Converting to correctly formatted JSON - json

Question

I've been tasked will calling an API, that needs to take a JSON payload as its request.. An example format of the JSON is as follows:
{
"method":"methodname",
"in":[
{
"account":"acme",
"context":"abc123"
},
"content",
{
"mSearchText":"chocolate",
"mItemDataIDs":[
"Entry:ID",
"Entry:EntryRef",
"Entry:CategoryID"
]
}
]
}
I am using JSON.NET (Newstonsoft) to construct my JSON from .net objects.
The issue I am facing is correctly constructing the "in" section..
It appears to be an array of objects, but only the second item has a title ("content",{.....})..
The closest I can get is:
{
"method": "methodname",
"in":[
{
"account": "PANDO",
"context": "sdfsd22342"
},
{
"mSearchText":"chocolate",
"mItemDataIDs":[
"Entry:ID",
"Entry:EntryRef",
"Entry:CategoryID"
]
}
]
}
Which is identical apart from "content", is missing:
My code so far is:
public class Payload
{
public string method { get; set; }
[JsonProperty("in")]
public List<object> Items { get; set; }
}
public class AccountDetails
{
public string account { get; set; }
public string context { get; set; }
}
[JsonObject(Title = "content")]
public class Content
{
public string mSearchText { get; set; }
public string[] mItemDataIDs { get; set; }
}
Payload payload = new Payload();
payload.method = "methodname";
payload.Items = new List<object>();
payload.Items.Add(new AccountDetails
{
account = "acme",
context = "abc123"
});
Content conent = new Content
{
mSearchText = "chocolate",
mItemDataIDs = new string[] { "Entry:ID", "Entry:EntryRef", "Entry:CategoryID" }
};
payload.Items.Add(conent);
string jsonObject = JsonConvert.SerializeObject(payload, Formatting.Indented);
Any suggestions on what I can do?
