Hello,

I am using Visual Studio 2010, Visual C#, .NET framework 4.0.

I have app in IIS. All my methods looks something like this:


        [OperationContract]
        [WebGet(ResponseFormat = WebMessageFormat.Json)]
        public string Select()
        {            
            return "Hello World";
        }

And the work fine - the only problem is how to return DataTable in Json format?

I've found this topic: http://schotime.net/blog/index.php/2008/07/27/dataset-datatable-to-json/

But, nothings comes back from the server. The dictionary<string, object> is created, but nothing is returned from server.

I need to return DataTable in Json format and the (on the client) convert this back to DataTable and show in DataGrid (Windows forms).


Regards, Frenky

Frankly, Frenky, I would use a business object, instead of a DataTable.  You can apply a DataContract to the class, and DataMember to the members, and return a list of those objects.

Yes, very good point. And that list of object I can map to DataTable on the client. I've also found one solution by myself: put DataTable into MemoryStream and return MemoryStream.
