CSOM 转移文档到其它目录

先创建一个项目，然后写一个转移方法

public static void movefiles()

{

try{

　　ClientContent clientContext = new ClientContext(siteUrl);

　　clientContext.RequestTimeout = Timeout.Infinite;

　　var user name = "";

　　var password ="";

　　clientContext.Credentials = new NetworkCredential(username,password,domain);

　　clientContext.Credentials = CredentialCache.DefaultCredentials;

　　Guid listId = new Guid("A9999---");

　　Web web = clientContext.Web;

　　List docList = web.Lists.GetById(listId);

　　CamlQuery camlQuery = new CamlQuery();

　　camlQuery.ViewXml = "";

　　ListItemCollection items = docList.GetItems(camlQuery);

　　clientContext.Load(docList);

　　clientContext.Load(items);

　　clientContex.ExecuteQuery();

　　int count = 1;

　　foreach(var item in items)

　　{

　　Console.WriteLine("共"+items.Count + "个");

　　SP. File file = item.Fiel;

　　clientContext.Load(file);

　　clientContex.Load(web);

　　clientContex.ExecuteQuery();

　　string destLocation = "/site/library/folder/"+file.name;

　　//FileInfomation fileInfo = SP.File.OpenBinaryDirect(clientContex,file.ServierRelativeUrl);

　　//SP.File.SaveBinaryDirect(clientContex,destLocation,fileInfo.Stream,true);

　　if(item.FileSystemObjectType == FileSytemObjectType.File)

　　{

　　file.MoveTo(destLocation,MoveOperations.Overwrite);

　　clientContex.ExecuteQuery();

　　var uploadfile = clientContext.Web.GetFileByServerRelatioveUrl(destLocation);

　　var listitem = uploadfile.ListItemAllFields;

　　listitem["ContentTypeId"] = "0x0....";

　　listitem.Update();

　　clientContext.ExecuteQuery();

  　 count ++;

　　clientContext.Dispose();

　　Console.WriteLine("完成。")

       }catch(Exception e)

　　{

　　Console.WriteLine("{0}",e.Message);

　　return;

　　}

}

下载文档的方法：

FileInformation fInfo = SP.File.OpenBinaryDirect(clientContext,item["FileRef").ToString();

stream s= fInfo.Stream;

string saveTo=@"D:\folder"+filename;

FileStream writeStream = new FileStream(saveTo,FileMode.Create,FileAccess.Write);

ReadWriteStream(s,writeStream);
