如何将文件上传到SharePoint文档库

Question

任何人都可以建议我在如何将文件上传到共享点文档库上创建银光沙盒解决方案。我是C＃开发人员。

Answer 1

你可以参考下面的代码：

String UploadFile = @"C:\YourFile.txt"; 
String sharePointWebAdd = "http://yoursite.com/sites/Research/"; 
String docLib = "Shared Documents"; 

using (SPSite oSite = new SPSite(sharePointWebAdd)) 
{ 
    using (SPWeb oWeb = oSite.OpenWeb()) 
    { 
     if (!System.IO.File.Exists(UploadFile)) 
      throw new FileNotFoundException("File not found.", UploadFile);      

     SPFolder myLibrary = oWeb.Folders[docLib]; 

     // Prepare to upload 
     Boolean replaceExistingFiles = true; 
     String fileName = System.IO.Path.GetFileName(UploadFile); 
     FileStream fileStream = File.OpenRead(UploadFile); 

     // Upload document 
     SPFile spfile = myLibrary.Files.Add(fileName, fileStream, replaceExistingFiles); 

     // Commit 
     myLibrary.Update(); 
    } 
}

一点很难在这里描述了。但我认为你会从文件中获得FileInfo。对于银光应用程序，您需要添加两个客户端对象模型的引用dll。

Microsoft.SharePoint.Client.Silverlight.dll. 
Microsoft.SharePoint.Client.Silverlight.Runtime.dll. 

你可以从C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS\ClientBin目录路径找到上面的dll。

private ClientContext context; 
private Web web; 

private void UploadFile(FileInfo fileToUpload, string libraryTitle, string subfolderPath, bool fileOverwrite) 
    { 
     try 
     { 
      //Treatment of files and loading it to byte array [] 
      Stream str = null; 
      Int32 strLen, strRead; 

      str = fileToUpload.OpenRead(); 
      strLen = Convert.ToInt32(str.Length); 

      byte[] strArr = new byte[strLen]; 
      strRead = str.Read(strArr, 0, strLen); 

      using (context = new ClientContext("http://localhost/")) 
      { 
      web = context.Web; 

      //Defining where to find the files to tape record the library go 
      List destinationList = web.Lists.GetByTitle(libraryTitle); 

      //Creating a file 
      var fciFileToUpload = new FileCreationInformation(); 
      fciFileToUpload.Content = strArr; 

      //Must determine whether to upload files directly to the library or whether to upload the files to sub directories and stack your way to the file 
      string uploadLocation = fileToUpload.Name; 

      if (!string.IsNullOrEmpty(subfolderPath)) 
      { 
       uploadLocation = string.Format("{0}/{1}", subfolderPath, uploadLocation); 
      } 
      uploadLocation = string.Format("{0}/{1}/{2}", webUrl, libraryTitle, uploadLocation); 

      //Sets the path to the file where you want to upload and subor whether to overwrite the file or not 
      fciFileToUpload.Url = uploadLocation; 
      fciFileToUpload.Overwrite = fileOverwrite; 

      clFileToUpload = destinationList.RootFolder.Files.Add(fciFileToUpload); 

      //load web,list. 
      context.Load(web); 
      context.Load(destinationList, list => list.ItemCount); 
      context.Load(clFileToUpload); 
      context.Load(clFileToUpload.ListItemAllFields); 
      context.ExecuteQueryAsync(OnLoadingSucceeded, OnLoadingFailed); 
      } 
     } 
     catch (Exception ex) 
     { 
      MessageBox.Show(ex.Message); 
      unhideComponents(); 
     } 
    } 
    private void OnLoadingSucceeded(Object sender, ClientRequestSucceededEventArgs args) 
    { 
     Dispatcher.BeginInvoke(fileUploaded); // fileUploaded is function 
    } 

    private void OnLoadingFailed(object sender, ClientRequestFailedEventArgs args) 
    { 
     Dispatcher.BeginInvoke(fileNotUploaded); //fileNotUploaded is function 
    }
