Upload a Single File to Blob Storage Azure

Question

How can I to Upload a file with C# ? I need to upload a file from a dialogWindow.

Answer 1

using Microsoft.WindowsAzure.Storage;
using Microsoft.WindowsAzure.Storage.Auth;
using Microsoft.WindowsAzure.Storage.Blob;    

// Retrieve storage account from connection string.
    CloudStorageAccount storageAccount = CloudStorageAccount.Parse("StorageKey");

// Create the blob client.
CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

// Retrieve reference to a previously created container.
CloudBlobContainer container = blobClient.GetContainerReference("mycontainer");

// Retrieve reference to a blob named "myblob".
CloudBlockBlob blockBlob = container.GetBlockBlobReference("myblob");

// Create or overwrite the "myblob" blob with contents from a local file.
using (var fileStream = System.IO.File.OpenRead(@"path\myfile"))
{
    blockBlob.UploadFromStream(fileStream);
}

Answer 2

Since WindowsAzure.Storage is legacy. With Microsoft.Azure.Storage.* we can use the following code to upload

  static async Task CreateBlob()
    {
        
        BlobServiceClient blobServiceClient = new BlobServiceClient(storageconnstring);
        
        BlobContainerClient containerClient = blobServiceClient.GetBlobContainerClient(containerName);
        
        BlobClient blobClient = containerClient.GetBlobClient(filename);

        
        using FileStream uploadFileStream = File.OpenRead(filepath);
        
        await blobClient.UploadAsync(uploadFileStream, true);
        uploadFileStream.Close();
    }
