sharepoint 2013 获取文档库文件夹树形结构

在做sharepoint 2013或者sharepoint 2010文档库的过程中，经常会建很多的文件夹，不同类别存储不同文件，相当于文档的分类，这里主要是记录一下，将文档库的文件夹结构，绑定到treeview。

protected  void  Page_Load(object sender,EventArgse)

        {

            if(!Page.IsPostBack)

            {

               BindData();

            }

        }

        private void BindData()

        {

            SPSite site =newSPSite("http://win2012sp/");

            SPWeb spWeb = site.OpenWeb();

            SPList spList = spWeb.Lists["共享文档"];

           tvTreeCatalog.Nodes.Add(CreateNodeByList(spList));

           spWeb.Dispose();

        }

        private TreeNode  CreateNodeByList(SPListspList)

        {

            TreeNode node =newTreeNode();

           node.Text = spList.Title;

           node.Value = spList.RootFolder.Url;

            foreach(SPFolder subFolderin spList.RootFolder.SubFolders)

            {

                if(subFolder.Name !="Forms")

               {

                   node.ChildNodes.Add(CreateNodeByFolder(subFolder));

               }

            }

            return node;

        }

        private TreeNode CreateNodeByFolder(SPFolderspFolder)

        {

            TreeNode node =newTreeNode();

           node.Text = spFolder.Name;

           node.NavigateUrl = SPContext.Current.Web.Lists["共享文档1"].DefaultViewUrl+"?RootFolder="+spFolder.Url;

           node.ImageUrl = SPControl.GetContextWeb(Context).Url+"/_layouts/images/folder.gif";

            foreach(SPFolder subFolderin spFolder.SubFolders)

            {

               node.ChildNodes.Add(CreateNodeByFolder(subFolder));

 

            }

            return node;

        }
