源返回json：

{
  "Result": {
    "AccName": "New 2018-05-08 11:22:44",
    "BeginTime": "1970-01-01T00:00:00",
    "EndTime": null,
    "MaxDrawDownRate": 0.0,
    "AccountCorporation": "",
    "YearProfitPrecentage": 0.0,
    "CreateUserName": "MatrixUser",
    "HasDataType": "期货,股票",
    "DataTypes": [
      {
        "Value": "8",
        "Text": "期货",
        "Name": null
      },
      {
        "Value": "1",
        "Text": "股票",
        "Name": null
      }
    ],
    "SumAmount": 2000000.0,
    "CapitaleAmount": 2000000.0,
    "Cash": 0.0
  },
  "Head": {
    "Message": "获取成功",
    "Code": "200",
    "CallTime": "2018-05-24 15:19:04"
  }
}

现在前端不需要DataTypes这个节点数据，需要在后台移除掉，将此json作为变量json传入方法JObject.Parse(json)
处理代码：

//移除某个属性，以不返回该数据
JObject jobject = JObject.Parse(json);           
JObject tokenselect = jobject.SelectToken("Result") as JObject;
tokenselect.Remove("DataTypes");

完整的代码

using Newtonsoft.Json.Linq;

public ActionResult Detail(int id)
    //待处理的josn字符串
	string json="";
    //移除某个属性，以不返回该数据
    JObject jobject = JObject.Parse(json);           
    JObject tokenselect = jobject.SelectToken("Result") as JObject;
    tokenselect.Remove("DataTypes");
    return Json(tokenselect);
}

var skuListJson=[{"ProductCategorySysNo":"467011276116070400","MalfunctionsSysNo":"467011100731248640","PropertyValueSysNos":"467011331313111040,467011331510243328,467011332495904768","SysNo":"467011332256829440","Price":2500.00},{"ProductCategorySysNo":"467011276116070400","MalfunctionsSysNo":"467011100731248640","PropertyValueSysNos":"467011331313111040,467011331510243328,467011331845787648","SysNo":"467011331208253440","Price":2000.00},{"ProductCategorySysNo":"467011276116070400","MalfunctionsSysNo":"467011095232516096","PropertyValueSysNos":"467011326095396864,467011326493855744,467011330340032512","SysNo":"467011330189037568","Price":0.00}];	
	
Newtonsoft.Json.Linq移除對象中不需要的屬性或字段
JArray對應的是集合，JObject對應一條記錄
//list是一個C#List<T>對象泛型集合
JArray jArray = JArray.FromObject(list);
//方式二：這樣也行
//JArray jArray =JArray.Parse(skuListJson);
foreach (JObject item in jArray)
{              
    //移除屬性SysNo、ProductCategorySysNo
	item.Remove("SysNo");
	item.Remove("ProductCategorySysNo");
}         
//最後在將jArray序列化為json字符串
string skuListJson = JsonConvert.SerializeObject(jArray);
