原帖作者要用正则取

引号中的字符/.

解决方案:

取一个match

        Imports System.Text.RegularExpressions

        Dim str As String = "g19='0.028' g20='3' g21='1' g22='24.1' g23='10.8'"
        Dim reg As New Regex("'([^']*)'")
        Dim m As Match = reg.Match(str)
        If m.success Then
            MsgBox(m.Groups(0).ToString)
        End If

只能取到第一个匹配的.

取多个match

        Dim str As String = " g16='.03' g17='29.886' g18='0.022'"
        Dim reg As New System.Text.RegularExpressions.Regex("'([^']*)'")
        Dim m As System.Text.RegularExpressions.MatchCollection = reg.Matches(str)
        For Each Match In m
            ListBox1.Items.Add(Match.ToString)
        Next
