XmlReader.AttributeCount Property

.NET Framework 4.5

When overridden in a derived class, gets the number of attributes on the current node.

Namespace:  System.Xml
Assembly:  System.Xml (in System.Xml.dll)
C#
C++
F#
VB
Copy 
public abstract int AttributeCount { get; }

Property Value

Type: System.Int32
The number of attributes on the current node.
ExceptionCondition
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.”

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

The following example displays all attributes on the current node.

C#
VB
Copy 
// 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(); 
}
