SharePoint的文档库非常方便,可以管理日常的文档,更强大的是可以创建文件夹来分类,通常在UI界面上是非常简单了,点击文件夹,Create a Folder即可。但是,怎样手动去创建文件夹呢,怎样在文件夹中创建子文件夹。
项目分析
- 举个栗子,我需要上传文档到文档库,希望把该文件上传到以年、月、日、上传人命名的子文件夹中,如:2013年-->5月-->11日-->陈小春,如下图所示这样
- 点击2013年,进入当前月子文件夹
- 点击当前月,进入以上传人命名的子文件夹
- 点击上传人(陈小春),即可看到我们上传的文档
代码实现
- 首先我们完成对参数的设置,初始化参数
//获取年度参数 string folderYearParameter = DateTime.Now.Year.ToString() + "年"; //获取月度参数 string folderMonthParameter = DateTime.Now.Month.ToString() + "月"; //获取当前登录用户名: string currentLoginName = SPContext.Current.Web.CurrentUser.LoginName; currentLoginName = currentLoginName.Substring(currentLoginName.LastIndexOf("\\") + 1); string currentUserDisplayName; //获得Display name //当Administrator上传有问题 ?因为 当administrator登陆时 DisplayName=Wllgwh\administrator,invalid Path SPUser spUser = SPContext.Current.Web.AllUsers[SPContext.Current.Web.CurrentUser.LoginName]; currentUserDisplayName = spUser.Name; if (currentUserDisplayName.Contains("\\")) { currentUserDisplayName = currentUserDisplayName.Substring(currentUserDisplayName.LastIndexOf("\\")+1); }
- 提权
创建文件夹之前,判断是否存在该文件夹,若不存在,则创建之。之后创建Byte数组,将上传的文档附加到SubFolder中。
SPSecurity.RunWithElevatedPrivileges(delegate() { var homeUrl = SPContext.Current.Site.Url; SPSite site = new SPSite(homeUrl + "/jxkp"); SPWeb web = site.OpenWeb(); //获取List SPList list = web.Lists.TryGetList("绩效考评"); SPFolder folderYear = list.ParentWeb.GetFolder(list.RootFolder.ServerRelativeUrl + "/" + folderYearParameter); if (!folderYear.Exists) { SPListItem folder = list.Items.Add(list.RootFolder.ServerRelativeUrl, SPFileSystemObjectType.Folder, folderYearParameter); web.AllowUnsafeUpdates = true; folder.Update(); web.AllowUnsafeUpdates = false; } //判断folderMonth是否存在,不存在则创建 SPFolder folderMon = list.ParentWeb.GetFolder(list.RootFolder.ServerRelativeUrl + "/" + folderYearParameter + "/" + folderMonthParameter); if (!folderMon.Exists) { //创建子文件夹 SPListItem subFolder = list.AddItem(list.RootFolder.ServerRelativeUrl, SPFileSystemObjectType.Folder, folderYearParameter + "/" + folderMonthParameter); web.AllowUnsafeUpdates = true; subFolder.Update(); web.AllowUnsafeUpdates = false; } //判断CurrentlyUser是否存在,不存在则创建,这么长的一串,之后重构 SPFolder folderCurrUser = list.ParentWeb.GetFolder(list.RootFolder.ServerRelativeUrl + "/" + folderYearParameter + "/" + folderMonthParameter + "/" + currentUserDisplayName); if (!folderCurrUser.Exists) { SPListItem userFolder = list.AddItem(list.RootFolder.ServerRelativeUrl, SPFileSystemObjectType.Folder, folderYearParameter + "/" + folderMonthParameter + "/" + currentUserDisplayName); web.AllowUnsafeUpdates = true; userFolder.Update(); web.AllowUnsafeUpdates = false; } if (fileUploadJxkp.PostedFile != null) { if (fileUploadJxkp.PostedFile.ContentLength > 0) { System.IO.Stream stream = fileUploadJxkp.PostedFile.InputStream; byte[] bytFile = new byte[Convert.ToInt32(fileUploadJxkp.PostedFile.ContentLength)]; stream.Read(bytFile, 0, Convert.ToInt32(fileUploadJxkp.PostedFile.ContentLength)); stream.Close(); SPFolder subSPFolder = list.ParentWeb.GetFolder(list.RootFolder.ServerRelativeUrl + "/" + folderYearParameter + "/" + folderMonthParameter + "/" + currentUserDisplayName); web.AllowUnsafeUpdates = true; subSPFolder.Files.Add(System.IO.Path.GetFileName(fileUploadJxkp.PostedFile.FileName), bytFile, true); web.AllowUnsafeUpdates = false; // labMsg.Text = "绩效考评已上传成功"; string successScript = string.Format("$.jnotify('{0}');", "上传成功"); ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "smManager", successScript, true); } } });
小结
SharePoint的文档库归根到底还是List,学习SharePoint是条漫长的路,吾将上下而求索,有距,无惧。
