我利用xml-rpc.net进行网络的下载返回xml，形式如下：

在调试时发现它利用的ParseFault函数解析的

这是我接受的代码

private void AddPer(string name)
{
DeletedGuidHelper.DeletedGuidRequest dg = new DeletedGuidHelper.DeletedGuidRequest();
dg.api_version = "4";
dg.client_type = "WP7";
dg.count = 200;
UserHelper users = new UserHelper();
Users u = users.GetUser(name);
dg.kb_guid = u.Kb_guid;
dg.program_type = "normal";
dg.token = u.Token;
MetaHelper mh = new MetaHelper();
WizMeta wm = mh.GetWizMeta("SYNC_VERSION", "DELETED_GUID");
if (wm.Meta_Value == null)
{
mh.InsertMeta("SYNC_VERSION", "DELETED_GUID", "0");
dg.version = "0";
}
else
{
dg.version = wm.Meta_Value;
}

password = u.Kapi_url;
SendXml(dg);
DeletedGuidHelper dgh = new DeletedGuidHelper();

var proxy = new StateNameProxy();
object ll1 = null;
proxy.BeginGetWizDeletedGuid(new object[] { dg }, asr =>
{
Dispatcher.BeginInvoke(delegate()
{
try
{
ll1 = proxy.EndGetWizDeletedGuid(asr);
}
catch (XmlRpcFaultException fex)
{
}
catch (Exception ex)
{
}
});
});
ll = (List<DeletedGuidHelper.KObjectDeleted>)ll1;
//textBlock1.Text = ll.Count.ToString();

}

调试的时候发现ll1是null

我的登录是可以的请各位高手们个看看
