
DxMnu = “Error.”
Exit Function
End Try
If Len(Temp) > 12 Then
Throw New NotSupportedException(“数据太大，无法计算（超亿位无法计算）！”)
DxMnu = “Error.”
Exit Function
End If
If InStr(Temp, “.”) > 0 Then Temp = Left(Temp, InStr(Temp, “.”) – 1)
X = Format(Convert.ToDouble(Money), “0.00”) ‘格式化货币
Y = “”
For I = 1 To Len(X) – 3
Y = Y & Mid(X, I, 1) & Mid(Zimu, Len(X) – 2 – I, 1)
Next
If Right(X, 3) = “.00” Then
Y = Y & “z” ”***元整
Else
If Right(X, 1) = “0” Then
Y = Y & Left(Right(X, 2), 1) & “j” & “z” ‘*元*角*整
Else
Y = Y & Left(Right(X, 2), 1) & “j” & Right(X, 1) & “f” ”*元*角*分
End If
End If
Y = Replace(Y, “0q”, “0”) ”避免零千(如：40200肆萬零千零贰佰)
Y = Replace(Y, “0b”, “0”) ”避免零百(如：41000肆萬壹千零佰)
Y = Replace(Y, “0s”, “0”) ”避免零十(如：204贰佰零拾零肆)
Do While Y <> Replace(Y, “00”, “0”)
Y = Replace(Y, “00”, “0”) ”避免双零(如：1004壹仟零零肆)
Loop
Y = Replace(Y, “0y”, “y”) ”避免零億(如：210億 贰佰壹十零億)
If Val(Mid(Right(Temp, 4), 1, 1)) > 0 Then
Y = Replace(Y, “0w”, “w0″) ”避免无零千(如：102000 拾万贰仟)，应该是拾万零贰仟
Else
Y = Replace(Y, “0w”, “w”) ”避免零萬(如：210萬 贰佰壹十零萬)
End If
‘Y = IIf(Len(X) = 5 And Left(Y, 1) = “1”, Right(Y, Len(Y) – 1), Y) ”避免壹十(如：14壹拾肆；10壹拾)
Y = IIf(Len(X) = 4, Replace(Y, “0.”, “”), Replace(Y, “0.”, “.”)) ”避免零元(如：20.00贰拾零圆；0.12零圆壹角贰分)
If Len(Temp) >= 9 Then ‘加
Y = Replace(Y, “yw”, “y”) ‘避免亿万元　如　100000000，壹亿万元　应该是壹亿元
End If ‘加
For I = 1 To 19
Y = Replace(Y, Mid(Letter, I, 1), Mid(Upcase, I, 1)) ”大写汉字
Next
If YB = False Then
Y = Y.Replace(“圆整”, “”)
End If
DxMnu = Y
End Function[/code]

2.在文本框中写代码（注意加上code）。

="无税金额合计（大写）：" & code.DxMnu(Sum(Fields!bb_sum.Value, "ReportDataSet_BillBody"))
