public ActionResult Createnewcar(FormCollection collection, ProductsHondaofConyers2 p, HttpPostedFileBase[] MultipleFiles,TagTable tb)
{
try
{
// TODO: Add insert logic here

var Tagid = collection["TagNo"];

var qry = (from c in db.ProductsHondaofConyers2s where c.TagNo ==Tagid select c).Count();


if (qry != 1)
{
foreach (var fileBase in MultipleFiles)
{
if (fileBase.ContentLength > 0)
{
Microsoft.WindowsAzure.StorageClient.CloudBlobContainer blobContainer = _myBlobStorageService.GetCloudBlobContainer();
CloudBlob blob = blobContainer.GetBlobReference(fileBase.FileName);
blob.UploadFromStream(fileBase.InputStream);
}
}


List<string> blobs = new List<string>();

foreach (var fileBase in MultipleFiles)
{
Microsoft.WindowsAzure.StorageClient.CloudBlobContainer blobContainer1 = _myBlobStorageService.GetCloudBlobContainer();

CloudBlob blob1 = blobContainer1.GetBlobReference(fileBase.FileName);

blobs.Add(blob1.Uri.ToString());
}

p.ProductImage = blobs.ElementAt(0).ToString();
p.ProductImage1 = blobs.ElementAt(1).ToString();
}

So,is it requirement that you have to insert same image again and again? if yes. then take Guid field,and based on guid,insert images.
