Check Container Exists In Azure Blob Storage in C#.Net

In this article i am going to explain about How to Check Container Exists In Azure Blob Storage in C#.Net .There is no predefined method exists in the .Net Library to check whether the specific container exists or not in the blob storage. But we can check the container existence using Get Blob Properties, which does a HEAD request against the blob and returns 404 error if the container doesn’t exists.

In my previous article i have explained about Azure Blob Storage Create Container – C#.Net,VB.Net, Asp.Net GridView Sorting Example Using C#.Net & VB.Net, Convert Dataset Datatable To Json Data Array, Show Tooltip On Mouse Hover In Gridview, SQL Script To Drop Multiple Tables,Procedures At Once and many articles in C#.Net,ASP.Net,VB.Net,Grid View,Javascript,jQuery,Azure Blob Storage and many other topics.

Create a console application and include the System.Configuration,Microsoft.WindowsAzure and Microsoft.WindowsAzure.StorageClient dlls to your project. And then include the below dlls in your project.


using System;

Add the below details in the configuration file.

  <add name=StorageAccount connectionString=DefaultEndpointsProtocol=https;AccountName=youraccoutname;AccountKey=youraccountkey />
  <add key=containername value=samplecontainer/>

Now the below code is used to check the existence of the container in blobstorage.


class Program
    static void Main(string[] args)
        //Reading connection string from app.config.
        stringstorageConnectionString = ConfigurationManager.ConnectionStrings[“StorageAccount”].ConnectionString;
        //Reading container name from app.config.
        string containerName =
        //Connecting Cloud storage account
        CloudStorageAccount Account =
        //Creating BlobClient using the above credentials
        CloudBlobClientBlobClient = Account.CreateCloudBlobClient();
        Console.WriteLine(“Checking container existence..”);
        CloudBlobContainercontainer =
            //Fetches attributes of container
            Console.WriteLine(“Container exists..”);
        catch (StorageClientException e)
            //throws error if the specified container not exists
            if (e.ErrorCode == StorageErrorCode.ResourceNotFound)
                Console.WriteLine(“Container not exists..”);
                // other exceptions
                Console.WriteLine(“Errr..: “ + e.Message);

The console output is shown below.
