代碼：

//這樣寫的話，輸入的是表的行對象，返回的是數據字典，可以直接用到更新操作里，public static Object AlterDate(Object tabledataobj){List<string> namelist = new List<string>();List<Object> valuelist = new List<object>();Type t = tabledataobj.GetType();foreach (PropertyInfo pi in t.GetProperties()){if (pi.Name == "id"){ }else{Object value = pi.GetValue(tabledataobj);if (value != null){namelist.Add(pi.Name);valuelist.Add(value);}}}Dictionary<string, object> temp = new Dictionary<string, object>();for (int i = 0; i < namelist.Count; i++){temp.Add(namelist[i], valuelist[i]);}temp.Add("updateTime", DateTime.Now);return temp;}//用到更新操作里，參考如下：var dic = new Dictionary<string, string>();dic.Add("name", "第十三條");dic.Add("areaId", "1");db.Update<School, int>(dic, 13);或：Object obj = AlterTable.AlterDate(dt);……var result = db.Update<t_customer,int>(obj,cusid);//方法重載，只有第二個參數里包含的字段才能進行修改public static Object AlterDate(Object tabledataobj,List<string> modifiableField){List<string> namelist = new List<string>();List<Object> valuelist = new List<object>();Type t = tabledataobj.GetType();foreach (PropertyInfo pi in t.GetProperties()){if (pi.Name == "id"){ }else{if (modifiableField.Contains(pi.Name)){Object value = pi.GetValue(tabledataobj);if (value != null){namelist.Add(pi.Name);valuelist.Add(value);}}}}Dictionary<string, object> temp = new Dictionary<string, object>();for (int i = 0; i < namelist.Count; i++){temp.Add(namelist[i], valuelist[i]);}temp.Add("updateTime", DateTime.Now);return temp;}//這樣寫的話，后面表示的是動態的的生成對象，并且動態的給對象添加屬性public static Object AlterDate(Object tabledataobj){List<string> namelist = new List<string>();List<Object> valuelist = new List<object>();Type t = tabledataobj.GetType();foreach (PropertyInfo pi in t.GetProperties()){if (pi.Name == "id"){ }else{Object value = pi.GetValue(tabledataobj);if (value != null){namelist.Add(pi.Name);valuelist.Add(value);}}}Dictionary<string, object> temp = new Dictionary<string, object>();for (int i = 0; i < namelist.Count; i++){temp.Add(namelist[i], valuelist[i]);}temp.Add("updateTime", DateTime.Now);dynamic result = new System.Dynamic.ExpandoObject();foreach (KeyValuePair<string, object> item in temp){((IDictionary<string, object>)result).Add(item.Key, item.Value);}return result;}

// 另一種方式
ExpandoObject 類，“需引用System.Dynamic命名空間”?

? ? ? ? ? ??dynamic?person =?new?ExpandoObject();

????????????person.Name =?"cary";

????????????person.Age =?25;

????????????person.ShowDescription =?new?Func<string>(() => person.Name + person.Age);

?

????????????Console.WriteLine(person.Name+person.Age+person.ShowDescription()); ? ? ? ? ??

????????????Console.ReadLine();
