Question

与How to remove double white space character using regexp?

相同

但是对于vb.net

怎么做？

Answer 1

Dim text = "My         name      is          Anas                 Fares"
Dim newText = System.Text.RegularExpressions.Regex.Replace(text, "[ ]{2,}", " ")

如果你想摆脱TABS，NEWLINES等等，还是这个。

Dim text = "My         name      is      " & Environment.NewLine & "    Anas                 Fares"
Dim newText = System.Text.RegularExpressions.Regex.Replace(text, "\s+", " ")

Answer 2

你只需要在双白空间上替换一个空格：

Dim str = "Lorem  Ipsum  Dolar"
str = str.replace("  ", " ")
return str 'Lorem Ipsum Dolar

但您仍然可以在VB.NET中使用与链接中的javascript代码中使用的相同的正则表达式。本文展示了一种方法：

Dim input As String = "This is   text with   far  too   much   " + _
                            "whitespace."
Dim pattern As String = "\s+"
Dim replacement As String = " "
Dim rgx As New Regex(pattern)
Dim result As String = rgx.Replace(input, replacement)

Console.WriteLine("Original String: {0}", input)
Console.WriteLine("Replacement String: {0}", result)

Answer 3

直接转换是：

Dim r As Regex = New Regex("\s{2,}") 'or " {2,}" or "[ ]{2,}", depending on if you want whitespace, or just spaces.
Dim stringWithDoubleSpaces As String = "this  is  a double  spaced  string"
Dim stringWithSingleSpaces As String = r.Replace(stringWithDoubleSpaces, " ")
