使用camlQuery的Sharepoint 2010客户端对象模型 – 文件下载但没有内容/ 0字节

我正在尝试从文档库中的文件夹中的子文件夹下载txt文件。

我正在使用camlQuery来实现这一目标。 不幸的是，我没有得到txt文件的内容。 它有0个字节。

public void SaveFolderFiles(string fileName, string libraryName, ClientOM.ClientContext clientContext) { ClientOM.List sharedDocumentsList = clientContext.Web.Lists.GetByTitle(libraryName); ClientOM.CamlQuery camlQuery = new ClientOM.CamlQuery(); camlQuery.FolderServerRelativeUrl = "/Site/Folder/Folder2010/"; camlQuery.ViewXml = @"     " + fileName + @"   1  "; ClientOM.ListItemCollection listItems = sharedDocumentsList.GetItems(camlQuery); clientContext.Load(sharedDocumentsList); clientContext.Load(listItems); clientContext.ExecuteQuery(); if (listItems.Count == 1) { ClientOM.ListItem item = listItems[0]; Console.WriteLine("FileLeafRef: {0}", item["FileLeafRef"]); Console.WriteLine("FileDirRef: {0}", item["FileDirRef"]); Console.WriteLine("FileRef: {0}", item["FileRef"]); Console.WriteLine("File Type: {0}", item["File_x0020_Type"]); ClientOM.FileInformation fileInformation = ClientOM.File.OpenBinaryDirect(clientContext, (string)item["FileRef"]); using (MemoryStream memoryStream = new MemoryStream()) { fileInformation.Stream.CopyTo(memoryStream); using (FileStream fileStream = File.Create(@"D:\" + item["FileLeafRef"].ToString())) { memoryStream.CopyTo(fileStream); } memoryStream.Flush(); } } else { Console.WriteLine("Document not found."); } } 

也许有人有想法？

试试这个：

使用FileInformation并获取MemoryStream

 string fileurl = (string)liitem["FileRef"]; FileInformation ffl = Microsoft.SharePoint.Client.File.OpenBinaryDirect(clientContext, fileurl); byte[] bytesarr = ReadFully(ffl.Stream); MemoryStream mnm = new MemoryStream(bytesarr); 

ReadFully函数将Stream转换为Bytes array

  public byte[] ReadFully(Stream input) { byte[] buffer = new byte[16 * 1024]; using (MemoryStream ms = new MemoryStream()) { int read; while ((read = input.Read(buffer, 0, buffer.Length)) > 0) { ms.Write(buffer, 0, read); } return ms.ToArray(); } }

直接导出到输出文件…我认为这是最简单，最简单的方法。

 FileInformation fInfo = File.OpenBinaryDirect(currentSiteContext, ServerRelativeURL); System.IO.FileStream outPutFile = System.IO.File.OpenWrite(string.Concat(OutputPath, "\\", DocumentName)); fInfo.Stream.CopyTo(outPutFile); fInfo.Stream.Close(); outPutFile.Close();
