ASP.NET MVC3版本
1 //获取编辑数据 这里获取到的是json字符串 2 string deleted = Request.Form["deleted"]; 3 string inserted = Request.Form["inserted"]; 4 string updated = Request.Form["updated"]; 5 6 if(deleted != null){ 7 //把json字符串转换成对象 8 List<Bean> listDeleted = JsonDeserialize<List<Bean>>(deleted); 9 //TODO 下面就可以根据转换后的对象进行相应的操作了 10 } 11 12 if(inserted != null){ 13 //把json字符串转换成对象 14 List<Bean> listInserted = JsonDeserialize<List<Bean>>(inserted); 15 } 16 17 if(updated != null){ 18 //把json字符串转换成对象 19 List<Bean> listUpdated = JsonDeserialize<List<Bean>>(updated); 20 }
JsonDeserialize方法：
private T JsonDeserialize<T>(string jsonString) { DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T)); MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString)); T obj = (T)ser.ReadObject(ms); return obj; }
里面用到的JSON.stringify，主要是把对象转换为字符串的作用。原代码在这里
注意下载这个js后，如果运行出错就去掉最后几行代码。如下删除
1 if (!Object.prototype.toJSONString) { 2 Object.prototype.toJSONString = function (filter) { 3 return JSON.stringify(this, filter); 4 }; 5 Object.prototype.parseJSON = function (filter) { 6 return JSON.parse(this, filter); 7 }; 8 }
