Definition

Creates an equivalent object query that returns the related object.

public:
 System::Data::Objects::ObjectQuery<TEntity> ^ CreateSourceQuery();
public System.Data.Objects.ObjectQuery<TEntity> CreateSourceQuery ();
override this.CreateSourceQuery : unit -> System.Data.Objects.ObjectQuery<'Entity (requires 'Entity : null)>
Public Function CreateSourceQuery () As ObjectQuery(Of TEntity)
Returns
ObjectQuery<TEntity>

An ObjectQuery<T> that returns the related object.

Exceptions

When the object is in an Added state.

-or-

When the object is in a Detached state with a MergeOption other than NoTracking.

Remarks

This method is used to obtain a new instance of ObjectQuery<T> that, when it is executed, returns the related object. This is useful as the starting point for a more complex join, union, or filtered query, or to return the referenced object in a detached state using the NoTracking option.
