Azure存储容器大小

Question

如何在Azure存储中获取容器大小？我通过C#API访问Azure存储:

var account = CloudStorageAccount.Parse(ConfigurationManager.AppSettings["AzureStoragePrimary"]);
var client = account.CreateCloudBlobClient();
var container = client.GetContainerReference("myContainer");

Answer 1

CloudStorageAccount cloudStorageAccount = CloudStorageAccount.Parse(ConfigurationManager.AppSettings["AzureStoragePrimary"]);
CloudBlobClient blobClient = account.CreateCloudBlobClient();
CloudBlobContainer blobContainer = blobClient.GetContainerReference("myContainer");
int fileSize = 0;
foreach (var blobItem in blobContainer.ListBlobs())
{
    fileSize += blobItem.Properties.Length;
} 

fileSize 包含容器的大小,即包含的blob(文件)的总大小.

一种可能更完整的方法.关键的区别是listblobs()调用中的第二个参数,它强制执行一个平面列表:

public class StorageReport
{
    public int FileCount { get; set; }
    public int DirectoryCount { get; set; }
    public long TotalBytes { get; set; }
}

//embdeded in some method
StorageReport report = new StorageReport() { 
    FileCount = 0,
    DirectoryCount = 0,
    TotalBytes = 0
};


foreach (IListBlobItem blobItem in container.ListBlobs(null, true, BlobListingDetails.None))
{
    if (blobItem is CloudBlockBlob)
    {
        CloudBlockBlob blob = blobItem as CloudBlockBlob;
        report.FileCount++;
        report.TotalBytes += blob.Properties.Length;
    }
    else if (blobItem is CloudPageBlob)
    {
        CloudPageBlob pageBlob = blobItem as CloudPageBlob;

        report.FileCount++;
        report.TotalBytes += pageBlob.Properties.Length;
    }
    else if (blobItem is CloudBlobDirectory)
    {
        CloudBlobDirectory directory = blobItem as CloudBlobDirectory;

        report.DirectoryCount++;
    }                        
}

我已将Windows Azure SDK中的Microsoft.WindowsAzure.StorageClient.dll 1.1.0.0 更新为Windows Azure Storage NuGet包中的Microsoft.WindowsAzure.Storage.dll 2.0.0.0,现在可以正常使用.

long size = 0;
var list = container.ListBlobs();
foreach (CloudBlockBlob blob in list) {
    size += blob.Properties.Length;
}
