我看不到使用ToList（）; 或在此select语句中使用（6）个项目

Question

I cant seen to use ToList(); or take(6) items on this select statement. I need to select only 6. this is what i have witch works but displays 1 only on the 6 iterations of the repeater.

    public string GetImage(string pId)
    {
        Compras context = new Compras();
        Product pr = context.Products.FirstOrDefault();
        if (pr != null && pr.Picture != null && pr.Picture.Count() > 0)
        {
            return "data:image/jpg;base64," + Convert.ToBase64String((pr.Picture));
        }
        return "data:image/jpg;base64," + Convert.ToBase64String(File.ReadAllBytes(Server.MapPath("~/") + "white.jpg"));
    }

I wish i could use as on this next:

        var context = new Compras();
        var prouctQ = from p in context.Products.Take(6) select new { p.ProductName, p.Picture }; //with projections
        var Products = prouctQ.ToList();
        if (Products.Count > 0)

请确保您在代码文件的顶部具有“ using System.Linq”。
