(.NET Core C#) Azure Storage: Upload Binary Data to Block Blob using BinData

Sample code to upload binary bytes (contained in a Chilkat BinData object) 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..

// Azure Blob Service Example: Upload binary bytes to a block blob.
// This creates a new block blob or replaces an existing one in its entirety.
// See also: https://msdn.microsoft.com/en-us/library/azure/dd179451.aspx

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

Chilkat.Rest rest = new Chilkat.Rest();

// Connect to the Azure Storage Blob Service
bool bTls = true;
int port = 443;
bool bAutoReconnect = true;
// In this example, the storage account name is "chilkat".
bool success = rest.Connect("chilkat.blob.core.windows.net",port,bTls,bAutoReconnect);
if (success != true) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

// Provide Azure Cloud credentials for the REST call.
Chilkat.AuthAzureStorage azAuth = new Chilkat.AuthAzureStorage();
azAuth.AccessKey = "AZURE_ACCESS_KEY";
// The account name used here should match the 1st part of the domain passed in the call to Connect (above).
azAuth.Account = "chilkat";
azAuth.Scheme = "SharedKey";
azAuth.Service = "Blob";
// This causes the "x-ms-version: 2020-08-04" header to be automatically added.
azAuth.XMsVersion = "2020-08-04";
success = rest.SetAuthAzureStorage(azAuth);

// Note: The application does not need to explicitly set the following
// headers: Content-Length, x-ms-date, Authorization.  These headers
// are automatically set by Chilkat.

// IMPORTANT: Make sure to set the x-ms-blob-type header:
success = rest.AddHeader("x-ms-blob-type","BlockBlob");

// For this example, we'll just load a JPG file into memory..
Chilkat.BinData bd = new Chilkat.BinData();
success = bd.LoadFile("qa_data/jpg/starfish.jpg");
if (success == false) {
    Debug.WriteLine("Failed to load the file to be uploaded.");
    return;
}

// 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..
Chilkat.StringBuilder sbResponseBody = new Chilkat.StringBuilder();
success = rest.FullRequestBd("PUT","/mycontainer/starfish.jpg",bd,sbResponseBody);
if (success == false) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

// When successful, the Azure Storage service will respond with a 201 response status code,
// with no response body.

if (rest.ResponseStatusCode != 201) {
    // Examine the request/response to see what happened.
    Debug.WriteLine("response status code = " + Convert.ToString(rest.ResponseStatusCode));
    Debug.WriteLine("response status text = " + rest.ResponseStatusText);
    Debug.WriteLine("response header: " + rest.ResponseHeader);
    Debug.WriteLine("response body (if any): " + sbResponseBody.GetAsString());
    Debug.WriteLine("---");
    Debug.WriteLine("LastRequestStartLine: " + rest.LastRequestStartLine);
    Debug.WriteLine("LastRequestHeader: " + rest.LastRequestHeader);
    return;
}

Debug.WriteLine("Success.");
