如何在Asp.Net Core中将文件上传到Azure Blob？

Question

我尝试使用以下代码将文件上传到我的azure blob中

  public async void UploadSync(IEnumerable<IFormFile> files, string path)
        {
            string MyPath = path.Replace("https://browsercontent.blob.core.windows.net/blob1/", "");

            try
            {
                foreach (var file in files)
                {
                    var newBlob = container.GetBlockBlobReference(MyPath);
                    await newBlob.UploadFromFileAsync(@"C:\Users\joy\Downloads\" + file.FileName);

                }
            }
            catch (Exception ex)
            { throw ex;}

        }

实际上，我已经上传了jpg文件，但它以“应用程序/八位字节码”类型上传。 怎么解决呢？

我的情况是上传文件时，Windows资源管理器将打开以选择要上传的文件。 因此，如果我们提供的静态路径如下所示，

newBlob.UploadFromFileAsync（ @“ C：\\ Users \\ joy \\ Downloads \\” + file.FileName ）;

它不适用于申请。 如何更改此代码以从各个位置上传文件？

尝试使用UploadFromStream，让我知道结果

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

// 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);
}
