javascript : pass an array to WCF service (c#)

Question

I am trying to send an array to a wcf service.

My javascript :

var listoffice = new Array();

var office1 = { officeid : "1", officename : "Bat Cave" };
var office2 = { officeid : "2", officename : "Robin House" };

listoffice[0] = office1;
listoffice[1] = office2;

$.getJSON("ContactService.svc/createnewAwesomeoffice", { listoffice: listoffice }, function (data) {
   ...           
});

Here's the service :

public struct officetoadd
{
     public string officeid;
     public string officename;
}

[OperationContract]
[WebGet(ResponseFormat = WebMessageFormat.Json)]
public void createnewAwesomeoffice(List<officetoadd> listoffice)
{
   ...
}

the problem is the listoffice(in the service) is always null. Am I missing something ?

I think you need to put RequestFormat as well in your WebGetAttribute... Also, you may want to try turning "officetoadd" into a class and decorate it with DataContract and DataMember Attributes.

[DataContract]
public class officetoadd
{
     [DataMember]
     public string officeid;
     [DataMember]
     public string officename;
}

[OperationContract]
[WebGet(RequestFormat - WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
public void createnewAwesomeoffice(List<officetoadd> listoffice)
{
   ...
}

Ty a lot for your suggestion, but I simply use JSON.stringify.

Can I set the parameter as IEnumerable<T> or any other interface or a class that is more primitive than List<T>?

Ok, I found a solution by myself. I think this is pertinent to write it here, so it may help other people.

I simply had to convert my array to JSON with this :

var arrayjson = JSON.stringify(listoffice);

And then pass it to the WCF service :

$.getJSON("ContactService.svc/createnewAwesomeoffice", { listoffice: arrayjson }, function (data) {
   ...           
});

Note: The JSON object is now part of most modern web browsers (IE 8 & above).
