Create Json dynamically in c#
[TestFixture]
public class DynamicJson
{
[Test]
public void Test()
{
dynamic flexible = new ExpandoObject();
flexible.Int = 3;
flexible.String = "hi";
var dictionary = (IDictionary<string, object>)flexible;
dictionary.Add("Bool", false);
var serialized = JsonConvert.SerializeObject(dictionary); // {"Int":3,"String":"hi","Bool":false}
}
}
I found a solution very similar to DPeden, though there is no need to use the IDictionary, you can pass directly from an ExpandoObject
to a JSON convert:
dynamic foo = new ExpandoObject();
foo.Bar = "something";
foo.Test = true;
string json = Newtonsoft.Json.JsonConvert.SerializeObject(foo);
and the output becomes:
{ "FirstName":"John", "LastName":"Doe", "Active":true }
You should use the JavaScriptSerializer
. That can Serialize actual types for you into JSON :)

EDIT: Something like this?
var columns = new Dictionary<string, string>
{
{ "FirstName", "Mathew"},
{ "Surname", "Thompson"},
{ "Gender", "Male"},
{ "SerializeMe", "GoOnThen"}
};
var jsSerializer = new JavaScriptSerializer();
var serialized = jsSerializer.Serialize(columns);
Output:
{"FirstName":"Mathew","Surname":"Thompson","Gender":"Male","SerializeMe":"GoOnThen"}
