มีปัญหาดึงข้อมูลจากคลาส IQueryable <> ออกมาไม่เป็นครับ Project WPF,C#.NET,LINQ to SQL

        Database.dbLaunderDataContext db = new Database.dbLaunderDataContext();
        IQueryable<Database.Member> IMember;


	void txtSearch_KeyDown(object sender, KeyEventArgs e)
        {

            tileWrapPanel.Margin = new Thickness(0, 0, 20, 0);
            // 3 tiles height-wise
            tileWrapPanel.Height = (110 * 3) + (6 * 3);
            if (txtSearch.Text == string.Empty)
            {
                MetroStackPanel.Children.Clear();
                return;

                          where i.MID.Contains(txtSearch.Text.Trim()) || i.MemberName.Contains(txtSearch.Text.Trim())
                          orderby i.MemberName
                          select i;
                if (IMember.Count() > 0)
                {
                    foreach (var s in IMember.ToList())
                    {
                        GiriyaLaundry.Resources.Tile newTail = new Tile();
