Deserialising json C# (1 answer)

Closed 2 years ago.

I have code that returns json data from a post api call. The data is in the below format:

{"data":[{"name":"123","pwd":123},{"name":"456","pwd":456},{"name":"789","pwd":789}]",duration":5309,"query":"myquery","timeout":300}

To deserialise the above json, I have written the following code:

Product myprod = JsonConvert.DeserializeObject<Product>(result);
var results = myprod.result;

My data remains null with count=0. Could anyone help me with where am I going wrong ?

回答1:

First your json is invalid. Here is the same one but with fixes.

{"data":[{"name":"123","pwd":123},{"name":"456","pwd":456},{"name":"789","pwd":789}],"duration":5309,"query":"myquery","timeout":300}

And with this json model should look like this:

public class Rootobject
{
    public Datum[] data { get; set; }
    public int duration { get; set; }
    public string query { get; set; }
    public int timeout { get; set; }
}

public class Datum
{
    public string name { get; set; }
    public int pwd { get; set; }
}

DeserializeObject can not convert data struct to IList<IList<string>> . You should implement custom JsonConverter yourself.
