When overridden in a derived class, gets the number of attributes on the current node.
public:
abstract property int AttributeCount { int get(); };
public abstract int AttributeCount { get; }
member this.AttributeCount : int
Public MustOverride ReadOnly Property AttributeCount As Integer
The number of attributes on the current node.
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.
// 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
This property is relevant to Element
, DocumentType
and XmlDeclaration
nodes only. (Other node types do not have attributes.)
