Question

我想读到因特网上的XML文件,以备数据。 The XML file is here:

如果是:

public DataTable GetCurrentFxPrices(string url)
{
    WebProxy wp = new WebProxy("http://mywebproxy:8080", true);
    wp.Credentials = CredentialCache.DefaultCredentials;
    WebClient wc = new WebClient();
    wc.Proxy = wp;
    MemoryStream ms = new MemoryStream(wc.DownloadData(url));
    DataSet ds = new DataSet("fxPrices");
    ds.ReadXml(ms);
    DataTable dt = ds.Tables["Rate"];
    return dt;
}

罚款。我在努力如何使用因特网探索者中设定的默认代理。我不想硬化代理人。如果互联网探索者没有指定代理,我也希望该守则发挥作用。

Answer 1

你们可以使用康索尔。写作Line(System.Net.WebProxy.GetDefaultProxy(). Address.AbsoluteUri;......

Answer 2

在您的信中添加以下文字:

<system.net>
    <defaultProxy useDefaultCredentials="true"/>
</system.net>

Answer 3

#region Function to get x-rate via proxy
public string fncProxyGetRate(string countryCode)// use  GBP  for British Pounds
{
    string rtnTxt = "";
    try
    {
        string url = "http://rss.timegenie.com/forex.xml";
        string proxyUrl = "http://xxx.xxx.x.x:8080/";
        string myXratePath = "/forex/data/code[text()= " + countryCode + " ]";

        WebProxy wp = new WebProxy(proxyUrl, true);
        wp.Credentials = CredentialCache.DefaultCredentials;
        WebClient wc = new WebClient();
        wc.Proxy = wp;

        MemoryStream ms = new MemoryStream(wc.DownloadData(url));
        XmlTextReader rdr = new XmlTextReader(ms);

        XmlDocument doc = new XmlDocument();
        doc.Load(rdr);

        rtnTxt = doc.SelectSingleNode(myXratePath).ParentNode.SelectSingleNode("rate").InnerXml;
    }
    catch (Exception ex)
    {
        rtnTxt = ex.Message;
    }
    return rtnTxt;
} 
#endregion
