SharePoint--简单的文件复制

思路

通过用户名密码登录SharePoint后，获取Title为Documents的列表项下的根文件夹。在根文件夹下查找是否存在文件要复制到的地址，不存在的话就创建一个对应的文件夹。创建好之后，将要复制文件的地址中文件逐个的进行复制。思路比较简单，但是API比较难找，找了一点时间才找到对应的API。

代码

	/// 
/// 简单的文件复制/// 
/// SharePoint网址/// 用户名/// 密码/// 复制前的文件名/// 复制到的文件名private static void copy(string SPOUrl, string userName, SecureString password, String copyFromFolderName, String copyToFolderName){Folder folderFrom;List files = new List();try{using (var context = new ClientContext(SPOUrl)){context.Credentials = new SharePointOnlineCredentials(userName, password);Web oWeb = context.Web;ListCollection lc = oWeb.Lists;List itemsCollection = oWeb.Lists.GetByTitle("Documents");Folder root = itemsCollection.RootFolder;FolderCollection fdc = root.Folders;context.Load(fdc);context.ExecuteQuery();foreach (Folder fd in fdc){context.Load(fd);context.ExecuteQuery();}var b = fdc.Where(fd => fd.Name == copyToFolderName);var a = fdc.Where(fd => fd.Name == copyFromFolderName);folderFrom = a.First();var x = b.ToArray();if (x.Length == 0){ResourcePath rp = ResourcePath.FromDecodedUrl(copyToFolderName);root.AddSubFolderUsingPath(rp);context.ExecuteQuery();}FileCollection fc = folderFrom.Files;context.Load(fc);context.ExecuteQuery();foreach (Microsoft.SharePoint.Client.File f in fc){context.Load(f);context.ExecuteQuery();f.CopyTo($"{SPOUrl}Shared Documents/{copyToFolderName}/{f.Name}", true);context.ExecuteQuery();}}}catch (Exception e){Console.WriteLine(e.Message);}}

在每次需要使用上一级对象的属性对象时，都需要对下一级对象进行context.Load()操作，要不然会出现报错现象，在每次读取或者更新时，需要执行ExecuteQuery()方法。
