C# ASP.NET mvc中的存储过程错误

我试图在我的MVC应用程序中使用一个存储过程，但是我一直遇到这个错误：数据读取器与指定的'GiftworxModel.Card'不兼容。“CardID”类型的成员在数据读取器中没有同名的对应列。任何协助都将不胜感激

我的存储过程

GO

ALTER PROCEDURE  [dbo].[GetBalance]
-- Add the parameters for the stored procedure here
@CardNumber nvarchar(20)

AS
BEGIN

SET NOCOUNT ON;
If Not Exists(Select CardID From Cards With (NOLOCK) Where CardNumber = @CardNumber OR (Cards.CardNumber2 = @CardNumber))
Begin
Select 'Invalid Card Number' as Error
END

END

我的上下文类：

public virtual ObjectResult<string> GetBalance(string cardNumber)
{
    var cardNumberParameter = cardNumber != null ?
        new ObjectParameter("CardNumber", cardNumber) :
        new ObjectParameter("CardNumber", typeof(string));

    return ((IObjectContextAdapter)this).ObjectContext.ExecuteFunction<string>("GetBalance", cardNumberParameter);
}

您可以共享视图代码吗？您没有在查询中选择CardID，这正是错误告诉您的。你的问题是什么？它使用哪种select语句。对不起，伙计，我对存储过程和在asp.NET中访问它们还很陌生。在您的存储过程映射中，您是否已将其映射到Card类？那么为什么该方法返回字符串集合呢。你能告诉我们哪行代码出错吗？您是否能够在sql management studio中运行该过程并毫无问题地获得结果？

[HttpPost]
public ActionResult GetBalance(string cardNumber)
{

    var balance = db.GetBalance(cardNumber).ToList();

    return View("GetBalance");

}
