示例1: AdventureWorksEntities
Using context As New AdventureWorksEntities()
Dim queryString As String = "SELECT VALUE product FROM AdventureWorksEntities.Products AS product"
Dim productQuery1 As New ObjectQuery(Of Product)(queryString, context, MergeOption.NoTracking)
Dim productQuery2 As ObjectQuery(Of Product) = productQuery1.Top("2")
' Iterate through the collection of Product items.
For Each result As Product In productQuery2
Console.WriteLine("{0}", result.Name)
Next
End Using示例2: AdventureWorksEntities
Using context As New AdventureWorksEntities()
' Define the parameters used to define the "page" of returned data.
Dim skipValue As Integer = 3
Dim limitValue As Integer = 5
' Define a query that returns a "page" or the full
' Product data using the Skip and Top methods.
' When Top() follows Skip(), it acts like the LIMIT statement.
Dim query As ObjectQuery(Of Product) = _
context.Products.Skip("it.ListPrice", "@skip", _
New ObjectParameter("skip", skipValue)).Top("@limit", New ObjectParameter("limit", limitValue))
' Iterate through the page of Product items.
For Each result As Product In query
Console.WriteLine("ID: {0}; Name: {1}", result.ProductID, result.Name)
Next
