Examples
This example adds new parameters to the collection and gets the count of the parameters in the collection. Then it iterates through the ObjectParameterCollection and displays the name, type, and value of each parameter in the collection.
using (AdventureWorksEntities context =
new AdventureWorksEntities())
{
string queryString =
@"SELECT VALUE contact FROM AdventureWorksEntities.Contacts
AS contact WHERE contact.LastName = @ln AND contact.FirstName = @fn";
ObjectQuery<Contact> contactQuery =
new ObjectQuery<Contact>(queryString, context);
// Add parameters to the collection.
contactQuery.Parameters.Add(new ObjectParameter("ln", "Adams"));
contactQuery.Parameters.Add(new ObjectParameter("fn", "Frances"));
ObjectParameterCollection objectParameterCollection =
contactQuery.Parameters;
Console.WriteLine("Count is {0}.", objectParameterCollection.Count);
// Iterate through the ObjectParameterCollection collection.
foreach (ObjectParameter result in objectParameterCollection)
{
Console.WriteLine("{0} {1} {2}", result.Name,
result.Value,
result.ParameterType);
}
}
