檢索文件集合並將它們保存到本地目錄

我遇到問題，將圖片的Sharepoint文件集合保存到本地目錄。我對Sharepoint 2016非常新，我遇到了解決此問題的問題。好像當我運行這段代碼時，它會首先給我提供我的文件集合的第一個映像。但是，當我查看目標目錄時，映像是0字節（只是一個空文件）。它保持運行一段時間後會引發以下異常錯誤。檢索文件集合並將它們保存到本地目錄

Error:
Additional information: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

public static void ImageRetrival(DHG.OneDrive.Helpers.OneDriveHelper oneDrive, string user) 
{ 
    try 
    { 
     var wb = userContext.Web; 
     userContext.Load(wb); 
     var files = oneDrive.GetOneDriveFilesByFolderName(user); 
     var test = Microsoft.SharePoint.Client.File.OpenBinaryDirect(userContext, wb.ServerRelativeUrl); 
     FileStream fs = null; 

     if (files != null) 
     { 
      foreach (var file in files) 
      { 
       var fileName = file.Name.ToString(); 
       string path = @"C:\Top-Level\" + fileName; 
       fs = new FileStream(path, FileMode.OpenOrCreate, FileAccess.ReadWrite); 
       test.Stream.CopyTo(fs); 
      } 
     } 
    } 
    catch (Exception e) 
    { 
     throw e; 
    } 
}

看看@JonSkeets例如這看起來是在我看來，很多清潔http://stackoverflow.com/questions/5730863/how-to-use-stream-copyto- on-net-framework-3-5 – MethodMan

@方法男人，我得到它的工作是更合乎邏輯的序列，而不是代碼。請看看更正。 – EasyE

好理解了它，邏輯是錯的，我有以下行超出了我爲其使其空的時候我打電話回去在每個代碼中的每個循環。這就是我的文件以0字節出現的原因。

更正後的代碼

public static void ImageRetrival(PHG.OneDrive.Helpers.OneDriveHelper oneDrive, string user) 
    { 

     try 
     { 
      var wb = userContext.Web; 
      userContext.Load(wb); 
      var files = oneDrive.GetOneDriveFilesByFolderName(user); 

      if (files != null) 
      { 

       foreach (var file in files) 
       { 
        // has to be inside my foreach loop referencing file in files which represents a sharepoint filecollection 
        var fileinfo = Microsoft.SharePoint.Client.File.OpenBinaryDirect(userContext, file.ServerRelativeUrl); 
        var fileName = file.Name.ToString(); 
        string path = @"C:\Top-Level\" + fileName; 
        using (var fs = new FileStream(path, FileMode.OpenOrCreate, FileAccess.ReadWrite)) 
        { 
         fileinfo.Stream.CopyTo(fs); 
        } 

       } 
      } 

     } 
     catch (Exception e) 
     { 
      throw e; 
     } 

    }
