HTML AGILITY PACK：使用Proxies？

題
如何在HAP中使用代理？這就是我到目前為止......（沒有運氣）。
IPCHICKEN只是用來測試IP地址。它顯示我的IP地址，而不是我的代理的IP地址
Function GetPrice(ByVal AmazonURL As String, ByVal Delay As Integer)
Dim aHtml As New HtmlWeb
Dim ChromeAgent As String = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/536.11 (KHTML, like Gecko) Chrome/20.0.1132.57 Safari/536.11"
aHtml.UserAgent = ChromeAgent
Dim proxy As New System.Net.WebProxy
Dim proxyAddress As New Uri("http://111.111.111/")
Dim aDoc As HtmlDocument = aHtml.Load("http://www.ipchicken.com", "GET", proxy, System.Net.CredentialCache.DefaultCredentials)
Dim aNode As HtmlAgilityPack.HtmlNode
aNode = aDoc.DocumentNode.SelectSingleNode("//div[@id='olpDivId']/span[2]")
If aNode.InnerText Is Nothing Then
End If
Dim UsedPrice1 As String = aNode.InnerText
Dim i As Integer = UsedPrice1.IndexOf("$")
Dim UsedPrice As Integer = UsedPrice1.Substring(i + 1)
System.Threading.Thread.Sleep(Delay)
Return UsedPrice
End Function

也許嘗試類似以下內容。根據頁面的不同，您可能不需要UTF8轉換。
WebProxy proxy = new WebProxy("proxyname", 8080);
proxy.Credentials = CredentialCache.DefaultCredentials;
WebClient client = new WebClient();
client.Proxy = proxy;
string baseHtml = "";
byte[] pageContent = client.DownloadData("your target url");
UTF8Encoding utf = new UTF8Encoding();
baseHtml = utf.GetString(pageContent);
HtmlDocument pageHtml = new HtmlDocument();
pageHtml.LoadHtml(baseHtml);
