代码操作Sharepoint文档库（创建、上传附件）

做项目中遇到客户需求，根据Infopath表单生成Excel并上传到Sharepoint指定文档库中

创建文档库

SPSite site = new SPSite(siteurl);
SPListItem item = site.AllWebs["网站名"].Lists["列表名"].Folders.Add("文档库URL", SPFileSystemObjectType.Folder);
item["Name"] = your folder name;
site.RootWeb.AllowUnsafeUpdates = true;
item.Update();
site.RootWeb.AllowUnsafeUpdates = false;

上传文件到指定文档库

FileStream fs = new FileStream(direct, FileMode.Open, FileAccess.Read);
BinaryReader br = new BinaryReader(fs);
Byte[] filecontents = br.ReadBytes((int)fs.Length);
br.Close();
fs.Close();
SPFolder folder = site.RootWeb.GetFolder("文档库url");
string foldername = 上传上去的文档URL;
site.RootWeb.AllowUnsafeUpdates = true;
SPFile sofle = folder.Files.Add(foldername, filecontents, true);
site.RootWeb.AllowUnsafeUpdates = false;
