Question

我有一个Windows应用程序，可以将.pdfs保存到SharePoint文档库。除了这个文件，它工作正常。每当我在这个10.1MB文件中使用SaveBinaryDirect时，我都会遇到以下异常：

System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: An established connection was aborted by the software in your host machine. ---> System.Net.Sockets.SocketException: An established connection was aborted by the software in your host machine
   at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags)
   at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size)
   --- End of inner exception stack trace ---
   at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size)
   at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size)
   at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead)
   --- End of inner exception stack trace ---
   at System.Net.HttpWebRequest.GetResponse()
   at Microsoft.SharePoint.Client.SPWebRequestExecutor.Execute()
   at Microsoft.SharePoint.Client.File.SaveBinary(ClientContext context, String serverRelativeUrl, Stream stream, String etag, Boolean overwriteIfExists, SaveBinaryCheckMode checkMode)
   at Microsoft.SharePoint.Client.File.SaveBinaryDirect(ClientContext context, String serverRelativeUrl, Stream stream, Boolean overwriteIfExists)
   at BKWatch.BKWatchViewModel.UploadDocument(String siteURL, String documentListName, String documentListURL, String documentName, Byte[] documentStream, Int64 AccountId, String DebtorName, Nullable`1 Pages, String Title)

我已经尝试了以下内容：

clientContext.PendingRequest.RequestExecutor.WebRequest.KeepAlive = false;

System.Net.ServicePointManager.MaxServicePointIdleTime = 600000;
 clientContext.RequestTimeout = 600000;

增加SharePoint中的最大大小 - 已经达到50 MB 增加IIS web.config中的最大大小 - 已经是2GB

感谢。

Answer 1

经过与Microsoft的几次长时间电话交谈之后，他们认为SaveBinaryDirect代码中存在一个错误，并建议我使用ClientObject.Add功能。似乎到目前为止工作。

Answer 2

我在连续上传大量文件时遇到了Microsoft.SharePoint.Client.File.SaveBinaryDirect的这个问题。

对此的修复是在每次使用SaveBinaryDirect时，使用try-catch包装它，并捕获System.Net.WebException。

捕获Webexception后，运行您之前运行的相同SaveBinaryDirect命令，它应该可以正常工作。
