用js取得返回的DataTable类型时，报错：A circular reference was detected while serializing an o

用js取得返回的DataTable类型时，报错：A circular reference was detected while serializing an object of type 'System.Reflection.Module'
创建了一个WebService，返回一个DataTable，代码如下：

C# code

    [WebService(Namespace = "http://tempuri.org/")]    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]    [ToolboxItem(false)]    [ScriptService]    public class Service1 : System.Web.Services.WebService    {        [WebMethod]        public DataTable GetData()        {            DataTable dt = new DataTable("testDT");            dt.Columns.Add(new DataColumn("col1", typeof(int)));            dt.Rows.Add(new object[] { 1 });            return dt;        }    }

前台代码：

JScript code

function btnClick(){    Service1.GetData(HandleStateChange,err);}        function HandleStateChange(result){    alert(result);    assa}function err(result){    alert("Error:" + result._message );}

一点击就报错：A circular reference was detected while serializing an object of type 'System.Reflection.Module'

但是直接进入asmx，调试，没有问题，难道说ASP.Net2.0没有解决DataTable在js上的序列化问题吗？
