请问在正则表达式中如何输入“"”

[herodraw]

就是引号
直接输入好像不行呀

[helloworld84]

输入两个 "" 会显示出 "

[淡蓝色2]

用\022,或者两个连续的双引号
例:搜索用双引号括起来的内容用下面的正则表达式:
Dim r As New Regex("\042\w+\042")
或
Dim r as New Regex("""w+""")

他们的效果是一模一样的

[jdsuchen]

"""" 相当于 “"”

[9sun888]

vb.net 用""
C# 用\"

[herodraw]

Dim reg As New Regex("<A href=(?<1>""index\.asp[^>]*)>(?<2>[^<]*)<\/A>")
Dim reg1 As New Regex("<[^>]*主题贴数[^>]*>(?<3>[^<]*)</TD>[^<]*<[^>]*><[^>]*发贴总数[^>]*>(?<4>[^<]*)</TD>")


Dim mc As MatchCollection = reg.Matches(Me.TextBox1.Text)
Dim mc1 As MatchCollection = reg1.Matches(Me.TextBox1.Text)


Dim m As Match
For Each m In mc
MsgBox(m.Groups("1").ToString)
MsgBox(m.Groups("2").ToString)
Next

For Each m In mc1

If m.Groups("4").Value <> "" Then
MsgBox(m.Groups("3").ToString)
MsgBox(m.Groups("4").ToString)

End If

Next
