System.Xml.Serialization.XmlArrayItemAttributes Class

Summary

Represents a collection of XmlArrayItemAttribute objects.

C# Syntax:

public class XmlArrayItemAttributes : CollectionBase

The XmlArrayItemAttributes class allows you to specify the derived types that can be inserted into an array returned by a public field or public read/write property.

An instance of this class is returned by the XmlAttributes.XmlArrayItems property of the XmlAttributes class. The XmlAttributes class is used when overriding the set of XmlArrayItemAttribute objects that can be inserted into an array to which the XmlArrayAttribute has been applied.

For each new type you want the field or property to accept, create an XmlArrayItemAttribute and use the XmlArrayItemAttributes.Add to to add the object to the XmlArrayItemAttributes collection returned by the XmlAttributes.XmlArrayItems property. XmlAttributeOverrides.Add the XmlAttributes to an XmlAttributeOverrides, specifying the type of the object containing the field or property, and the name of the field or property. Construct an XmlSerializer with the XmlAttributeOverrides before calling the XmlSerializer.Serialize or XmlSerializer.Deserialize method.

Summary

Returns an enumerator that can iterate through the CollectionBase instance.

C# Syntax:

public IEnumerator GetEnumerator();

Return Value:

An IEnumerator for the CollectionBase instance.

Implements:

IEnumerable.GetEnumerator

Enumerators only allow reading the data in the collection. Enumerators cannot be used to modify the underlying collection.

Initially, the enumerator is positioned before the first element in the collection. IEnumerator.Reset also brings the enumerator back to this position. At this position, calling IEnumerator.Current throws an exception. Therefore, you must call IEnumerator.MoveNext to advance the enumerator to the first element of the collection before reading the value of IEnumerator.Current.

IEnumerator.Current returns the same object until either IEnumerator.MoveNext or IEnumerator.Reset is called. IEnumerator.MoveNext sets IEnumerator.Current to the next element.

After the end of the collection is passed, the enumerator is positioned after the last element in the collection, and calling IEnumerator.MoveNext returns false. If the last call to IEnumerator.MoveNext returned false, calling IEnumerator.Current throws an exception. To set IEnumerator.Current to the first element of the collection again, you can call IEnumerator.Reset followed by IEnumerator.MoveNext.

An enumerator remains valid as long as the collection remains unchanged. If changes are made to the collection, such as adding, modifying or deleting elements, the enumerator is irrecoverably invalidated and the next call to IEnumerator.MoveNext or IEnumerator.Reset throws an InvalidOperationException. If the collection is modified between IEnumerator.MoveNext and IEnumerator.Current, IEnumerator.Current will return the element that it is set to, even if the enumerator is already invalidated.

The enumerator does not have exclusive access to the collection; therefore, enumerating through a collection is intrinsically not a thread-safe procedure. Even when a collection is synchronized, other threads could still modify the collection, which causes the enumerator to throw an exception. To guarantee thread safety during enumeration, you can either lock the collection during the entire enumeration or catch the exceptions resulting from changes made by other threads.

Summary

Performs additional custom processes when clearing the contents of the CollectionBase instance.

C# Syntax:

protected virtual void OnClear();

The default implementation of this method is intended to be overridden by a derived class to perform some action before the collection is cleared.

The On* methods are invoked only on the instance returned by the CollectionBase.List property, but not on the instance returned by the CollectionBase.InnerList property.

Notes to implementors:

This method allows implementers to define processes that must be performed before deleting all the elements from the underlying ArrayList. By defining this method, implementers can add functionality to inherited methods without having to override all other methods.

CollectionBase.OnClear is invoked before the standard Clear behavior, whereas CollectionBase.OnClearComplete is invoked after the standard Clear behavior.

For example, implementers can exempt certain elements from deletion by a global Clear.

Summary

Performs additional custom processes when validating a value.

C# Syntax:

protected virtual void OnValidate(    object value );

value

The default implementation of this method determines whether value is null, and, if so, throws ArgumentNullException. It is intended to be overridden by a derived class to perform additional action when the specified element is validated.

The On* methods are invoked only on the instance returned by the CollectionBase.List property, but not on the instance returned by the CollectionBase.InnerList property.

Inherited
See base class member description: System.Collections.CollectionBase.RemoveAt

Summary

Removes the element at the specified index of the CollectionBase instance.

C# Syntax:

index

The zero-based index of the element to remove.

Exceptions

Exception Type	Condition
ArgumentOutOfRangeException	index is less than zero. -or- index is equal to or greater than CollectionBase.Count.

Implements:

IList.RemoveAt

In collections of contiguous elements, such as lists, the elements that follow the removed element move up to occupy the vacated spot. If the collection is indexed, the indexes of the elements that are moved are also updated. This behavior does not apply to collections where elements are conceptually grouped into buckets, such as a hashtable.
