How to get average values using stored procedure

Hi

 

This is my web api code like this :

 

[Authorize]
[RoutePrefix("api/Cards")]
public class CardsController : ApiController
{
private Card _card = new Card();
[HttpGet]
[OverrideAuthorization]
[Route("GetCard/{teamId}/metrics/{memberId}")]
public List GetCards(int teamId, int memberId)
{
//Send the list of cards associated with the team. Also send member previous rating and team average rating of past 7 days
return _card.GetCardDetails(teamId, memberId);
}

 

and this is my data access layer code :

 

public List GetCardDetails(int teamid,int memberid)
{
var Getcard = (from c in _DataContext.uspGetCard(teamid, memberid) select new CardData { CardID = c.CardID, CardName = c.CardName, CardDescription = c.CardDescription, VoteValue = c.VoteValue, LastModifiedDateTime = c.LastModifiedDateTime }).ToList();
return Getcard;
} 

 

and this is my CardData Model code like this :

 

public class CardData
{
public int CardID { get; set; }
public string CardName { get; set; }
public string CardDescription { get; set; }
public CardRatingData CardRating { get; set; }
public int VoteValue { get; set; }
public DateTime LastModifiedDateTime { get; set; }
}

 

and this is CardRatingData model code like this :

 

public class CardRatingData
{
public int MemberPreviousRating { get; set; }
public DateTime MemberPreviousRatingDateTime { get; set; }
public double TeamAverage7DayRating { get; set; }
}
