Use JSON serialization in .net version >= 3.5. A little example:

[DataContract]
class Student
{
  [DataMember]
  public string Name { get; set; }
  [DataMember]
  public int Age { get; set; }
}

static void Main(string[] args)
{
  var serializer = new DataContractJsonSerializer(typeof (Student));
  var student = new Student {Name = "Jonh", Age = 18};
  var stream = new MemoryStream();
  serializer.WriteObject(stream, student);
  var jsonString = Encoding.Default.GetString(stream.ToArray());

}

You can find DataContractJsonSerializer in System.Runtime.Serialization.dll

You can use DataContractJsonSerializer to achieve this. Define your response

[DataContract]
class Response
{
    [DataMember]
    private string Content { get; set; }
}

Then serialize your html-response into output stream:

Response response = new Response();
response.Content = html.ToString();
DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(Response));
serializer.WriteObject(context.Response.Stream,response);
