Question

我想在容器中列出blob。对于桌面应用程序，Azure Storage SDK提供以下方法：

CloudBlobContainer container = blobClient.GetContainerReference("myBlob"); 
container.ListBlobs();

但是，使用WinRT library方法不存在（可能是由于其阻塞性质）。我该怎么用？

Answer 1

您需要在blob容器上使用ListBlobsSegmentedAsync函数来获取blob列表。请参阅以下代码：

    CloudStorageAccount account = new CloudStorageAccount(new StorageCredentials("accountname", "accountkey"), true);
    var client = account.CreateCloudBlobClient();
    var container = client.GetContainerReference("containername");
    BlobContinuationToken continuationToken = null;
    string prefix = null;
    bool useFlatBlobListing = true;
    BlobListingDetails blobListingDetails = BlobListingDetails.All;
    int maxBlobsPerRequest = 10;
    List<IListBlobItem> blobs = new List<IListBlobItem>();
    do
    {
        var listingResult = await container.ListBlobsSegmentedAsync(prefix, useFlatBlobListing, blobListingDetails, maxBlobsPerRequest, continuationToken, null, null);
        continuationToken = listingResult.ContinuationToken;
        blobs.AddRange(listingResult.Results);
    }
    while (continuationToken != null);

修改代码以支持Azure 2.2

CloudStorageAccount account = new CloudStorageAccount(new StorageCredentials("accountname", "accountkey"), true);
var client = account.CreateCloudBlobClient();
var container = client.GetContainerReference("containername");
BlobContinuationToken continuationToken = null;
string prefix = null;
bool useFlatBlobListing = true;
BlobListingDetails blobListingDetails = BlobListingDetails.All;
int maxBlobsPerRequest = 10;
List<IListBlobItem> blobs = new List<IListBlobItem>();
do
{
    var listingResult = await container.ListBlobsSegmentedAsync(prefix, useFlatBlobListing, blobListingDetails, maxBlobsPerRequest, continuationToken, null, null);
    continuationToken = **listingResult.Result.ContinuationToken;**
    blobs.AddRange(**listingResult.Result.Results**);
}
while (continuationToken != null);
