我是Newtonsoft的新手,我试图反序列化我的json文件,然后从中查询特定的数据点。这是json的一个例子。
[
{
"reward_type": "1",
"rejected": "0",
"user_id": "538653",
"granted": "0"
},
{
"reward_type": "5",
"rejected": "0",
"user_id": "536345",
"granted": "1"
},
{
"reward_type": "5",
"rejected": "0",
"user_id": "539493",
"granted": "1"
}
]
我试图在每种类型之后查询值。我已经尝试过几天围绕Json.net的文档,但是我很难找到反序列化文件的示例。
以下是我用来解析文件的内容。
InitializeComponent();
JArray adData1 = JArray.Parse(File.ReadAllText(@"c:\ads.json"));
using (StreamReader file = File.OpenText(@"c:\ads.json"))
using (JsonTextReader reader = new JsonTextReader(file))
{
JsonSerializer serializer = new JsonSerializer();
JArray adData2 = (JArray)serializer.Deserialize(file, typeof(JArray));
JObject rewardType = (JObject)adData2[1];
label1.Text = rewardType.ToString();
}
感谢任何帮助。

来自建议:
仅在数据具有共同结构时才可用。如果您愿意,可以替换POCO中的数据类型
POCO
public class Stuff {
public string reward_type { get; set; }
public string rejected { get; set; }
public string user_id { get; set; }
public string granted { get; set; }
}
使用方法:
public void doThings() {
// var s = File.ReadAllText("yourfilename.json");
var s = @"{
""reward_type"": ""1"",
""rejected"": ""0"",
""user_id"": ""538653"",
""granted"": ""0""
},
{
""reward_type"": ""5"",
""rejected"": ""0"",
""user_id"": ""536345"",
""granted"": ""1""
},
{
""reward_type"": ""5"",
""rejected"": ""0"",
""user_id"": ""539493"",
""granted"": ""1""
}";
// [] is needed to make it recognize it as list
var listOfStuff = JsonConvert.DeserializeObject<List<Stuff>>("["+s+"]");
foreach (var item in listOfStuff)
{
Console.WriteLine(item.user_id);
}
}
