1.站点集中可以使用SPSite.AllWeb，然后遍历所有站点的isRootWeb，根据siteTemplate取得需要的子站点。

 

/// 
        /// Handles the Load event of the Page control.        /// 
        protected void Page_Load(object sender, EventArgs e)        {            var web = SPControl.GetContextWeb(Context);            var subSite = new SPSite(web.Site.ID).AllWebs;            var list = new List
      
       ();            //Foreach sub site            foreach (SPWeb site in subSite)            {                 if (site.IsRootWeb) continue;                if (site.WebTemplate != WebTemplate.PM.ToString()) continue;                try                {                    var content = site.Lists.TryGetList(ProjectOverviewContent.ProjectListName);                    if (content == null || content.Items.Count == 0) continue;                    var link = new ProjectOverviewContent                    {                        //get sitrUrl                        SubSiteUrl = site.Url,                        //get site created time                        SiteCreateTime = site.Created,                    };                    //Foreach sub site list => ProjectContent                    foreach (SPListItem item in content.Items)                    {                        link.ProjectName = item[ProjectOverviewContent.ProjectNameMapping].TryToString();                        link.StartDate = item[ProjectOverviewContent.StartDateMapping].TryToString().SplitDate();                        link.EndDate = item[ProjectOverviewContent.EndDateMapping].TryToString().SplitDate();                        link.ServiceLine = item[ProjectOverviewContent.ServiceLineMapping].TryToString();                        link.Industry = item[ProjectOverviewContent.IndustryMapping].TryToString();                    }                    content = site.Lists.TryGetList(ProjectOverviewContent.MemberListName);                    if (content == null)                    {                        list.Add(link);                        continue;                    }                    //Foreach sub site list => MemberContent                    foreach (SPListItem item in content.Items)                    {                        link.Position = item[ProjectOverviewContent.PositionMapping].TryToString();                        if (link.Position == Position.MIC.ToString())                        {                            link.MIC = item[ProjectOverviewContent.MemberNameMapping].TryToString();                        }                        else if (link.Position == Position.PIC.ToString())                        {                            link.PIC = item[ProjectOverviewContent.MemberNameMapping].TryToString();                        }                        else if (link.Position == Position.PM.ToString())                        {                            link.PM = item[ProjectOverviewContent.MemberNameMapping].TryToString();                        }                    }                    list.Add(link);                }                catch (SPException spException)                {                    LogHelper.Error(spException);                }                catch (Exception ex)                {                    LogHelper.ShowError(lblErrorMessage, ex);                }            }            list.Sort();            tblProjectOverview.DataSource = list.Take(10);            tblProjectOverview.DataBind();        }
      

 

2.子站点读取站点集数据可以通过New SPSite("url").RootWeb获取。

 

public SPWeb RootSite = new SPSite(ProjectContent.SiteUrlMapping).RootWeb;/// 
        /// Gets the project information from root site.        /// 
        public List
      
        GetProjectInfo(string projectCode)        {            var siteContent = RootSite.Lists[ServiceOfferingContent.ListName];            if (siteContent == null || siteContent.Items.Count == 0) return null;            var list = new List
       
        ();            foreach (SPListItem item in siteContent.Items)            {                var link = new ServiceOfferingContent()                {                    ProjectCode = item[ServiceOfferingContent.ProjectCodeMapping].TryToString(),                    ServiceLine = item[ServiceOfferingContent.ServiceLineMapping].TryToString(),                    Industry = item[ServiceOfferingContent.IndustryMapping].TryToString(),                    Id = item[ServiceOfferingContent.IdMapping].TryToString(),                    Title = item[ServiceOfferingContent.TitleMapping].TryToString(),                    Contents = item[ServiceOfferingContent.ContentsMapping].TryToString(),                    ThumbnailUrl = item[ServiceOfferingContent.ThumbnailUrlMapping].TryToString(),                    HeadImageUrl = item[ServiceOfferingContent.HeadImageUrlMapping].TryToString(),                    ContentsImageUrl = item[ServiceOfferingContent.ContentsImageUrlMapping].TryToString(),                    Summary = item[ServiceOfferingContent.SummaryMapping].TryToString(),                };                if (link.ProjectCode != projectCode) continue;                                list.Add(link);                return list;            }            return null;        }
