upload azure blob using UploadFromStreamAsync Method

Question

Problem

I am trying to generate Pdf and create MemoryStream object and trying to upload that stream to azure Blob Storage. I am already tried the below code so far but the blob is not uploaded to azure and also what is the name of that blob which I upload using stream method of azure sdk

Code

var memoryStream = new MemoryStream(byteArray, 0, byteArray.Length);
var cred = new StorageCredentials("foo", "key");
var account = new CloudStorageAccount(cred, true);
var client = account.CreateCloudBlobClient();
var container = client.GetContainerReference("container");
CloudBlockBlob sourceBlob = container.GetBlockBlobReference("foo/bar");
var attachment =  sourceBlob.UploadFromStreamAsync(memoryStream);

First thing that stands out is the missing await on the call to UploadFromStreamAsync. — Kirk Larkin

As @Kirk has said, use await sourceBlob.UploadFromStreamAsync(memoryStream); instead of var attachment = sourceBlob.UploadFromStreamAsync(memoryStream); Or your code will exit before upload is finished.

Note that your method should change to public async Task methodname(), you will see related tip shown by VS.

Some references for you

And see container.GetBlockBlobReference("blobname"); the string you use to get blob reference is the name of blob uploaded.
