问题描述

我做加载实时XML文件（活URL）来的XmlDataDocument的任务，但每次我得到错误时间：

I am doing task of loading the live xml file (from live url) to XmlDataDocument, but every time I am getting error:

该操作已超时

在code是如下，包含XML的URL饲料，我希望将其加载到xmlDoc中。

The code is as follows, The url containing the xml feeds , I want to load it into xmlDoc.

XmlDataDocument xmlDoc = new XmlDataDocument();
xmlDoc.Load("http://www.globalgear.com.au/productfeed.xml");

请提出任何解决办法。

推荐答案

不要使用直接的XmlDataDocument类的Load方法;你几乎没有办法影响的行为，当涉及到长时间运行的HTTP请求。​​

Don't use the Load method of the XmlDataDocument class directly; you have little to no way of influencing the behaviour when it comes to long running HTTP requests.

相反，使用HttpWebRequest和HttpWebResponse类做的工作给你，然后加载后续响应到文档中。

Instead, use the HttpWebRequest and HttpWebResponse classes to do the work for you, and then load the subsequent response into your document.

例如：

    HttpWebRequest rq = WebRequest.Create("http://www.globalgear.com.au/productfeed.xml") as HttpWebRequest;
    //60 Second Timeout
    rq.Timeout = 60000;
    //Also note you can set the Proxy property here if required; sometimes it is, especially if you are behind a firewall - rq.Proxy = new WebProxy("proxy_address");
    HttpWebResponse response = rq.GetResponse() as HttpWebResponse;


    XmlTextReader reader = new XmlTextReader(response.GetResponseStream());

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

我测试过这个code在本地的应用程序实例和XmlDocument的填充了从您的网址中的数据。

I've tested this code in a local app instance and the XmlDocument is populated with the data from your URL.

您也可以在替换为的XmlDataDocument的XmlDocument在上面的例子 - 我preFER使用XmlDocument的，因为它不是（还）标记为已过时。

You can also substitute in XmlDataDocument for XmlDocument in the example above - I prefer to use XmlDocument as it's not (yet) marked as obsolete.

我在一个函数包装这个给你：

I've wrapped this in a function for you:

public XmlDocument GetDataFromUrl(string url)
{
    XmlDocument urlData = new XmlDocument();
    HttpWebRequest rq = (HttpWebRequest)WebRequest.Create(url);

    rq.Timeout = 60000;

    HttpWebResponse response = rq.GetResponse() as HttpWebResponse;

    using (Stream responseStream = response.GetResponseStream())
    {
        XmlTextReader reader = new XmlTextReader(responseStream);
        urlData.Load(reader);
    }

    return urlData;

}

要获取使用：

XmlDocument document = GetDataFromUrl("http://www.globalgear.com.au/productfeed.xml");
