我正面临如下所示的异常错误

用于解析的代码是 
            string url1 = "http://maps.googleapis.com/maps/api/geocode/xml?address=Bangalore&sensor=false";

            XDocument doc = XDocument.Parse(url1);
            var lat = doc.Descendants(XName.Get("lat", url1)).FirstOrDefault();
            result.Text = (string)lat;

我面对的错误行XDocument.Parse(url1);你能帮我克服这个例外吗，因为我是这个领域的新手

使用visual studio IDE在c#中解析XML错误

XDocument.Parse(str)是解析参数string in parse method。和XDocument。加载方式是指加载a file in your XAP package。但是您想从网站加载XML文件。您可以向url发送请求并读取响应，然后对其进行解析。这样的:

string url1 = "http://maps.googleapis.com/maps/api/geocode/xml?address=Bangalore&sensor=false";
string content = await HttpHelper.GetResponse(url1);
XDocument doc = XDocument.Parse(content);
var lat = doc.Descendants(XName.Get("lat")).FirstOrDefault();
result.Text = (string)lat;

getResponse方法:

public async static Task<string> GetResponse(string url)
{
    try
    {
        WebRequest request = HttpWebRequest.Create(url);
        request.ContentType = "application/xml";
        WebResponse response = await request.GetResponseAsync();
        StreamReader reader = new StreamReader(response.GetResponseStream());
        string content = reader.ReadToEnd();
        reader.Dispose();
        response.Dispose();
        return content;
    }
    catch
    {
        return "";
    }
}

试试这个

string url1 = "http://maps.googleapis.com/maps/api/geocode/xml?address=Bangalore&sensor=false";
string content = await HttpHelper.GetResponse(url1);
XDocument doc = XDocument.Parse(content);
var lat = doc.Descendants(XName.Get("lat")).FirstOrDefault();
result.Text = (string)lat;
