Question

我正在开发一个控制台应用程序，用以下代码片段从S3存储桶下载文件：

using (client = new AmazonS3Client(Amazon.RegionEndpoint.USEast1))
{
     GetObjectRequest request = new GetObjectRequest
     {
          BucketName = bucketName,
          Key = keyName
     };

     using (GetObjectResponse response = client.GetObject(request))
     {
          string dest = Path.Combine(workingDirectory, keyName);
          if (!File.Exists(dest))
          {
               response.WriteResponseStreamToFile(dest);
               System.Diagnostics.Debug.WriteLine(response.HttpStatusCode);
          }

      }
 }

workingDirectory变量是：

string workingDirectory = Directory.GetCurrentDirectory() + "\\rawfiles";

我得到 访问路径被拒绝错误 这是以下堆栈跟踪

'System.IO .__ Error.WinIOError（Int32 errorCode，String maybeFullPath） at System.IO.FileStream.Init（String path，FileMode mode，FileAccess access，Int32 rights，Boolean useRights，FileShare share，Int32 bufferSize，FileOptions options，SECURITY_ATTRIBUTES secAttrs，String msgPath，Boolean bFromProxy，Boolean useLongPath，Boolean checkHost）在System.IO.FileStream..ctor（字符串路径，FileMode模式，FileAccess访问，FileShare共享，Int32 bufferSize）在Amazon.S3.Model.GetObjectResponse.WriteResponseStreamToFile（String filePath，Boolean append）在Amazon.S3.Model.GetObjectResponse.WriteResponseStreamToFile（String filePath）在AmazonObject.classes.DownloadS3Object_class.GetObject（String bucketName，String keyName，String workingDirectory）中的c：\ Users \ user1 \ Documents \ Visual Studio 2013 \ Projects \ Web Projects \ myr_cron \ myr_cron \ DownloadS3Object_class.cs：第45行

第45行是这样的：

response.WriteResponseStreamToFile(dest);

我该如何解决这个问题？
