| Exception | Condition |

| InvalidOperationException | An XmlReader method was called before a previous asynchronous operation finished. In this case, InvalidOperationException is thrown with the message “An asynchronous operation is already in progress.” |
The following example reads an XML file and displays each of the nodes.
reader.MoveToContent(); // Parse the file and display each of the nodes. while (reader.Read()) { switch (reader.NodeType) { case XmlNodeType.Element: Console.Write("<{0}>", reader.Name); break; case XmlNodeType.Text: Console.Write(reader.Value); break; case XmlNodeType.CDATA: Console.Write("<![CDATA[{0}]]>", reader.Value); break; case XmlNodeType.ProcessingInstruction: Console.Write("<?{0} {1}?>", reader.Name, reader.Value); break; case XmlNodeType.Comment: Console.Write("<!--{0}-->", reader.Value); break; case XmlNodeType.XmlDeclaration: Console.Write("<?xml version='1.0'?>"); break; case XmlNodeType.Document: break; case XmlNodeType.DocumentType: Console.Write("<!DOCTYPE {0} [{1}]", reader.Name, reader.Value); break; case XmlNodeType.EntityReference: Console.Write(reader.Name); break; case XmlNodeType.EndElement: Console.Write("</{0}>", reader.Name); break; } }
The sample uses the items.xml file.
<?xml version="1.0"?> <!-- This is a sample XML document --> <!DOCTYPE Items [<!ENTITY number "123">]> <Items> <Item>Test with an entity: &number;</Item> <Item>Test with a child element <more/> stuff</Item> <Item>Test with a CDATA section <![CDATA[<456>]]> def</Item> <Item>Test with a char entity: A</Item> <!-- Fourteen chars in this element.--> <Item>1234567890ABCD</Item> </Items>
