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;
             }
         }
