Examples

This example adds new parameters to the collection. 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;

    // Iterate through the ObjectParameterCollection.
    foreach (ObjectParameter result in objectParameterCollection)
    {
        Console.WriteLine("{0} {1} {2}", result.Name,
            result.Value,
            result.ParameterType);
    }
}

Remarks

The parameter type can only be set through a constructor.
