' 欲計算字串 S 的長度 | |
N = 0 | |
For I = 1 To Len(S) | |
C = Asc(Mid(S, I, 1)) ' 取得第 I 個字元組的字元碼 | |
If C >= 0 And C < 128 Then ' 英文 | |
N = N + 1 | |
Else ' 中文 | |
N = N + 2 | |
End If | |
Next | |
'補充說明:除了以上方法之外,以下是更快速的計算長度方法: | |
LenB(StrConv("中英Mixed", vbFromUnicode)) ' => 9, 符合此需求 | |
'長度計算比對指令 | |
Len("中英Mixed") ' => 7 | |
LenB("中英Mixed") ' => 14 |
