Méthode	Description
AddObject ( Stream inputStream, long bytes, string bucketName, string key ) : void	Adds an object to S3 by reading the specified amount of data from the given stream.
AddObject ( Stream inputStream, long bytes, string bucketName, string key, string contentType, CannedAcl acl ) : void	Adds an object to S3 by reading the specified amount of data from the given stream.
AddObject ( Stream inputStream, string bucketName, string key ) : void	Adds an object to S3 by reading all the data in the given stream. The stream must support the Length property.
AddObject ( Stream inputStream, string bucketName, string key, string contentType, CannedAcl acl ) : void	Adds an object to S3 by reading all the data in the given stream. The stream must support the Length property.
AddObject ( string bucketName, string key, long bytes, Action action ) : void	Adds an object to S3 by acquiring the upload stream then allowing the given function to handle writing data into it.
AddObject ( string bucketName, string key, long bytes, string contentType, CannedAcl acl, Action action ) : void	Adds an object to S3 by acquiring the upload stream then allowing the given function to handle writing data into it.
AddObjectString ( string contents, string bucketName, string key ) : void	Uploads the contents of a string to S3. This method is only appropriate for small objects and testing. The UTF-8 encoding will be used.
AddObjectString ( string contents, string bucketName, string key, string contentType, CannedAcl acl ) : void	Uploads the contents of a string to S3. This method is only appropriate for small objects and testing. The UTF-8 encoding will be used.
CopyObject ( string bucketName, string sourceKey, string destKey ) : void	Copies an object within a bucket.
CopyObject ( string bucketName, string sourceKey, string destKey, CannedAcl acl ) : void	Copies an object within a bucket and assigns the given canned ACL.
CopyObject ( string sourceBucketName, string sourceKey, string destBucketName, string destKey ) : void	Copies an object from one bucket to another.
CopyObject ( string sourceBucketName, string sourceKey, string destBucketName, string destKey, CannedAcl acl ) : void	Copies an object from one bucket to another with the given canned ACL.
CreateBucket ( string bucketName ) : void	Creates a bucket in the default storage location automatically determined by Amazon.
CreateBucketInEurope ( string bucketName ) : void	Creates a bucket in the Amazon Europe storage location.
DeleteBucket ( string bucketName ) : void	Deletes the bucket with the given name.
DeleteObject ( string bucketName, string key ) : void	Deletes the object in the specified bucket with the specified key.
ForEachBucket ( Action action ) : void	Performs the given action on each of your buckets without loading the list of buckets completely into memory.
ForEachObject ( string bucketName, Action action ) : void	Queries a bucket for a listing of objects it contains and performs the given action on each object. The DefaultDelimiter will be used.
ForEachObject ( string bucketName, string prefix, Action action ) : void	Queries a bucket for a listing of objects it contains and performs the given action on each object. Only objects with keys beginning with the given prefix will be returned. The DefaultDelimiter will be used.
GetAllBuckets ( ) : IList	Lists all buckets owned by you.
GetAuthorizedUrl ( string bucketName, string key, System.DateTime expires ) : string	Creates a pre-authorized URI valid for performing a GET on the given S3 object in the given bucket. This is useful for constructing a URL to hand over to a 3rd party (such as a web browser). The Uri will automatically expire after the time given. This method itself does not communicate with S3 and will return immediately. You might expect this method to return a System.Uri instead of a string. It turns out there is a tricky issue with constructing Uri objects from these pre-authenticated url strings: The Uri.ToString() method will convert a properly-encoded "+" character back into a raw "+", which is interpreted by Amazon S3 as a space (standard URI conventions). So the signature will be misread if you were to take the Uri.ToString() and feed it to a browser. So instead, we'll give you a properly escaped URL string which will always work in a browser. If you want to, say, use it in a WebRequest instead, it turns out that WebRequest will leave it escaped properly and everything will work.
GetObject ( string bucketName, string key, Stream outputStream ) : void	Gets an existing object in S3 and copies its data to the given Stream.
GetObject ( string bucketName, string key, Stream outputStream, long &contentLength, string &contentType ) : void	Gets an existing object in S3 and copies its data to the given Stream.
GetObjectStream ( string bucketName, string key ) : Stream	Gets a data stream for an existing object in S3. It is your responsibility to close the Stream when you are finished.
GetObjectStream ( string bucketName, string key, long &contentLength, string &contentType ) : Stream	Gets a data stream for an existing object in S3. It is your responsibility to close the Stream when you are finished.
GetObjectString ( string bucketName, string key ) : string	Downloads an existing object in S3 and loads the entire contents into a string. This is only appropriate for very small objects and for testing.
GetObjectString ( string bucketName, string key, string &contentType ) : string	Downloads an existing object in S3 and loads the entire contents into a string. This is only appropriate for very small objects and for testing.
GetUrl ( string bucketName, string key ) : string	This constructs a Uri suitable for accessing the given object in the given bucket. It is not authorized, so it will only work for objects with anonymous read access. This method itself does not communicate with S3 and will return immediately.
IsBucketInEurope ( string bucketName ) : bool	Queries S3 to determine whether the given bucket resides in the Europe location.
ListAllObjects ( string bucketName ) : IEnumerable	Queries a bucket for a listing of all objects it contains. The DefaultDelimiter will be used.
ListAllObjects ( string bucketName, string prefix ) : IEnumerable	Queries a bucket for a listing of objects it contains. Only objects with keys beginning with the given prefix will be returned. The DefaultDelimiter will be used.
ListAllObjects ( string bucketName, string prefix, string delimiter ) : IEnumerable	Queries a bucket for a listing of objects it contains. Only objects with keys beginning with the given prefix will be returned.
ListObjects ( string bucketName, string prefix ) : IList	Queries a bucket for a listing of objects it contains. Only objects with keys beginning with the given prefix will be returned. The DefaultDelimiter will be used. If you expect a large number of objects to be returned, consider using ListAllObjects().
ObjectExists ( string bucketName, string key ) : bool	Returns true if the given object exists in the given bucket.
QueryBucket ( string bucketName ) : BucketAccess	Queries S3 about the existance and ownership of the given bucket name.
S3Service ( ) : System	Creates a new S3Service with the default values.
