标题: SharePoint System.Net.WebException:“远程服务器返回错误: (414) REQUES
SharePoint CSOM执行下面代码时报错：
string fileServerRelativeUrl = "/xxxx/2003249_98.RXE";
  1. using (var fileInfo = Microsoft.SharePoint.Client.File.OpenBinaryDirect(ctxOriginal, fileServerRelativeUrl))
  2. using (var reader = new StreamReader(fileInfo.Stream))
  3. {
  4.     Microsoft.SharePoint.Client.File.SaveBinaryDirect(
  5.     //Client Context
  6.     ctxTarget,
  7.     // Server relative url of the document
  8.     //listTarget.RootFolder.ServerRelativeUrl + file.ServerRelativeUrl.Replace(libraryServerRelativeUrlOriginal,""),//新路径
  9.     fileServerRelativeUrlTarget,
  10.     // Content of the file
  11.     reader.BaseStream,
  12.     // Overwrite file if it's already exist
  13.     true);
  14.     ctxTarget.ExecuteQuery();
  15. }
复制代码
 
报：

尝试修改web.config如下
在Web.config文件中添加以下设置。
未能办理。
颠末各种尝试，一篇来自stackoverflow的帖子提醒了我，
“It was a permission problem. The IIS user did not have read-rights to the folder. Changed to use application pool identity instead and now its working.”
我的账号权限充足。颠末查询原来是SharePoint管理中心设置“被禁止的文件类型”导致的。读取的文件是Rxe类型，被禁止了。

CSOM: How to copy a document from one document library to another documents library?

 I have a requirement to copy documents that meets a certain criteria ( i.e once a document's approval status = approved) to an Archived documents library. I am looping through all the sites and using CAML query to filter out the documents with approved status but I have no idea how to copy the document to a different library location using CSOM C# after checking this condition. Also, I need the document to be replaced in case it is already present in the archived library.
Note: The archived library is in a different site collection.
Any help is greatly appreciated. Thank you in advance.
  1. var bookname = item.DisplayName;  
  2. string bookLocation = $"{rootFolder.ServerRelativeUrl}/{bookname}";                                 
  3. var absoluteUrl = new Uri(ctx.Url).GetLeftPart(UriPartial.Authority) + bookLocation;  
  4. var srcUrl = absoluteUrl;
