空间分隔符 [英] Space delimiter
问题描述
让我对vb.net感到愤怒的一件事是
花时间试图让程序做点什么然后
发现已经有了建造程序，
完全相同。
所以在我开始这个之前，任何人都可以告诉我是否有
已经成为这样做的例行程序：
我正在使用
string.split划分分隔的文本字符串。分隔符是一个空格，但
其中有相邻的空格我想将它们视为
单个分隔符。有什么聪明的方法呢？
感谢任何想法
yust a thought
strNew = strOld.replace（""，""）
如果要替换3,4，可以将它放入下一个循环中。 ..空格2

您好Simonc
除了Eric我用stringbuilder制作它，
你问了一些新的东西，这是一个真正快得多的新功能
比所有旧字符串替换功能。但我不知道是否有更好的方式。
Dim a As String =这里有很多空气 ;
Dim sb As New System.Text.StringBuilder（a）
Do while sb.ToString.IndexOf（""）> -1''2个空格
sb.Replace（""，""）
循环
Dim b As String = sb.ToString
Dim c（）As String = Split（b）
我希望这有点帮助吗？

另一种方法是使用正则表达式。这个表达式用一个空格替换所有出现2个或更多空格的
。
导入System.Text.RegularExpressions
strNew = Regex.Replace（strOld，" {2，}"，""）

One of the things that drives me mad about vb.net is
spending time trying to make a program do something then
finding that there''s already an inbuild procedure that
does exactly the same thing.
So before I begin on this can anyone tell me if there is
already a routine to do this:
I am dividing up a delimited textstring using
string.split. The delimiter character is a space, but
where there are adjacent spaces I want to treat these as a
single delimiter. What is the smart way to do this?
Grateful for any ideas

strNew = strOld.replace(" "," ")
you could put it in a for next loop if you want to replace 3,4,... spaces 2

Hi Simonc
In addition to Eric did I make it with stringbuilder,
you asked something new and this is a new function who is real much faster
than all old string replace funtions. But I don''t know if there is not a
better way.
Dim a As String = "There is a lot of for air here"
Dim sb As New System.Text.StringBuilder(a)
Do While sb.ToString.IndexOf(" ") > -1 ''2 spaces
sb.Replace(" ", " ")
Loop
Dim b As String = sb.ToString
Dim c() As String = Split(b)
I hope this helps a little bit?

Yet another method is to use regular expressions. This expression replaces
all occurrences of 2 or more spaces with a single space.
Imports System.Text.RegularExpressions
strNew = Regex.Replace(strOld, " {2,}", " ")
