Parameters

cache

The cache containing the document. This value cannot be null.

uri

URI to the owner document of the annotations to download.

offset

0-based byte offset into the source annotations data at which to begin reading the data.

data

Buffer to read the data into.

dataOffset

0-based byte offset into data at which to begin storing the data.

dataLength

The maximum number of bytes to read.

Return Value

The total number of bytes read into data. This can be less than the number of bytes requested by dataLength, if that many bytes are not currently available, or zero (0) if the end of the data has been reached.

Remarks

Similar to UploadDocument, data can be downloaded in chunks or all at once. Refer to Uploading Using the Document Library for detailed information on how to use these methods and the various options used.

GetDocumentCacheInfo can be used to determine if a document is in the cache and to get its information.

DownloadDocument can be used to download the data of a document.

Example

For an example, refer to DownloadDocument(ObjectCache,string,long,int,Stream).
