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

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,

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();
