Join Function

從字串陣列中的多個子字串中傳回一個字串。

語法


Join (Text As String Array, delimiter)

傳回值類型

字串型

參數:

Text:字串陣列。

delimiter (可選):用於將傳回的字串中的子字串分隔開的一個字串字元。標準的分割元為空格字元。如果分隔字元是一個零長度字串 "",則子字串將緊密相接,相互間無分隔符。

示例:


Dim a(3)
Sub main()
    a(0) = "ABCDE"
    a(1) = 42
    a(2) = "MN"
    a(3) = "X Y Z"
    JStr = Join1()
    Call Show(JStr, Split1(JStr))
    JStr = Join2()
    Call Show(JStr, Split1(JStr))
    JStr = Join3()
    Call Show(JStr, Split1(JStr))
End Sub
 
Function Join1()
    Join1 = Join(a(), "abc")
End Function
 
Function Join2()
    Join2 = Join(a(), ",")
End Function
 
Function Join3()
    Join3 = Join(a())
End Function
 
Function Split1(aStr)
    Split1 = Split(aStr, "D")
End Function
 
Sub Show(JoinStr, TheArray)
    l = LBound(TheArray)
    u = UBound(TheArray)
    total$ = "=============================" + Chr$(13) + JoinStr + Chr$(13) + Chr$(13)
    For i = l To u
        total$ = total$ + TheArray(i) + Str(Len(TheArray(i))) + Chr$(13)
    Next i
    MsgBox total$
End Sub
