Regex 对非共享成员的引用需要对象引用

我试图从列表框中删除一些文本，但一直出现此错误

Error   1   Reference to a non-shared member requires an object reference.  

这是导致错误的代码

ListBox1.Items.Add(Match.ToString.Replace("color: 0863BB;", "").Replace("</span>", "").Replace(">", "").Replace("""", ""))

公开课表格1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

    Dim Regex As New Regex("color: 0863BB;" & Chr(34) & ">(.*?)</span></span>")
    Dim Matches As MatchCollection = Regex.Matches(RichTextBox1.Text)

    For Each Match As Match In Matches

        ListBox1.Items.Add(Match.ToString)

    Next

End Sub

Private Sub Button2_Click(sender As System.Object, e As System.EventArgs) Handles Button2.Click
    'RichTextBox1.Text = WebBrowser1.DocumentText

End Sub

Private Sub RichTextBox1_TextChanged(sender As System.Object, e As System.EventArgs) Handles RichTextBox1.TextChanged
    ListBox1.Items.Add(Match.ToString.Replace("color: 0863BB;", "").Replace("</span>", "").Replace(">", "").Replace("""", ""))

结束类

编译器正在抱怨

匹配.ToString

ToString

是一种实例方法，但

Match

是一种类型
