Question

我有一个带有以下格式化Json的文件

{
  "Id": 0,
  "MsgId": 125,
  "ExceptionDetails": "whatever2"
}


{
  "Id": 1,
  "MsgId": 135,
  "ExceptionDetails": "whatever2"
}

这完全是如何在没有布拉克的文件中

我需要解析这个文本文件并获取这些键的值，例如在这个例子中我需要得到0和1

var json = System.IO.File.ReadAllText(@"C:\development\commonArea\test3.txt");

var objects = JArray.Parse(json); // parse as array

foreach (JObject root in objects)
{
    foreach (KeyValuePair<String, JToken> app in root)
    {
        if (app.Key == "Id")
        {
            var appName2 = app.Key;
            Console.WriteLine(I HAVE NO IDEA);
        }
    }

}

由于

Answer 1

var objects = JArray.Parse(json); // parse as array  

foreach (JObject jobject in objects)
{
    Console.WriteLine(jobject.Value<int>("Id"));
}

打印：

您提供了无效的JSON。我修改了它，以便它成为一个有效的JSON数组：

[
    { "Id": 0, "MsgId": 125, "ExceptionDetails": "whatever2" },
    { "Id": 1, "MsgId": 135, "ExceptionDetails": "whatever2" }
]

创建一个匹配的类，然后使用反序列化器。这是使用System.Web.Script.Serialization命名空间。

public class Item
{
    public int Id { get; set; }
    public int MsgId { get; set; }
    public string ExceptionDetails { get; set; }
}

public class RootObject
{
    public List<Item> Items { get; set; }
    public RootObject DeserializeClass()
    {
         JavaScriptSerializer serializer = new JavaScriptSerializer();
         RootObject obj = serializer.Deserialize<RootObject >(JSONSTRING);
         return obj;
     }
}

如何解析和读取Json格式的文本？
