示例1: AdventureWorksEntities
Using context As New AdventureWorksEntities()
Dim query As ObjectSet(Of Product) = context.Products
Dim queryResults As ObjectResult(Of Product) = Nothing
Dim enumerator As System.Collections.IEnumerator = Nothing
Try
queryResults = query.Execute(MergeOption.AppendOnly)
' Get the enumerator.
enumerator = DirectCast(queryResults, System.Collections.IEnumerable).GetEnumerator()
' Iterate through the query results.
While enumerator.MoveNext()
Dim product As Product = DirectCast(enumerator.Current, Product)
Console.WriteLine("{0}", product.Name)
End While
' Dispose the enumerator
DirectCast(enumerator, IDisposable).Dispose()
Finally
' Dispose the query results and the enumerator.
If queryResults IsNot Nothing Then
queryResults.Dispose()
End If
If enumerator IsNot Nothing Then
DirectCast(enumerator, IDisposable).Dispose()
End If
