Function MyGet(Srg As String, Optional n As Integer = False)
‘n为1，取汉字，n为2，取字母，n为0，取数字
Dim i As Integer
Dim s, MyString As String
Dim Bol As Boolean

For i = 1 To Len(Srg)
s = Mid(Srg, i, 1)
If n = 1 Then
Bol = Asc(s) < 0 ‘文字
ElseIf n = 2 Then
Bol = s Like "[a-z,A-Z]" ‘字母
ElseIf n = 0 Then
Bol = s Like "#" ‘数字
End If
If Bol Then MyString = MyString & s
Next

MyGet = IIf(n = 1 Or n = 2, MyString, Val(MyString))

End Function
