Join Function

将字符串数组中的多个子字符串组合成一个字符串。

语法：

Join (Text As String Array, delimiter)

返回值：

字符串

参数：

Text：字符串数组。

delimiter（可选）：用于分隔返回字符串中的子字符串的字符串字符。默认的分隔字符是空格。如果分隔字符是一个零长度字符串 ""，子串将紧密相接，相互间无分隔符。

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
