Question

I use the StreamReader class to obtain XML for my GeoCoding process from Google.

StreamReader srGeoCode = new StreamReader(WebRequest.Create(Url).GetResponse().GetResponseStream());
String GeoCodeXml = srGeoCode.ReadToEnd();
XmlDocument XmlDoc = new XmlDocument();
GeoCode oGeoCode = new GeoCode();
XmlDoc.Load(GeoCodeXml);

I get XML back but it adds \n and other extras to the XML

<?xml version=\"1.0\" encoding=\"UTF-8\" ?>\n<kml xmlns=\"http://earth.google.com/kml/2.0\"><Response>\n  <name>

I have the same code in VB and it does not do this. I can successfully GeoCode my information using the VB version of this console app.

Is there a reason the C# version adds this extra data to the XML that I retrieve back? I am trying my best to convert everything over to C#. I enjoy coding in it over VB.

Here is the VB Code:

    Dim wreqGeoCode As WebRequest = WebRequest.Create(strURL)
    Dim wresGeoCode As WebResponse = wreqGeoCode.GetResponse
    Dim srGeoCode As New StreamReader(wresGeoCode.GetResponseStream())
    Dim strXML As String = srGeoCode.ReadToEnd()
    Dim xmlDoc As New XmlDocument
    xmlDoc.LoadXml(strXML)

You need XmlDoc.LoadXml if you’re going to load a string. Load loads from a file.

BTW, the alternative is also more efficient. You can load the document directly from the stream:

WebRequest webRequest = WebRequest.Create(Url);
using (WebResponse webResponse = webRequest.GetResponse())
{
    using (Stream responseStream = webResponse.GetResponseStream())
    {
        XmlDocument XmlDoc = new XmlDocument();
        GeoCode oGeoCode = new GeoCode();
        XmlDoc.Load(responseStream);
    }
}

The using statements ensure that the WebResponse and Stream get cleaned up, even if an exception is thrown.
