LINQ 中实现自动表对象装填

设计背景：因做项目使用到了linq，但考虑对表单进行操作时比较麻烦，所以想了一个办法，利用反射自动装填表对象实现更新、插入！
工作原理：首先遍历出需要的容器控件，然后将控件内容装填到hash表，然后 通过hash表填充表对象

/// <summary>
        /// 遍历control找到需要的controls
        /// </summary>
        /// <param name="parent"></param>
        /// <param name="ctlForm"></param>
        /// <param name="sTarCtlId"></param>
        static public void GetConTrolById(Control parent, ref Control ctlForm, string sTarCtlId)
        {
            if (parent == null) return;
            foreach (Control c in parent.Controls)
            {
                if (CFunc.ToString(c.ID) == sTarCtlId)
                {
                    ctlForm = c;
                    return;
                }                
                if (c.Controls.Count > 0) GetConTrolById(c, ref ctlForm, sTarCtlId);
            }
        }
        /// <summary>
        /// 从表单中获取控件填充至hash
        /// </summary>
        /// <param name="control"></param>
        /// <returns></returns>
        static public Hashtable CTGetHash(Control control)
        {
            try
            {
                Hashtable hash = new Hashtable();
                foreach (Control c in control.Controls)
                {
                    string cType = c.GetType().Name.ToLower();
                    string cName =CFunc.ToString(c.ID);
                    if (cName.IndexOf("Hide") > 0)
                        continue;
                    switch (cType)
                    {
                        case "Label":
                            break;
                        case "UltraLabel":
                            break;
                        case "Button":
                            break;
                        case "webdatechooser":
                            hash[((WebDateChooser)c).ID] = ((WebDateChooser)c).Value;
                            break;
                        case "webnumericedit":

                            break;
                        case "dropdownlist":
                            hash[((DropDownList)c).ID] = ((DropDownList)c).SelectedValue;
                            break;
                        case "hiddenfield":
                            hash[((HiddenField)c).ID] = ((HiddenField)c).Value;
                            break;
                        case "checkbox":
                            if (((CheckBox)c).Checked)
                                hash[((CheckBox)c).ID] = 1;
                            else
                                hash[((CheckBox)c).ID] = 0;
                            break;
