System.Net.ProtocolViolationException：要写入流的字节数超过指定的Content-Length字节大小

Question

使用AWSSDK.dll我试图在zip文件中循环播放图像，并使用下面的代码将它们发送到亚马逊S3。问题是我一直收到错误

System.Net.ProtocolViolationException 

当我调用fileTransferUtility.Upload()方法时。 zip将HttpPostedFile发布到用于创建zip文件的方法，然后遍历每个条目并上传。

ZipFile zipFile = new ZipFile(postedFile.InputStream);

foreach (ZipEntry zipEntry in zipFile)
{

    if (zipEntry.Name != String.Empty)
    {
        string saveLocation = unzipBaseDir + "/" + zipEntry.Name;
        string dbLocation = "./" + Path.Combine(unzipBaseDir, zipEntry.Name).Replace(@"\", "/");

        // save the file

        TransferUtilityConfig config = new TransferUtilityConfig();
        config.MinSizeBeforePartUpload = 80740;

        TransferUtility fileTransferUtility = new TransferUtility(new AmazonS3Client(accessKeyID, secretAccessKeyID, RegionEndpoint.EUWest1), config);


        using (Stream fileToUpload = zipFile.GetInputStream(zipEntry))
        {

            TransferUtilityUploadRequest fileTransferUtilityRequest = new TransferUtilityUploadRequest
            {
                BucketName = existingBucketName,
                InputStream = fileToUpload,
                StorageClass = S3StorageClass.Standard,
                PartSize = fileToUpload.Length,
                Key = saveLocation,
                CannedACL = S3CannedACL.PublicRead

            };

            fileTransferUtility.Upload(fileTransferUtilityRequest);
        }

    }
}
