public class UploadPartRequest : AmazonWebServiceRequest IRequestEvents
The UploadPartRequest type exposes the following members
Name | Description | |
---|---|---|
UploadPartRequest() |
Name | Type | Description | |
---|---|---|---|
BucketName | System.String | The name of the bucket containing the object to receive the part. | |
FilePath | System.String |
Full path and name of a file from which the content for the part is retrieved. For WinRT and Windows Phone this property must be in the form of "ms-appdata:///local/file.txt". |
|
FilePosition | System.Int64 | Position in the file specified by FilePath from which to retrieve the content of the part. This field is required when a file path is specified. It is ignored when using the InputStream property. | |
InputStream | System.IO.Stream | Input stream for the request; content for the request will be read from the stream. | |
IsLastPart | System.Boolean | Caller needs to set this to true when uploading the last part. This property only needs to be set when using the AmazonS3EncryptionClient. | |
Key | System.String | The key of the object. | |
MD5Digest | System.String | An MD5 digest for the part. | |
PartNumber | System.Int32 | Part number of part being uploaded. | |
PartSize | System.Int64 | The size of the part to be uploaded. | |
ReadWriteTimeout | System.Nullable<System.TimeSpan> | Overrides the default ReadWriteTimeout value. | |
ServerSideEncryptionCustomerMethod | Amazon.S3.ServerSideEncryptionCustomerMethod | The Server-side encryption algorithm to be used with the customer provided key. | |
ServerSideEncryptionCustomerProvidedKey | System.String |
The base64-encoded encryption key for Amazon S3 to use to encrypt the object
Using the encryption key you provide as part of your request Amazon S3 manages both the encryption, as it writes to disks, and decryption, when you access your objects. Therefore, you don't need to maintain any data encryption code. The only thing you do is manage the encryption keys you provide. When you retrieve an object, you must provide the same encryption key as part of your request. Amazon S3 first verifies the encryption key you provided matches, and then decrypts the object before returning the object data to you. Important: Amazon S3 does not store the encryption key you provide. |
|
ServerSideEncryptionCustomerProvidedKeyMD5 | System.String | The MD5 of the customer encryption key specified in the ServerSideEncryptionCustomerProvidedKey property. The MD5 is base 64 encoded. This field is optional, the SDK will calculate the MD5 if this is not set. | |
StreamTransferProgress | System.EventHandler<Amazon.Runtime.StreamTransferProgressArgs> | Attach a callback that will be called as data is being sent to the AWS Service. | |
Timeout | System.Nullable<System.TimeSpan> | Overrides the default request timeout value. | |
UploadId | System.String | Upload ID identifying the multipart upload whose part is being uploaded. |
This example shows how to upload 13MB of data using mutlipart upload.
The data is contained in a stream and the upload is done in 3 parts:
5MB, 5MB, then the remainder.
int MB = (int)Math.Pow(2, 20); // Create a client AmazonS3Client client = new AmazonS3Client(); // Define input stream Stream inputStream = Create13MBDataStream(); // Initiate multipart upload InitiateMultipartUploadRequest initRequest = new InitiateMultipartUploadRequest { BucketName = "SampleBucket", Key = "Item1" }; InitiateMultipartUploadResponse initResponse = client.InitiateMultipartUpload(initRequest); // Upload part 1 UploadPartRequest uploadRequest = new UploadPartRequest { BucketName = "SampleBucket", Key = "Item1", UploadId = initResponse.UploadId, PartNumber = 1, PartSize = 5 * MB, InputStream = inputStream }; UploadPartResponse up1Response = client.UploadPart(uploadRequest); // Upload part 2 uploadRequest = new UploadPartRequest { BucketName = "SampleBucket", Key = "Item1", UploadId = initResponse.UploadId, PartNumber = 2, PartSize = 5 * MB, InputStream = inputStream }; UploadPartResponse up2Response = client.UploadPart(uploadRequest); // Upload part 3 uploadRequest = new UploadPartRequest { BucketName = "SampleBucket", Key = "Item1", UploadId = initResponse.UploadId, PartNumber = 3, InputStream = inputStream }; UploadPartResponse up3Response = client.UploadPart(uploadRequest); // List parts for current upload ListPartsRequest listPartRequest = new ListPartsRequest { BucketName = "SampleBucket", Key = "Item1", UploadId = initResponse.UploadId }; ListPartsResponse listPartResponse = client.ListParts(listPartRequest); Debug.Assert(listPartResponse.Parts.Count == 3); // Complete the multipart upload CompleteMultipartUploadRequest compRequest = new CompleteMultipartUploadRequest { BucketName = "SampleBucket", Key = "Item1", UploadId = initResponse.UploadId, PartETags = new List<PartETag> { new PartETag { ETag = up1Response.ETag, PartNumber = 1 }, new PartETag { ETag = up2Response.ETag, PartNumber = 2 }, new PartETag { ETag = up3Response.ETag, PartNumber = 3 } } }; CompleteMultipartUploadResponse compResponse = client.CompleteMultipartUpload(compRequest);
If PartSize is not specified then the rest of the content from the file or stream will be sent to Amazon S3.
You must set either the FilePath or InputStream. If FilePath is set then the FilePosition property must be set.
