You should look at using the JavaScriptSerializer. It's part of the .NET framework (distributed in System.Web.Extensions). To get the result you want you can do this:

var results = new[]
{
    new{id=1,name="Result 1"},
    new{id=2,name="Result 2"},
    new{id=3,name="Result 3"}
};

var js = new JavaScriptSerializer();
var result = js.Serialize(new
{
    status = "ok",
    response = results,
    caller = 1135345
});

You can either use anonymous classes, or any existing ones. Works perfectly fine :) The return value of this call would be:

{"status":"ok","response":[{"id":1,"name":"Result 1"},{"id":2,"name":"Result 2"},{"id":3,"name":"Result 3"}],"caller":1135345}
