ObjectParameterCollection.CopyTo(ObjectParameter[], Int32) 方法

定義

命名空間:

System.Data.Objects

組件:

System.Data.Entity.dll

允許將集合中的參數複製到提供的陣列中，從位於指定索引處的物件開始。

public:
 virtual void CopyTo(cli::array <System::Data::Objects::ObjectParameter ^> ^ array, int index);

public void CopyTo (System.Data.Objects.ObjectParameter[] array, int index);

abstract member CopyTo : System.Data.Objects.ObjectParameter[] * int -> unit
override this.CopyTo : System.Data.Objects.ObjectParameter[] * int -> unit

Public Sub CopyTo (array As ObjectParameter(), index As Integer)

參數

array

ObjectParameter[]

要將參數複製到其中的陣列。

index

Int32

陣列中要開始複製參數的索引。

實作

CopyTo(T[], Int32)

範例

本範例會將參數複製到指定的陣列。

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;
    ObjectParameter[] objectParameterArray =
        new ObjectParameter[objectParameterCollection.Count];

    objectParameterCollection.CopyTo(objectParameterArray, 0);

    // Iterate through the ObjectParameter array.
    for (int i = 0; i < objectParameterArray.Length; i++)
    {
        Console.WriteLine("Name: {0} Type: {1} Value: {2}",
            objectParameterArray[i].Name,
            objectParameterArray[i].ParameterType,
            objectParameterArray[i].Value);
    }
}
