How to correctly format JSON responses (for jQuery) from ASP.NET AJAX?
<p>Guys, I can't seem to get the object serialization working correctly clientside for my app? When I used the getJSON() method inside jQuery with a response mime type of text/json (serialized using JSON.Net library), it was working fine, but as soon as I moved it across to an ajax() request (so I could post my code in webmethods on my page) its fallen apart. Any ideas would be greatly appreciated.</p>

<p>Edit: I'm using framework 2.0, not 3.5</p>

<p>My javascript looks like this:</p>

<pre><code> function companySearch(txt) 
 {
     $("#&lt;%= divCompanyResult.ClientID %&gt;").hide();
        $("#&lt;%= divCompanyResult.ClientID %&gt;").html("");

        var strCompanySearch = $("#&lt;%= tbCompanySearch.ClientID %&gt;").val();

        $.ajax
        ({
            type: "POST",
            url: "Home.aspx/GetCompanies", 
            contentType: "application/json; charset=utf-8", 
            datatype: "json",
            data: "{name: '" + strCompanySearch + "'} ", 
            success: companySearchSuccess,
            error: onError
        });

        return (true);
 }

 function companySearchSuccess(response)
 {
        $.each(response, 
            function(i, company) 
            {
                $("#&lt;%= divCompanyResult.ClientID %&gt;").prepend(company.Name + "&lt;br /&gt;");
            });

        $("#&lt;%= divCompanyResult.ClientID %&gt;").slideDown(1000);
 }
</code></pre>

<p>And my .ASPX page (nb. its a page, not a webservice), looks like this:</p>

<pre><code>    [WebMethod]
    public static Company[] GetCompanies(string name)
    {
        Company[] companies = Company.FindCompanies(name);

        return companies;
    }
</code></pre>

<p>And the object its returning:</p>

<pre><code>[ActiveRecord]
