从 EXcel VBA 中的 Join() 函数中删除定界符
Remove delimiters from Join() Function in EXcel VBA
我是一名新手程序员，我正在通过 VBA 为 excel 构建一个表单，用户将在其中通过 16 个文本框输入员工的时间 sheet 和他们的姓名首字母形式。文本框数据存储到字符串数组中。代码是：
Dim initials(15) As String
initials(0) = TB_Initials_1
initials(1) = TB_Initials_2
initials(2) = TB_Initials_3
...
initials(15) = TB_Initials_15
在使用查找函数并从 excel sheet 中引用一些数据后，我使用
ActiveCell.Offset(0, 2).Value = Join(initials, ".")
输出如下
"js.rs.............." 到另一个 excel sheet 中的活动单元格，（我只输入了 16 个输入框中的 2 个，因此有两个首字母。JS.RS
尾随 ................ 是我要删除的内容。这将在稍后通过 excel sheet 导入到数据库中。
我怎样才能删除字符串末尾的 xtras ".........'s？我已经尝试了 "Trim()" 函数，但这在我的情况下不起作用。一切我在网上试过似乎也不起作用，或者引用的是工作簿中的项目，而不是文本框。
感谢任何帮助。

谢谢，
您可以像这样构建它而不是使用 Join():
ActiveCell.Offset(0, 2).Value = initials(0)
For Counter = 1 To 15
If initials(Counter) <> "" Then
ActiveCell.Offset(0, 2).Value = ActiveCell.Offset(0, 2).Value + "." + initials(Counter)
End If
Next Counter
这是我刚刚创建的一个函数，用于 trim 数组末尾的空元素：
Function TrimArray(ByRef StringArray() As String) As String()
'This function removes trailing empty elements from arrays
'Searching from the last element backwards until a non-blank is found
Dim i As Long
For i = UBound(StringArray) To LBound(StringArray) Step -1
If StringArray(i) <> "" Then Exit For
Next i
If i < LBound(StringArray) Then i = LBound(StringArray)
'Creating an array with the correct size to hold the non-blank elements
Dim OutArr() As String
OutArr = StringArray
ReDim Preserve OutArr(LBound(StringArray) To i)
TrimArray = OutArr
End Function
您可以这样使用它：
Dim Output() As String
Output = TrimArray(initials)
MsgBox Join(Output, ".") & "."
在Excel2019+中可以在一个字符串中使用WorksheetFunction.TextJoin()：
ActiveCell.Offset(0, 2).Value = WorksheetFunction.TextJoin(".", True, initials)
比较的小例子：
Sub test1()
Dim arr(1 To 15)
For i = 1 To 15
arr(i) = IIf(Rnd() > 0.7, "TXT", "")
Next
Debug.Print "With Join(): " & Join(arr, ".")
Debug.Print "With TextJoin(): " & WorksheetFunction.TextJoin(".", True, arr)
End Sub
输出
With Join(): ..TXT........TXT..TXT..
With TextJoin(): TXT.TXT.TXT
