Upload Files To Azure BLOB From D365 FO

Uploading attachment file to Microsoft azure storage account blob.

1.           Goto https://portal.azure.com
2.             Goto Storage Account
   
3. Click on Add 

   
   
   
4. Fill details and click Review + Create
   
5. Click on create. It will deploy the storage account.
6. Go to newly created storage account go to access key .
   
   Key 1 and key 2 or connections strings will be used to access this storage account.
   
7. Go to container and click Container
   
8. Fill the name and click ok.
   
9. Now we will create new runnable class in D365FO to upload file to newly created container.
   using Microsoft.WindowsAzure.Storage;
   using Microsoft.WindowsAzure.Storage.Blob;
   
   
   class UploadFileToAzureBlob
   {

                                   blockblob.UploadFromStreamAsync(attachmentStream).Wait();
   
   
                                   blockBlob.FetchAttributes(null,null,null);
                                   BlobProperties BlobProperties = blockblob.Properties;
                                   if(BlobProperties.Length == attachmentStream.Length)
                                   {
                                       info("file uploaded successfully");
                                   }
                               }
   
   
                           }
                       }
                       else
                       {
                           info("file already exists");
                       }
                   }
               }
               else
               {
                   error("unable to connect azure file storage with the provided credentials");
               }
           }
           catch(Exception::Error)
           {
               error("Operation cannot be completed");
           }
           
       }
   
   
   }
   
   
10. Now we will run the class
