I just started the Quickstart with .NET v12 SDK https://learn.microsoft.com/da-dk/azure/storage/blobs/storage-quickstart-blobs-dotnet

But i cant seem to find out how to specify a ContentType when uploading a blob.

Does anyone know that?

Thanks in advance.

You can set it as follows,

 await blobClient.UploadAsync(stream, true, default);
 await blobClient.SetHttpHeadersAsync(new BlobHttpHeaders
 {
    ContentType = contentType
 });

EDIT: As mentioned in the comment, the efficient way to do the same with a single method as follows,

await blobClient.UploadAsync(ms, new BlobHttpHeaders{ ContentType = "text/plain"});

Thanks you so much Sajeetharan! I also just found out that you can upload the blob and specify ContentType with one single call "await blobClient.UploadAsync(ms, new BlobHttpHeaders{ ContentType = "text/plain" });"

Please try this override of UploadAsync method. This method will upload and set the content type in a single network call.

Here would be your code:

var httpHeaders = new BlobHttpHeaders
 {
    ContentType = contentType
 });
await blobClient.UploadAsync(stream, httpHeaders);

With this override of UploadAsync, it's also possible to set the metadata for the blob.
@AmélieDupré - Overload takes an instance of BlobUploadOptions, which facilitates Metadata. See: learn.microsoft.com/en-us/dotnet/api/…
