DataServiceCollection<T> Constructor (IEnumerable<T>, TrackingMode)

Creates a new instance of the DataServiceCollection<T> class based on query execution and with the specified tracking mode.

Namespace:  System.Data.Services.Client
Assembly:  System.Data.Services.Client (in System.Data.Services.Client.dll)

public DataServiceCollection(
	IEnumerable<T> items,
	TrackingMode trackingMode
)

Parameters

items
Type: System.Collections.Generic.IEnumerable<T>

A DataServiceQuery<TElement> or LINQ query that returns an IEnumerable<T> collection of objects that are used to initialize the collection.

trackingMode
Type: System.Data.Services.Client.TrackingMode

A TrackingMode value that indicated whether or not changes made to items in the collection are automatically tracked.

By default, automatic change tracking is enabled for a DataServiceCollection<T>. Use this class constructor and supply a value of None for trackingMode to create an instance of DataServiceCollection<T> that uses manual change tracking. When you use manual tracking, you must implement INotifyPropertyChanged and INotifyCollectionChanged and handle the raise events to manually report changes to the DataServiceContext.

The IEnumerable<T> collection of objects supplied for items is usually a query that returns the items in the collection. However, any IEnumerable<T> collection of the correct type can be supplied.
