Read all Blob List Names from the Windows Azure Containers
The Following snippets is used to read all the Blob list details from the azure containers
and also we can avoid the transport connection error while reading the huge blob list.
by the paging segment concept can able to read large no of blob list...
///////// Getting Blobs List if it's below than 5000 ///////////
TextWriter tw = new StreamWriter ("d:/blob_thumblist.txt" );
int pagingCount = 1000;
CloudStorageAccount storageAccount = CloudStorageAccount .Parse(ConfigurationSettings .AppSettings["CloudStorage" ].ToString());
CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
//Get a reference to the container.
CloudBlobContainer container = blobClient.GetContainerReference("ContainerName" );
///////// Getting Blobs if's below than 5000 ///////////
//Return blobs using a flat listing.
BlobRequestOptions options = new BlobRequestOptions ();
options.UseFlatBlobListing = true ;
////This first operation will return up to 5000 blobs.
ResultSegment <IListBlobItem > resultSegment = container.ListBlobsSegmented(options);
foreach (var blobItem in resultSegment.Results)
{
//writing the blob name into the text file
tw.WriteLine(blobItem.Uri.Segments[2]);
}
//close the stream
tw.Close();
///////// Getting Blobs List if it's more than 5000 ///////////
TextWriter tw = new StreamWriter ("d:/blob_thumblist.txt" );
int pagingCount = 1000;
CloudStorageAccount storageAccount = CloudStorageAccount .Parse(ConfigurationSettings .AppSettings["CloudStorage" ].ToString());
CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
//Get a reference to the container.
CloudBlobContainer container = blobClient.GetContainerReference("ContainerName" );
///////// Getting Blobs if's more than 5000 ///////////
ResultContinuation continuationToken = resultSegment.ContinuationToken;
//Check whether there are more results and list them in pages of 1000.
while (continuationToken != null )
{
resultSegment = container.ListBlobsSegmented(pagingCount, continuationToken, options);
foreach (var blobItem in resultSegment.Results)
{
//writing the blob name into the text file
Console .WriteLine(blobItem.Uri.Segments[2]);
}
//getting blob list count per Paging
Console .WriteLine(resultSegment.Results.Count());
//Console.ReadLine();
continuationToken = resultSegment.ContinuationToken;
//calling next set of blob list
resultSegment.GetNext();
}
//close the stream
tw.Close();
