引用非共享成員需要一個對象引用

Question

我想從列表框中刪除一些文本，並且不斷收到此錯誤。

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

下面是導致錯誤的代碼。

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

這是我下面的完整代碼。 我不知道我在做什麼錯，請幫助。

Imports System.Text.RegularExpressions 

公共類Form1中

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("""", "")) 
End Sub 

Private Sub Button3_Click(sender As System.Object, e As System.EventArgs) Handles Button3.Click 
    If ListBox1.Items.Contains("<span>") Then 

    End If 
End Sub 

Private Sub ListBox1_SelectedIndexChanged(sender As System.Object, e As System.EventArgs) Handles ListBox1.SelectedIndexChanged 
    ' (Match.ToString.Replace("color: 0863BB;", "").Replace("</span>", "").Replace(">", "").Replace("""", "")) 
End Sub

編譯器抱怨Match.ToString。 ToString是一種實例方法，但Match是一種類型。
