I want to read files from an azure blob storage (the files inside the folder), the blob storage contains many folders. I want to read my folder 'blobstorage' ,it contains many JSON files performing .read to each file and some manipulations. I tried many code that did not work:
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(connectionString);
CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
CloudBlobContainer container = blobClient.GetContainerReference($"blobstorage");
The above code uses 'Microsoft.WindowsAzure.Storage' nuget package. This code is not working as expected. In many questions and answers found in stack overflow I found that most of them are outdated and does not work. Note: if any nuget mention that also bcs they are many packages
I found the solution in this post and worked perfectly for me. You just have to read it as a normal stream after the download.
BlobServiceClient blobServiceClient = new BlobServiceClient("connectionString");
BlobContainerClient containerClient = blobServiceClient.GetBlobContainerClient("containerName");
BlobClient blobClient = containerClient.GetBlobClient("blobName.csv");
if (await blobClient.ExistsAsync())
{
var response = await blobClient.DownloadAsync();
using (var streamReader= new StreamReader(response.Value.Content))
{
while (!streamReader.EndOfStream)
{
var line = await streamReader.ReadLineAsync();
Console.WriteLine(line);
}
}
}
