将一个 Azure blob 复制到 Azure Storage Client 2.0 中的另一个 blob [英] Copying one Azure blob to another blob in Azure Storage Client 2.0

问题描述

在旧的 1.7 存储客户端中有一个 CloudBlob.CopyFromBlob(otherBlob) 方法，但它似乎没有出现在 2.0 版本中.复制 blob 的推荐最佳做法是什么?我确实看到了 iCloudBlob.BeginStartCopyFromBlob 方法.如果这是合适的方法，我该如何使用它?

In the old 1.7 storage client there was a CloudBlob.CopyFromBlob(otherBlob) method, but it does not seem to be present in the 2.0 version. What is the recommended best practice for copying blobs? I do see a ICloudBlob.BeginStartCopyFromBlob method. If that is the appropriate method, how do I use it?

推荐答案

Gaurav Mantri 写了一系列文章在 2.0 版的 Azure 存储上.我从他的博客文章 Storage Client Library 2.0 – 为 Blob Copy 迁移 Blob 存储代码

Gaurav Mantri has written a series of articles on Azure Storage on version 2.0. I have taken this code extract from his blog post of Storage Client Library 2.0 – Migrating Blob Storage Code for Blob Copy

CloudStorageAccount storageAccount = new CloudStorageAccount(new StorageCredentials(accountName, accountKey), true);
CloudBlobClient cloudBlobClient = storageAccount.CreateCloudBlobClient();
CloudBlobContainer sourceContainer = cloudBlobClient.GetContainerReference(containerName);
CloudBlobContainer targetContainer = cloudBlobClient.GetContainerReference(targetContainerName);
string blobName = "<Blob Name e.g. myblob.txt>";
CloudBlockBlob sourceBlob = sourceContainer.GetBlockBlobReference(blobName);
CloudBlockBlob targetBlob = targetContainer.GetBlockBlobReference(blobName);
targetBlob.StartCopyFromBlob(sourceBlob);
