<div style="color:Black;background-color:White; <pre>
<span style="color:Blue; private <span style="color:Blue; byte[] GetFile()
{
<span style="color:Blue; byte[] buffer = <span style="color:Blue; null;
<span style="color:Blue; using (FileStream fs = <span style="color:Blue; new FileStream(<span style="color:#A31515; @"C:MappersTest.xml", FileMode.Open))

<span style="color:Blue; private <span style="color:Blue; void DoWork()

<span style="color:Blue; byte[] xml = GetFile();


<span style="color:Blue; using (MemoryStream xmlDataStream = <span style="color:Blue; new MemoryStream())

xmlDataStream.Write(xml, 0, xml.Length);

<span style="color:Green; //Its failing Here with error...."Root element is missing"
XDocument xDoc = XDocument.Load(xmlDataStream);

<span style="color:Green; // Add processing instructions
xDoc.AddFirst(GetXslStyleSheetProcessingInstruction());

<span style="color:Green; // Save the stream
xDoc.Save(xmlDataStream);

<span style="color:Green; // Reset the stream to begining
xmlDataStream.Position = 0;

}
