多In/Out參數預存程序的查詢與處理

[OperationContract]
public VoteStatus SetVoteInfo(int? activityObjectID, int? voterMemberID, int? activityID)
{
    ActivityEntities ent = new ActivityEntities();
    ObjectParameter isVoteOp = new ObjectParameter("isvote", typeof(int));
    ObjectParameter billsOp = new ObjectParameter("bills", typeof(int));
    ent.VoteUp(activityObjectID, voterMemberID, activityID, isVoteOp, billsOp);          
    VoteStatus v = new VoteStatus();
    v.IsVote = ((int)isVoteOp.Value == 1) ? true : false;
    v.ObjectBills = (int)billsOp.Value;
    return v;
}

[DataContract]
public class VoteStatus
{
    [DataMember]
    public Boolean IsVote
    { get; set; }
    [DataMember]
    public int ObjectBills
    { get; set; }
}
