我正在尝试编写一个代码来从某个网站下载一部电影，而我却一直试图将这个值放到文本框中，但是这段代码的其余部分已经完成了，所以我想，没有别的问题。所以这是来自网站的代码：`

如果这是必要的话，它可能是完整的4行。
我一直在寻找最近5个小时的解决方案，我找不到任何有用的东西......

快速而肮脏的方法是：
1）使用以下代码将网页的HTML内容下载到字符串中：
Dim htmlContent As String = New System.Net.WebClient().DownloadString(<Enter URL Here>)
2）...然后在字符串中搜索您的代码。一种方法是先在HTML中的哪个位置找到字符串＆＃34; http://stream.streamo.tv/?scode=＆＃34;位于......
Dim codeLocation As Integer = htmlContent.IndexOf("http://stream.streamo.tv/?scode=")
然后浏览每个后续角色，逐个角色地构建代码，直到找到终止角色（例如＆＃34;＆amp;＆＃34;）。
我假设此代码仅在页面上出现一次。如果没有，您将需要找到一种循环每个实例的方法（这并不困难，但这里没有涉及）。

也许它会起作用，但它是html代码的动态部分，因此页面源中没有链接，只有选择“inspect element”函数才能找到它...
我试图做这样的事情，但我找不到工作解决方案......：
1如果我这样做：
For Each h As HtmlElement In WebBrowser1.Document.GetElementsByTagName("value")
If Not Object.ReferenceEquals(h.GetAttribute("name"), Nothing) AndAlso h.GetAttribute("name").Equals("flashvars") Then
Tbox1.Text = h.InnerText
Exit For
End If
Next
然后我可以在这里设置数据：
(...).SetAttribute("Value", TextBox4.Text)
但我不知道如何扭转这种情况并将其转换为文本框：
<param name="flashvars" value="here"></param>
