Create nested json with c#

Question

I am able to create a flat serialized JSON string pretty easily with c#

My issue is I want to create a nested string like this below

You can make use of the ExpandoObject under the System.Dynamic namespace.

Here is a small snippet for achieving your solution:

dynamic parameters = new dynamic[2];

parameters[0] = new ExpandoObject();
parameters[0].title = "Yes";
parameters[0].id = "1";

parameters[0].menu = new dynamic[1];
parameters[0].menu[0] = new ExpandoObject();

parameters[0].menu[0].title = "Maybe";
parameters[0].menu[0].id = "3";
parameters[0].menu[0].alert = "No";
parameters[0].menu[0].menu = new dynamic[1];
parameters[0].menu[0].menu[0] = new ExpandoObject();
parameters[0].menu[0].menu[0].title = "Maybe Not";
parameters[0].menu[0].menu[0].id = "8";
parameters[0].menu[0].menu[0].alert = "No";
parameters[0].menu[0].menu[0].menu = new dynamic[0];

parameters[1] = new ExpandoObject();
parameters[1].title = "No";
parameters[1].id = "2";
parameters[1].menu = new dynamic[0];


string json = JsonConvert.SerializeObject(parameters, Formatting.Indented);
Console.WriteLine(json);

Here is the work in fiddle

Note: There are other ways to achieve this, but I have been using this approach.
