在Azure blob存储中设置和检索blob的元数据

我只是想知道是否可以设置和检索元数据 关于存储在该容器内目录中的blob?

是的,你当然可以这样做。请参见下面的示例代码:

        const string ConnectionString = "DefaultEndpointsProtocol=https;AccountName=account-name;AccountKey=account-key";
        CloudStorageAccount storageAccount = CloudStorageAccount.Parse(ConnectionString);

        //Create the service client object for credentialed access to the Blob service.
        CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

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

        CloudBlockBlob blob = container.GetBlockBlobReference("images/logo.png");
        blob.FetchAttributes();//Gets the properties & metadata for the blob.
        blob.Metadata.Add("Key", "Value");
        blob.SetMetadata();//Saves the metadata.
