Azure Storage: Upload Binary Data to Block Blob

See more Azure Cloud Storage Examples

Sample code to upload binary bytes to a block blob in Azure Cloud Storage. This creates the block blob, or replaces an existing block blob.

Note: The maximum size of a block blob created by uploading in a single step is 64MB. For larger files, the upload must be broken up into blocks. There is another Chilkat example for that..

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Note: The application does not need to explicitly set the following

// are automatically set by Chilkat.

// IMPORTANT: Make sure to set the x-ms-blob-type header:

// For this example, we'll just load a JPG file into memory..
