    adsf 
    The text of the samp         


        

Answer 1

You'll have to use CDATA section. More specifically, create a XmlCDataSection using XmlDocument.CreateCDataSection and supply your string as a parameter.

Answer 2

Try this:

string s = "<xml><foo></foo></xml>";
XmlDocument xdoc = new XmlDocument();
xdoc.LoadXml(s);
xdoc.Save("myfilename.xml");

Has the added benefit that the load will fail if your XML is invalid.

Answer 3

I know you said C# but have you tried VB.NET for XML Literals. Amazing stuff.

Public Class Program
    Public Shared Sub Main()
        Dim myKeyBoardStyle = "dvorak"

        Dim myXML As XElement = <ROOT>
                                qwerty
                                <altKeyboard><%= myKeyBoardStyle.ToUpper() %></altKeyboard>
                                    <SampleElement>adsf</SampleElement>
                                    <SampleElement2>The text of the sample element2</SampleElement2>
                                </ROOT>

        Console.WriteLine(myXML.ToString())

        myXML.Save(".\fileFromXElement.xml")
    End Sub
End Class

Notice the neat element which injects the result of code in into the output:

<?xml version="1.0" encoding="utf-8"?>
<ROOT>
                                qwerty
                                <altKeyboard>DVORAK</altKeyboard><SampleElement>adsf</SampleElement><SampleElement2>The text of the sample element2</SampleElement2></ROOT>
