在vb.net中添加一个字符串的空间 [英] add space of one character string in vb.net

问题描述

我在vb.net中有一个字符串：

Hi,
I have a string in vb.net as:

Dim MyString As String = ""

在我执行的执行中字符串的结果如下：

In the execution i got the string result in the following manner:

MyString = 1|2|3|4|5|6|7|8|9|1|2|3|4|5|6|7|8|9

所以我希望在字符串9 | 1之间有空格，例如

so what i want to have a space between the string 9|1 like for e.g.

1|2|3|4|5|6|7|8|9 |1|2|3|4|5|6|7|8|9

怎么办？



接下来的问题是在字符串中假设9后我必须创建单个字符空间并删除|符号我该怎么办？谢谢。

How can do so?

Next question is that in the string suppose after 9 i have to make a single character space and remove | symbol how can i do so? Thanks.

1|2|3|4|5|6|7|8|9|1|2|3|4|5|6|7|8|9 

i：我如何删除字符并在确定数字或点后的数字之间添加空格

i:e how can i remove the character and add space between the number after a definite number or poin

推荐答案

有一个你可以做多少种方法，范围从简单化

There are a number of ways you can do it, ranging from the simplistic

MyString = MyString.Replace("9|1", "9 |1")

正如ryanb31所建议的，

通过使用MyString.IndexOf和MyString.SubString（谷歌和MSDN可以帮助你）：

as has been suggested by ryanb31,
through use of MyString.IndexOf and MyString.SubString (Google, and MSDN can help you with them):

Dim MyString As String = "1|2|3|4|5|6|7|8|9|1|2|3|4|5|6|7|8|9"
Dim index As Integer = MyString.IndexOf("9|1")
If index >= 0 Then
    Dim left As String = MyString.Substring(0, index)
    Dim right As String = MyString.Substring(index + 3)
    MyString = left & "9 |1" & right
End If

通过MyString.Split和String.Join（谷歌再次），到Regex（有关于此的全书）。



究竟哪个解决方案适合您，取决于太多因素：字符串的变量，您希望完成替换的次数，以及您需要将其设置为9 | 1的灵活性。

through MyString.Split and String.Join (Google again), to Regex (there are whole books about this).

Exactly which solution is right for you, depends on too many factors: how variable the string is, how many times you want the replacement done, and how flexible you need to be about it being "9|1".
