将base64字符串转换为jpg /文件

Question

I am struggling to find a way to convert a base 64 string to a jpeg or a file without using the Image class. Is it possible to create the file and not save it locally and upload to Azure blob storage?

var bytes = Convert.FromBase64String(base64String);

Answer 1

To keep it completely clean and simple, use something like this:

using (var img = new MemoryStream(bytes))
{
    cloudBlockBlob.UploadFromStream(img);
}

This creates a MemoryStream that you can use to call CloudBlockBlob.UploadFromStream() .

Edit
Or, like @mike-z said in the comment below, you can use CloudBlockBlob.UploadFromByteArray() directly.
