JSON到数组C＃

Question

I Have a JSON with this values

{"interface":"ALL",
 "dv":"1",
 "alarms":[{"Id":0,
            "Type":"URL",
            "Trigger":"facebook",
            "Output":"video"},
           {"Id":1,
            "Type":"URL",
            "Trigger":"twitter",
            "Output":"video"},
           {"Id":2,
            "Type":"URL",
            "Trigger":"ebay",
            "Output":"video"}
]}

And i would like parse this information to mi C# Code

I do this for Strings tags and works ok

JObject obj = JObject.Parse(json);
String value =(String) obj["dv"]; 

but i have an error for tag Array alarms. I've tried with:

Array value = null;
value =(Array) obj["alarm"]; 

but i get an error (Message=Can not convert Array to byte array. Source=Newtonsoft.Json).

Answer 1

Try convert your alarms into a JArray :

JArray value = null;
value = obj["alarms"] as JArray;

Answer 2

You could use JavaScriptSerializer for this.
For example:

JavaScriptSerializer jss = new JavaScriptSerializer();
Dictionary<string, object> dict = jss.Deserialize<Dictionary<string, object>>(jsonString);

Answer 3

Using Json.Net

JArray value = null;
value = obj["alarms"] as JArray;

The casting should be JArray

Answer 4

Your json string has a reserved c# keyword: interface . Try changing this and see if it works.
