Getting char from string at specified index in the visual basic

问题

As stated how to get char from string at specified index in the visual basic? I look through google and these do not work:

s(index) , s.Chars(index),s,Characters(index)

So how to get char at specified index?

回答1:

If s is your string than you could do it this way:

Mid(s, index, 1)

Edit based on comment below question.

It seems that you need a bit different approach which should be easier. Try in this way:

Dim character As String 'Integer if for numbers
's = ActiveDocument.Content.Text - we don't need it
character = Activedocument.Characters(index)

回答2:

Getting one char from string at specified index

Dim pos As Integer
Dim outStr As String
pos = 2 
Dim outStr As String
outStr = Left(Mid("abcdef", pos), 1)

outStr="b"

回答3:

char = split_string_to_char(text)(index)

------

Function split_string_to_char(text) As String()

   Dim chars() As String
   For char_count = 1 To Len(text)
      ReDim Preserve chars(char_count - 1)
      chars(char_count - 1) = Mid(text, char_count, 1)
   Next
   split_string_to_char = chars
End Function
