XmlReader.Close Method
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
When overridden in a derived class, changes the ReadState to Closed.
Namespace: System.Xml
Assembly: System.Xml (in System.Xml.dll)
Syntax
Public Overridable Sub Close
public virtual void Close()
Remarks
This method also releases any resources held during reading. If Close has already been called, no action is performed.
Examples
The following example navigates through the stream to determine the current node type, and then uses XmlWriter to output the XmlReader content.
Dim output As StringBuilder = New StringBuilder()
Dim xmlString As String = "<?xml version='1.0'?>" & _
"<!-- This is a sample XML document -->" & _
"<Items>" & _
"<Item>test with a child element <more/> stuff</Item>" & _
"</Items>"
' Create an XmlReader
Using reader As XmlReader = XmlReader.Create(New StringReader(xmlString))
Dim ws As XmlWriterSettings = New XmlWriterSettings()
ws.Indent = True
Using writer As XmlWriter = XmlWriter.Create(output, ws)
' Parse the file and display each of the nodes.
While reader.Read()
Select Case reader.NodeType
Case XmlNodeType.Element
writer.WriteStartElement(reader.Name)
Case XmlNodeType.Text
writer.WriteString(reader.Value)
Case XmlNodeType.XmlDeclaration
Case XmlNodeType.ProcessingInstruction
writer.WriteProcessingInstruction(reader.Name, reader.Value)
Case XmlNodeType.Comment
writer.WriteComment(reader.Value)
Case XmlNodeType.EndElement
writer.WriteFullEndElement()
End Select
End While
End Using
End Using
OutputTextBlock.Text = output.ToString()
StringBuilder output = new StringBuilder();
String xmlString =
@"<?xml version='1.0'?>
<!-- This is a sample XML document -->
<Items>
<Item>test with a child element <more/> stuff</Item>
</Items>";
// Create an XmlReader
using (XmlReader reader = XmlReader.Create(new StringReader(xmlString)))
{
XmlWriterSettings ws = new XmlWriterSettings();
ws.Indent = true;
using (XmlWriter writer = XmlWriter.Create(output, ws))
{
// Parse the file and display each of the nodes.
while (reader.Read())
{
switch (reader.NodeType)
{
case XmlNodeType.Element:
writer.WriteStartElement(reader.Name);
break;
case XmlNodeType.Text:
writer.WriteString(reader.Value);
break;
case XmlNodeType.XmlDeclaration:
case XmlNodeType.ProcessingInstruction:
writer.WriteProcessingInstruction(reader.Name, reader.Value);
break;
case XmlNodeType.Comment:
writer.WriteComment(reader.Value);
break;
case XmlNodeType.EndElement:
writer.WriteFullEndElement();
break;
}
}
}
}
OutputTextBlock.Text = output.ToString();
