Join

　　用Join可以把字串陣列合并，例：

Private Sub Form_Load()
    Dim A(2) as String
    A(0) = "德" : A(1) = "本" : A(2) = "立"
    Label1.Caption = Join(A)
End Sub

結果：德 本 立

Private Sub Form_Load()
    Dim A(2) as String
    A(0) = "德" : A(1) = "本" : A(2) = "立"
    Label1.Caption = Join(A, "ABC")
End Sub

結果：德ABC本ABC立

Private Sub Form_Load()
    Dim A(2) as String
    A(0) = "德" : A(1) = "本" : A(2) = "立"
    Label1.Caption = Join(A, "") '空字串
End Sub

結果：德本立
