sharepoint的问题

[canyangruxie]

sharepoint，通过client对象模型改变Web.AllProperties属性值后，通过server对象模型SPWeb.Properties访问不到。这是为什么？

using (ClientContext clientContext = new ClientContext(SharePointSiteUrl))
                {
                    clientContext.AuthenticationMode = ClientAuthenticationMode.FormsAuthentication;
                    clientContext.FormsAuthenticationLoginInfo = new FormsAuthenticationLoginInfo(SharePointSiteUser, SharePointSiteUserPassword);
                    Web oWebsite = clientContext.Web;
                    clientContext.Load(oWebsite.AllProperties);

                    try
                    {
                        clientContext.ExecuteQuery();

                        oWebsite.AllProperties[key] = value;

                        oWebsite.Update();

                        clientContext.ExecuteQuery();
                    }
                    catch (Exception ex)
                    {
                        MessageBox.Show(ex.Message);
                    }
                }
