Read XML File

12-24-2007 12:51 PM |

Hello,

How I can read a XML File in Silverlight?

I try:

XmlReader bddXML = XmlReader.Create(new StreamReader("path_to_my_xmlfile));

bddXML.Read();

But I get an Exception :(

The XML File is in my project.

Thank a lot

Read it like this：
                Uri requestUri = new Uri("path_to_my_xmlfile", UriKind.Relative);
                HttpWebRequest request = new BrowserHttpWebRequest(requestUri);
                request.Connection = "Close";
                HttpWebResponse response = request.GetResponse();
                if (response.StatusCode == HttpStatusCode.OK)
                {
                    responseStatus = HttpStatusCode.OK;
                    Stream content = response.GetResponseStream();
                    XmlReader reader = XmlReader.Create(new StreamReader(content, Encoding.UTF8));
                    while (reader.Read())
                    {
                        // your code here
                    }

I get an exception on the line:

HttpWebResponse response = request.GetResponse();

Operation is not valid due to the current state of the object.

We are obliged to use an HttpWebRequest to access a local file?

Thank

For local file, you can try this:

Stream s = this.GetType().Assembly.GetManifestResourceStream("LoadXml.your_xml_file.xml");
using (XmlReader reader = XmlReader.Create(s))
{
    while (reader.Read())
    {
        //your codes here
    }
}

For more information about GetManifestResourceStream, you can check it in MSDN.

Thank for your answer.

When I do that, s is null, so, the XML File must have a specific characteristic ?

The path must be: LoadXml.my_file.xml or LoadXml.C:\\myproject\\myfile.xml ?

Lol I'm a newbee... :p

I thought LoadXml was a keyword for GetManifestResourceStream(), so it's the Namespace!!!

I change LoadXML by my Namespace and it's work fine!

Thanks

Hi.. I tried to read an xml file stored in a location say "c:\". But the GetManifestResourceStream() always returns null.

Cant I read a file external to the project?

my code:

Stream s = this.GetType().Assembly.GetManifestResourceStream("SilverlightProject2.c:\\LiveUpdateLog.xml");using (XmlReader reader = XmlReader.Create(s))

{

while (reader.Read())

{

}

where SilverlightProject2 is my namespace name.

hi,

you can't read files from the file system ... this is a security issue.
