如何创建和上传文件到亚马逊S3

Question

我有一个C＃lambda函数创建一个简单的.txt文件是这样的：

string file = Path.DirectorySeparatorChar + "tmp" + Path.DirectorySeparatorChar + "file.txt"; 
File.Create(file); 

然后我试图把它上传到S3

TransferUtility fileTransferUtility = new TransferUtility(new AmazonS3Client(Amazon.RegionEndpoint.EUWest1)); 
fileTransferUtility.Upload(file, MyBucketNameInString); 

但是，它返回这个错误：

File createdOne or more errors occurred. (The process cannot access the file '/tmp/file.txt' because it is being used by another process.): AggregateException

任何解决方案吗？

我SIMPL解决上传文件到Amazon S3

private void AddFile(Stream image) 
{ 
    InitializeKey(); 
    var uploadRequest = new TransferUtilityUploadRequest(); 
    uploadRequest.CannedACL = S3CannedACL.PublicRead; 
    uploadRequest.InputStream = image; 
    uploadRequest.BucketName = AppConfiguration.AmazonS3FileBucketName; 
    uploadRequest.Key = _key; 

    using (TransferUtility fileTransferUtility = new TransferUtility(_client)) 
    { 
     fileTransferUtility.Upload(uploadRequest); 
    } 
}
