Hey all,

I'm trying to upload the file icon from a blob that is already uploaded. I'm using sasuri for the existing blob, (the one i want to upload the fileicon for).

Something like this:

//sasuri function
            var SASURI = GetUploadedFileIconSASURL(blobnamehere);

//retrieving fileicon for that blob
            var fileIcon = System.Drawing.Icon.ExtractAssociatedIcon(SASURI);

//and then somehow upload the icon as a new blob??

            CloudBlobContainer blobContainer = CloudStorageServices.GetCloudBlobContainer();
            CloudBlockBlob blockBlob = blobContainer.GetBlockBlobReference(blobiconnamehere);

            using (var stream = fileIcon.Openread())
            {
                blockBlob.UploadFromStream(stream);
            }

How can I upload a blockblob from a variabel like that? The stream is incorrect, does not contain a definition for OpenRead. (Im a newbie bare with me!)

Also, in theory, would this work? Will the icon be saved as a image?

Thanks in advance!!


Update 1:



var SASURI = GetUploadedFileIconSASURL(existingBlobNameHere);

var fileIcon = System.Drawing.Icon.ExtractAssociatedIcon(@"C:\WINDOWS\system32\notepad.exe");

CloudBlobContainer blobContainer = CloudStorageServices.GetCloudBlobContainer();
CloudBlockBlob blockBlob = blobContainer.GetBlockBlobReference(blobiconnamehere);


Bitmap bmpIcon = fileIcon.ToBitmap();

using (System.IO.MemoryStream ms = new System.IO.MemoryStream())
{
bmpIcon.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
blockBlob.UploadFromStream(ms);
}

Its running but the file icon blob is null(?)
