InnerHtml in WebBrowser

Question

我需要InnerHtml的帮助。

​

​

我怎么知道这些颜色中的一种何时会变成绿色？需要具体说明。不是WebBrowser1.document.body.innertext.contains("Green")

所以，就像：

If WebBrowser1.Document.GetElementById("data-search_id ="1740").InnerText.Contains("background-color: Green;") Then
    Label1.Text = ("Working")
End if

这是行不通的，因为data-search_id ="1740"不是id。我认为应该是像InnerHtml data-search_id ="1740"和InnerText.contains之类的东西。

(这就是它绿色时的样子：background-color: Green;)

我试过几样东西。示例：

Dim allelements As HtmlElementCollection = WebBrowser1.Document.All

For Each webpageelement As HtmlElement In allelements
    If webpageelement.GetAttribute("data-search_id") = "1762".Contains("background-color: green;") Then
         Label1.Text = "Working"
    End If
Next

        Dim allelements As HtmlElementCollection = WebBrowser1.Document.GetElementsByTagName("tr")

        For Each webpageelement As HtmlElement In allelements
            Dim SearchID = webpageelement.GetAttribute("data-search_id")
            Dim Style As String = ""

            If webpageelement.Style IsNot Nothing Then
                Style = webpageelement.Style
            End If

            If SearchID = "1762" AndAlso Style.Contains("green") Then
                Label1.Text = "Working"
            End If
        Next
