After storing media on azur blob url,media is not retrieving

Question

Hi, I want upload multiple media on azure blob so what i did. 1] create a byte array and store all the media in that array and pass this byte array to controller via Ajax call, before send that byte array i have converted into base 64 binary to array string. them make ajax call. 2] On controller i fetched the data and decode that base 64 binary to array string into byte array. 3] i got byte array and create MemoryStream using this byte array,and uploaded media on blob. 4] But when i am trying to get that media from that blob url i didn't get the media and show status :- "Failed to load resource: the server responded with a status of 400 (One of the request inputs is out of range". So what i am doing wrong please let me know as soon as posible Here i am attaching my code Thanks & Regards, Deeksha rahangdale

In MVC you will get byte array(base64 code) in controller right , convert byte array to file (with respctive format ) . example code public Image byteArrayToImage(byte[] byteArrayIn) { MemoryStream ms = new MemoryStream(byteArrayIn); Image returnImage = Image.FromStream(ms); return returnImage; } then upload you file to azure storage and save the file name in database , while retriving htttp://azureblobstorage/filename/jpg string storageConnection = CloudConfigurationManager.GetSetting("BlobStorageConnectionString"); CloudStorageAccount cloudStorageAccount = CloudStorageAccount.Parse(storageConnection); //create a block blob CloudBlobClient cloudBlobClient = cloudStorageAccount.CreateCloudBlobClient(); //create a container CloudBlobContainer cloudBlobContainer = cloudBlobClient.GetContainerReference("appcontainer"); //create a container if it is not already exists if (await cloudBlobContainer.CreateIfNotExistsAsync()) { await cloudBlobContainer.SetPermissionsAsync(new BlobContainerPermissions { PublicAccess = BlobContainerPublicAccessType.Blob }); } string imageName = "Test-" + Path.GetExtension(imageToUpload.FileName); //get Blob reference CloudBlockBlob cloudBlockBlob = cloudBlobContainer.GetBlockBlobReference(imageName); cloudBlockBlob.Properties.ContentType = imageToUpload.ContentType; await cloudBlockBlob.UploadFromStreamAsync(imageToUpload.InputStream); Download File from Azure Blob using C# var containerName = "testcontainerherbi"; string storageConnection = CloudConfigurationManager.GetSetting("BlobStorageConnectionString"); CloudStorageAccount cloudStorageAccount = CloudStorageAccount.Parse(storageConnection); CloudBlobClient blobClient = cloudStorageAccount.CreateCloudBlobClient(); CloudBlobContainer cloudBlobContainer = blobClient.GetContainerReference(containerName); CloudBlockBlob blockBlob = cloudBlobContainer.GetBlockBlobReference("uploadedfilename.ext"); MemoryStream memStream = new MemoryStream(); blockBlob.DownloadToStream(memStream); HttpContext.Current.Response.ContentType = blockBlob.Properties.ContentType.ToString(); HttpContext.Current.Response.AddHeader("Content-Disposition", "Attachment; filename=" + blockBlob.ToString()); HttpContext.Current.Response.AddHeader("Content-Length", blockBlob.Properties.Length.ToString()); HttpContext.Current.Response.BinaryWrite(memStream.ToArray()); HttpContext.Current.Response.Flush(); HttpContext.Current.Response.Close();
