how to serialize the multi dynamic data in object

I want the response like below JSON formate, how to do.

{"Spans":[

{

"Cant":0.0,

"ContactHeight":5935.0,

"CatenaryHeight":5935.0,

"Stagger":-717.0,

"Kilometerage":26.714,

"TrackName":"1100",

"RouteId":"LEC1",

"StructureName":"G-17-5"

{

"Length":62000.0,

"Versine":0.0,

"Features":null,

"SpanType":"AnchorSpan"

]

}

this is class that I have created

public class SpansItem
{
public int Cant { get; set; }
public int ContactHeight { get; set; }
public int CatenaryHeight { get; set; }
/
public int Stagger { get; set; }
public double Kilometerage { get; set; }
public string TrackName { get; set; }
public string RouteId { get; set; }
public string StructureName { get; set; }
}
public class Root
{
public List Spans { get; set; }
}

Your web api should look like as shown below in order to get the response as you mentioned above

// Root myDeserializedClass = JsonConvert.DeserializeObject(myJsonResponse);
public class Span
{
public double Cant { get; set; }
public double ContactHeight { get; set; }
public double CatenaryHeight { get; set; }
public double Stagger { get; set; }
public double Kilometerage { get; set; }
public string TrackName { get; set; }
public string RouteId { get; set; }
public string StructureName { get; set; }
public double? Length { get; set; }
public double? Versine { get; set; }
public object Features { get; set; }
public string SpanType { get; set; }
}
public class Root
{
public List Spans { get; set; }
}
public HttpResponseMessage GetAll()
{
try
{
Root root= new Root();
using (TestDBContext db = new TestDBContext())
{
var SpanList=db.Spans.ToList();
if(SpanList!=null){
root.Spans=SpanList;
return Request.CreateResponse(HttpStatusCode.OK, root);
}
return Request.CreateErrorResponse(HttpStatusCode.NotFound,"No result found");
}
}
catch{
return new HttpResponseMessage(HttpStatusCode.InternalServerError);
}
}
