需要在逗号之前获得字符

Question

考虑一个字符串是否有多个逗号（，）我想获得excel VBA宏中每个逗号之前存在的3个字符。例如在字符串＆＃34; AR6，AB4，UUF，ABG，UUG，AC4，ABF，＆＃34;在这个字符串中我想首先获得AR6的值然后打印然后第二个AB4，依此类推。该字符串可能包含n个逗号。能帮我解决这个问题。

Answer 1

试试这个：

Sub test()
 Dim st As String
 Dim a As Variant
 st = "AR6, AB4, UUF, ABGtt, UUGyy, AC4, ABF,"
 a = Split(st, ",")
 For i = 0 To UBound(a)
  Debug.Print Left(Trim(a(i)), 3)
 Next
End Sub
