XmlReader.MoveToNextAttribute Method


When overridden in a derived class, moves to the next attribute.

 abstract bool MoveToNextAttribute();
public abstract bool MoveToNextAttribute ();
abstract member MoveToNextAttribute : unit -> bool
Public MustOverride Function MoveToNextAttribute () As Boolean


true if there is a next attribute; false if there are no more attributes.


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 displays all attributes on the current node.

if (reader.HasAttributes) {
  Console.WriteLine("Attributes of <" + reader.Name + ">");
  while (reader.MoveToNextAttribute()) {
    Console.WriteLine(" {0}={1}", reader.Name, reader.Value);
  // Move the reader back to the element node.
If reader.HasAttributes Then
  Console.WriteLine("Attributes of <" + reader.Name + ">")
  While reader.MoveToNextAttribute()
    Console.WriteLine(" {0}={1}", reader.Name, reader.Value)
  End While
  ' Move the reader back to the element node.
End If


If the current node is an element node, this method is equivalent to MoveToFirstAttribute. If MoveToNextAttribute returns true, the reader moves to the next attribute; otherwise, the position of the reader does not change.
