将实体转换为Hashtable

1、将实体转换为Hashtable，用于将实体参数处理为hashtable,方便sql参数传递

　　　　　/// <summary>
        /// 将实体转换为Hashtable
        /// </summary>
        /// <typeparam name="T">实体类型</typeparam>
        /// <param name="obj">实体实例</param>
        /// <returns>Hashtable</returns>
        public static Hashtable ConvertEntityToHashtable<T>(T obj)
        {
            Hashtable hst = new Hashtable();
            try
            {
                Type type = obj.GetType();
                foreach (PropertyInfo pi in type.GetProperties())
                {
                    PropertyInfo property = type.GetProperty(pi.Name);
                    hst.Add(pi.Name, property.GetValue(obj, null));
                }
                return hst;
            }
            catch (Exception ex)
            {
                System.Console.Out.WriteLine(ex.Message);
                return null;
            }
        }
