XmlReader.MoveToNextAttribute Method

Definition

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

C#
public abstract bool MoveToNextAttribute ();

Returns

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

Exceptions

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.

C#
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.
  reader.MoveToElement();
}

Remarks

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.
