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=Wllgwhadministrator,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。
代码语言:javascript复制 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。
