ObjectQuery<T>.Execute(MergeOption) Method

public:
 System::Data::Objects::ObjectResult<T> ^ Execute(System::Data::Objects::MergeOption mergeOption);

public System.Data.Objects.ObjectResult<T> Execute(System.Data.Objects.MergeOption mergeOption);

override this.Execute : System.Data.Objects.MergeOption -> System.Data.Objects.ObjectResult<'T>

Public Function Execute (mergeOption As MergeOption) As ObjectResult(Of T)

Parameters

Returns

An ObjectResult<T> that contains a collection of entity objects returned by the query.

Examples

This example returns an ObjectResult<T> from Execute method. Then it gets an enumerator and iterates through the query results. At the end it releases the enumerator and the ObjectResult<T> object.

using (AdventureWorksEntities context =
 new AdventureWorksEntities())
{
 ObjectSet<Product> query = context.Products;
 ObjectResult<Product> queryResults = null;

 System.Collections.IEnumerator enumerator = null;
 try
 {
 queryResults = query.Execute(MergeOption.AppendOnly);

 // Get the enumerator.
 enumerator = ((System.Collections.IEnumerable)queryResults).GetEnumerator();

 // Iterate through the query results.
 while (enumerator.MoveNext())
 {
 Product product = (Product)enumerator.Current;
 Console.WriteLine("{0}", product.Name);
 }
 // Dispose the enumerator
 ((IDisposable)enumerator).Dispose();
 }
 finally
 {
 // Dispose the query results and the enumerator.
 if (queryResults != null)
 {
 queryResults.Dispose();
 }
 if (enumerator != null)
 {
 ((IDisposable)enumerator).Dispose();
 }
 }
}

Remarks

The default merge option for object queries is AppendOnly. For more information, see Identity Resolution, State Management, and Change Tracking.
