推荐答案

使用下面的代码：

use this below code :

// Retrieve reference to a blob named "photo1.jpg".
CloudBlockBlob blockBlob = container.GetBlockBlobReference("photo1.jpg");

如果没有，那么列出内容循环结束它找到你的相关文件名！

if not then list out the content loop over it to find u r relevant file name !

// Retrieve storage account from connection string.
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
    CloudConfigurationManager.GetSetting("StorageConnectionString"));

// Create the blob client. 
CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

// Retrieve reference to a previously created container.
CloudBlobContainer container = blobClient.GetContainerReference("photos");

// Loop over items within the container and output the length and URI.
foreach (IListBlobItem item in container.ListBlobs(null, false))
{
    if (item.GetType() == typeof(CloudBlockBlob))
    {
        CloudBlockBlob blob = (CloudBlockBlob)item;

        Console.WriteLine("Block blob of length {0}: {1}", blob.Properties.Length, blob.Uri);

    }
    else if (item.GetType() == typeof(CloudPageBlob))
    {
        CloudPageBlob pageBlob = (CloudPageBlob)item;

        Console.WriteLine("Page blob of length {0}: {1}", pageBlob.Properties.Length, pageBlob.Uri);

    }
    else if (item.GetType() == typeof(CloudBlobDirectory))
    {
        CloudBlobDirectory directory = (CloudBlobDirectory)item;

        Console.WriteLine("Directory: {0}", directory.Uri);
    }
}
