C#中如何解析这种json转化成list对象集合，求解

[Mr_fenglebin]

{"Header":{"Flag":true,"Messages":"","PageCount":0,"RowCount":0},"Tbody":[{"BBS_Title":"13种洗发露铅含量检测 全部合格！","Hits":65,"Intime":"\/Date(1375169588573+0800)\/","SFID":30765,"Threadid":4869926,"Username":"v2764104"},{"BBS_Title":"气质联用应用技术培训 8月12日","Hits":47,"Intime":"\/Date(1375163275633+0800)\/","SFID":30760,"Threadid":0,"Username":""},{"BBS_Title":"天瑞仪器资产重组大猜想：并购or被并购","Hits":1122,"Intime":"\/Date(1374802201867+0800)\/","SFID":30701,"Threadid":4870344,"Username":""},{"BBS_Title":"爱丁堡仪器今夏来袭，诚征论文赢手机","Hits":207,"Intime":"\/Date(1374800978947+0800)\/","SFID":30700,"Threadid":0,"Username":""},{"BBS_Title":"喜讯：2013上半年优秀会员评选结果揭晓","Hits":826,"Intime":"\/Date(1374638092677+0800)\/","SFID":30669,"Threadid":4868003,"Username":""},{"BBS_Title":"惊愕：菊花茶尽有名堂——虫子！","Hits":502,"Intime":"\/Date(1374630389867+0800)\/","SFID":30666,"Threadid":4865932,"Username":"unht"},{"BBS_Title":"家用自来水Pb含量验证，你家的呢？","Hits":378,"Intime":"\/Date(1374572221150+0800)\/","SFID":30654,"Threadid":4866772,"Username":"denx5201314"},{"BBS_Title":"两种方法测定水中砷含量的经验探讨","Hits":460,"Intime":"\/Date(1374221687573+0800)\/","SFID":30597,"Threadid":4858951,"Username":"ning-meng"},{"BBS_Title":"《XRF傻瓜书》","Hits":109,"Intime":"\/Date(1374220709343+0800)\/","SFID":30596,"Threadid":4848862,"Username":"yue_qiu"},{"BBS_Title":"东北大米 vs 南方大米 镉含量PK！","Hits":881,"Intime":"\/Date(1374219637390+0800)\/","SFID":30595,"Threadid":4857844,"Username":"yiyuxiner"}]}

我想使用DataContractJsonSerializer来实现序列化成集合。我这里不知道哪里写错了。出来的长度是零

            return (T)serializer.ReadObject(ms);
        }

}

还是我来告诉你们吧。。。这样一下就解析出来了，
