# Join 函数

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
