System.Configuration.ConfigurationErrorsException在使用Windows服务将文件上传到保管箱期间被捕获

Question

此代码与控制台应用程序正常工作，但我得到错误与Windows服务说配置系统无法初始化（System.Configuration.ConfigurationErrorsException被捕获）

private static async Task Backup() 
    { 
     using (var dbx = new DropboxClient("<REDACTED>")) 
     { 
      string folder = "DropboxUpload"; 
      string file = "setup.exe"; 
      string content = @"D:\Share\setup.exe"; 
      log.Info("Chunk upload file..."); 
      // Chunk size is 100 mb. 
      const int chunkSize = 2 * 1024 * 1024; 
      using (var stream = new FileStream(content, FileMode.Open, FileAccess.Read, FileShare.ReadWrite)) 
      { 
       int numChunks = (int)Math.Ceiling((double)stream.Length/chunkSize); 
       byte[] buffer = new byte[chunkSize]; 
       string sessionId = null; 
       for (var idx = 0; idx < numChunks; idx++) 
       { 
        log.Info("Start uploading chunk {0}" +idx); 
        var byteRead = stream.Read(buffer, 0, chunkSize); 
        using (MemoryStream memStream = new MemoryStream(buffer, 0, byteRead)) 
        { 
         if (stream.Length <= chunkSize) 
         { 
          // here i am getting exception 
         await dbx.Files.UploadAsync(new CommitInfo("/" +folder + "/" + file), body: memStream); 
         } 
         else if (idx == 0) 
         { 
          var result = await dbx.Files.UploadSessionStartAsync(body: memStream); 
          sessionId = result.SessionId; 
         } 
         else 
         { 
          UploadSessionCursor cursor = new UploadSessionCursor(sessionId, (ulong)(chunkSize * idx)); 
          if (idx == numChunks - 1) 
          { 
           await dbx.Files.UploadSessionFinishAsync(cursor, new CommitInfo("/" + folder + "/" + file), memStream); 
           log.Info("BackUp Completed...!!!"); 
          } 
          else 
          { 
           await dbx.Files.UploadSessionAppendV2Async(cursor, body: memStream); 
          } 
         } 
        } 
       } 
      } 
     } 
    }
