使用StreamReader文本中的XElement创建新的XDocument

Question

I'm trying to take an existing XML file and "embed" that into another node of another "Root" XML file. Suppose there's a path to an existing xml file...

 StreamReader reader = new StreamReader(path);

    string lines = reader.ReadLine();
    while (!reader.EndOfStream)
    {
        lines = reader.ReadLine();
    }

    XDocument doc = new XDocument(
        new XComment("You can copy and paste or open the XML in Excel."),
        new XElement("Root",
            new XElement("logs",lines))
    );

I end up with things like this:

<Root><logs>&lt;log&gt;&lt;username&gt;otonomy&lt;/

Some decode encode help needed.

Answer 1

Use XElement.Load() static method instead:

XDocument doc = new XDocument(
        new XComment("You can copy and paste or open the XML in Excel."),
        new XElement("Root",
            new XElement("logs"
                XElement.Load(path)))
    );

It can take the path directly, so you don't have to deal with StreamReader at all.

Answer 2

Try:

string lines = File.ReadAllText( path );

XDocument doc = new XDocument(
    new XComment( "You can copy and paste or open the XML in Excel." ),
    new XElement( "Root",
        new XElement( "logs", XElement.Parse( lines ) ) ) );
