我嘗試將 2GB 檔案上傳到 Azure 存盤，但我的代碼失敗并且出現例外。對于較小的檔案，它作業正常。如何更改超時和檔案大小限制？我在 .NET Core 上使用 Azure.Storage.Blobs 版本 12.10.0。
我的代碼：
public FileRepository(AppSettings appSettings)
{
var blobServiceClient = new BlobServiceClient(appSettings.StorageConnectionString);
var containers = blobServiceClient.GetBlobContainers();
if (!containers.Any(x => x.Name == containerName))
{
blobServiceClient.CreateBlobContainer(containerName);
}
_blobContainerClient = blobServiceClient.GetBlobContainerClient(containerName);
}
public async Task<string> Upload(string fileName, Stream content)
{
var blobName = $"{Guid.NewGuid()}/{fileName}";
await _blobContainerClient.UploadBlobAsync(blobName, content);
return blobName;
}
我有例外：
System.AggregateException
HResult=0x80131500
Message=Retry failed after 6 tries. (The operation was canceled.) (The operation was canceled.) (The operation was canceled.) (The operation was canceled.) (The operation was canceled.) (The operation was canceled.)

我認為使用BlobContainerClient.
您將需要使用類中的UploadAsync方法BlobClient并在BlobUploadOptions.TransferOptions.
如果您想對上傳程序進行更細粒度的控制，則需要在特定 Blob 客戶端中使用上傳方法。例如，如果您要上傳塊 blob，則可以使用BlockBlobClient.StageBlockAsync和BlockBlobClient.CommitBlockListAsync。

您可以將檔案拆分 chunks/blocks 為客戶端。然后發送許多小塊 100 MB。
將檔案拆分為更小的塊，如果您使用的是像代碼這樣的Stream只會讀取一定數量的位元組并處理它們直到完成。
有關更多詳細資訊，請參閱實作檔案分塊、分塊上傳檔案 和放置 Blob。
