I want to save and load my xml data using XmlReader. But I don't know how to use this class. Can you give me a sample code for start?

This method allows you add additional features to an underlying XmlReader object. The underlying XmlReader object can be another XmlReader object created by the Create method, or an XmlReader object created using one of the concrete XmlReader implementations.
XmlDocument is very easy to use. Its only real drawback is that it loads the whole XML document into memory to process. Its seductively simple to use. XmlReader is a stream based reader so will keep your process memory utilization generally flatter but is more difficult to use.
View an XML file in a browserIn Chrome, just open a new tab and drag the XML file over. Alternatively, right click on the XML file and hover over "Open with" then click "Chrome". When you do, the file will open in a new tab. Note: Instructions for your operating system may differ slightly.
XmlTextReader provides forward-only, read-only access to a stream of XML data. The current node refers to the node on which the reader is positioned. The reader is advanced using any of the read methods and properties reflect the value of the current node.
MSDN has a simple example to get you started here.
If you're interested in reading and writing XML documents, and not just specifically using the XmlReader class, there's a nice article covering a few of your options here.
But if you just want to get started and play around, try this:
XmlReaderSettings settings = new XmlReaderSettings();
settings.IgnoreWhitespace = true;
settings.IgnoreComments = true;
XmlReader reader = XmlReader.Create("file.xml", settings);
