json对象序列化疑问

在System.Web.Extensions 版本1.0.61025.0下，要把datatable和datarow转换成JSON对象，可以采用Microsoft.Web.Preview dll。在web.config可以配置如下：

    <system.web.extensions>
        <scripting>
            <webServices>
                <jsonSerialization maxJsonLength="2000000">
                   <converters>
     <add name="DataSetConverter"   type="Microsoft.Web.Preview.Script.Serialization.Converters.DataSetConverter, Microsoft.Web.Preview, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
              <add name="DataRowConverter" type="Microsoft.Web.Preview.Script.Serialization.Converters.DataRowConverter, Microsoft.Web.Preview, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
             <add name="DataTableConverter" type="Microsoft.Web.Preview.Script.Serialization.Converters.DataTableConverter, Microsoft.Web.Preview, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
             </converters>
             </jsonSerialization>
            </webServices>
            <scriptResourceHandler enableCompression="true" enableCaching="true"/>
        </scripting>
   </system.web.extensions>

在升级System.Web.Extensions 版本到3.5.0.0的dll时候，好像没有对应得Microsoft.Web.Preview dll进行转换。该如何在System.Web.Extensions3.5.0.0版本下进行

DataSet，datarow,datatable 序列化。欢迎大家讨论下，谢谢大家。

.NET技术 ASP.NET Ajax

问题补充： 在.NET3.5框架下，WebService中序列化datatable对象。序列化后的数据中出现多了个“d”属性。{"d":"{\"__type\":\"SFCity.Entities.CBS_Employee, SFCity.Entities, Version=3.2.13.7, Culture=neutral, PublicKeyToken=null\",\"ID\":\"0bf732c7-d8c2-4955-9262-d3c87fad61b1\",\"FEmployeeID\":\"00002\",\"FName\":\"小李\",\"FBranch\":\"AJ\",\"FStation\":\"业务员\",\"FDuty\":\"部门经理\",\"FPlace\":\"福州\",\"FEmail\":\"\",\"FProvince\":\"14:::湖北省\",\"FCity\":\"161:::武汉\",\"FAddress\":\"hhhhhh\"}"}.在.net2.0时，WebService中序列化datatable对象。序列化后的数据为："{\"__type\":\"SFCity.Entities.CBS_Employee, SFCity.Entities, Version=3.2.13.7, Culture=neutral, PublicKeyToken=null\",\"ID\":\"0bf732c7-d8c2-4955-9262-d3c87fad61b1\",\"FEmployeeID\":\"00002\",\"FName\":\"小李\",\"FBranch\":\"AJ\",\"FStation\":\"业务员\",\"FDuty\":\"部门经理\",\"FPlace\":\"福州\",\"FEmail\":\"\",\"FProvince\":\"14:::湖北省\",\"FCity\":\"161:::武汉\",\"FAddress\":\"hhhhhh\"}" 我在web.config配置如下： <system.web.extensions> <scripting> <webServices> <authenticationService enabled="true"></authenticationService>  <jsonSerialization maxJsonLength="2000000"> <converters> <add name="DataTableConverter" type="Ext.Converters.DataTableConverter,Ext"/> </converters> </jsonSerialization> <!-- Uncomment this line to enable the authentication servi
