I have BlobServiceAsyncClient

Used TenantID, clientID, ClientSecret, ContainerName for creating the blobContainerAsyncClient.

Uploading file as

blobContainerAsyncClient.getBlobAsyncClient(fileName).upload(.........);

Answer 1

You can use the below code

creates a Shared Access Signature with Read only permission and available only for the next 10 minutes.

public string CreateSAS(string blobName)

{
    var container = blobClient.GetContainerReference(ContainerName);

    // Create the container if it doesn't already exist
    container.CreateIfNotExists();

    var blob = container.GetBlockBlobReference(blobName);

    var sas = blob.GetSharedAccessSignature(new SharedAccessBlobPolicy()
    {
        Permissions = SharedAccessBlobPermissions.READ,
        SharedAccessExpiryTime = DateTime.UtcNow.AddMinutes(10),
    });

    return sas;
}
