Exceptions

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."

Examples

The following example displays all attributes on the current node.

// Display all attributes.
if (reader.HasAttributes) {
  Console.WriteLine("Attributes of <" + reader.Name + ">");
  for (int i = 0; i < reader.AttributeCount; i++) {
    Console.WriteLine("  {0}", reader[i]);
  }
  // Move the reader back to the element node.
  reader.MoveToElement();
}

' Display all attributes.
If reader.HasAttributes Then
  Console.WriteLine("Attributes of <" + reader.Name + ">")
  Dim i As Integer
  For i = 0 To (reader.AttributeCount - 1)
    Console.WriteLine("  {0}", reader(i))
  Next i
  ' Move the reader back to the element node.
  reader.MoveToElement() 
End If

Remarks

This property is relevant to Element, DocumentType and XmlDeclaration nodes only. (Other node types do not have attributes.)
