如何从json读取值？

[会织网的蚂蚁]

jsonstring="{"Result":{"ResponseStatus":{"IsSuccess":true,"Errors":[],"SuccessEntitys":[{"Id":100074,"Number":"DD2019080041","DIndex":0}],"SuccessMessages":[],"MsgCode":0},"Id":100074,"Number":"DD2019080041","NeedReturnData":[{}]}}";
如何读取并输出IsSuccess值？

JSON反序列化成实体类

百度:json转实体

我觉得你应该很难写出来写个实体类

编辑 -> 选择性粘贴 -> 将JSON粘贴为类。

{
	"Result": {
		"ResponseStatus": {
			"IsSuccess": true,
			"Errors": [],
			"SuccessEntitys": [{
				"Id": 100074,
				"Number": "DD2019080041",
				"DIndex": 0
			}],
			"SuccessMessages": [],
			"MsgCode": 0
		},
		"Id": 100074,
		"Number": "DD2019080041",
		"NeedReturnData": [{}]
	}
}

using System;

class MyApplication
{
    static void Main()
    {
        string jsonString = "{\"Result\":{\"ResponseStatus\":{\"IsSuccess\":true,\"Errors\":[],\"SuccessEntitys\":[{\"Id\":100074,\"Number\":\"DD2019080041\",\"DIndex\":0}],\"SuccessMessages\":[],\"MsgCode\":0},\"Id\":100074,\"Number\":\"DD2019080041\",\"NeedReturnData\":[{}]}}";
        dynamic obj = Newtonsoft.Json.JsonConvert.DeserializeObject<dynamic>(jsonString);
        bool isSuccess = obj.Result.ResponseStatus.IsSuccess;
    }
}

引用 Newtonsoft的json库，可以把json反序列化成动态对象。

[赤珠空想]

Newtonsoft 正解

引用 7 楼 XBodhi. 的回复:

{
	"Result": {
		"ResponseStatus": {
			"IsSuccess": true,
			"Errors": [],
			"SuccessEntitys": [{
				"Id": 100074,
				"Number": "DD2019080041",
				"DIndex": 0
			}],
			"SuccessMessages": [],
			"MsgCode": 0
		},
		"Id": 100074,
		"Number": "DD2019080041",
		"NeedReturnData": [{}]
	}
}

using System;

class MyApplication
{
    static void Main()
    {
        string jsonString = "{\"Result\":{\"ResponseStatus\":{\"IsSuccess\":true,\"Errors\":[],\"SuccessEntitys\":[{\"Id\":100074,\"Number\":\"DD2019080041\",\"DIndex\":0}],\"SuccessMessages\":[],\"MsgCode\":0},\"Id\":100074,\"Number\":\"DD2019080041\",\"NeedReturnData\":[{}]}}";
        dynamic obj = Newtonsoft.Json.JsonConvert.DeserializeObject<dynamic>(jsonString);
        bool isSuccess = obj.Result.ResponseStatus.IsSuccess;
    }
}

不是提供了吗。
