Create a XML Schema (C#) using Visual Studio Express 2012

Question

How do I add an XML schema to my xml file?
Here is my code:
private void WriteXmlToFile(DataSet dsDataSet)
if (dsDataSet == null) { return; }
// Create a file name to write to - creates a string
string xmlfilename = @"C:\Users\fenwky\XmlDoc.xml";
// Create the FileStream to write with.
System.IO.FileStream stream = new System.IO.FileStream
(xmlfilename, System.IO.FileMode.Create);
// Create an XmlTextWriter with the fileStream.
System.Xml.XmlTextWriter xmlWriter =
new System.Xml.XmlTextWriter(stream,
System.Text.Encoding.Unicode);
// Write dsDataSet to the file with the WriteXml method.
dsDataSet.WriteXml(xmlWriter);
xmlWriter.Close();
And here is my xml:
<NewDataSet>
<Table1>
<Item_Code>A0001</Item_Code>
<Item_Description>Wheels, Horse on</Item_Description>
<Current_Count>5</Current_Count>
<On_Order>No</On_Order>
</Table1>
<Table1>
<Item_Code>A0002</Item_Code>
<Item_Description>Wheels, Elephant on</Item_Description>
<Current_Count>2</Current_Count>
<On_Order>No</On_Order>
</Table1>
<Table1>
<Item_Code>A0003</Item_Code>
<Item_Description>Wheels, Dog on</Item_Description>
<Current_Count>0</Current_Count>
<On_Order>Yes</On_Order>
</Table1>

Open the XML with NOTEPAD to see if you are getting the correct results. Something may be wrong with you CSV file.  Get original CSV that teacher gave out.  Here is my results and C# code.  The styling is the 2nd line and simply
requires changing the one line in the C# that outputs the line.
<?xml version="1.0" encoding="UTF-8"?>
