Azure Blob：CreateCloudBlobClient' 不是“CloudStorageAccount”的成员

Question

我将我的网络应用程序从 .Net 4.0 升级到了 .Net 4.5.2，但出现了一个我找不到解决方案的错误。它在与 Azure Blob 存储的任何接口期间。我删除了所有 NuGet 包并在 4.5.2 下再次添加它们。错误信息是：

错误 BC30456“CreateCloudBlobClient”不是“CloudStorageAccount”的成员。

进口：

Imports Microsoft.WindowsAzure
Imports Microsoft.WindowsAzure.Storage.Blob

Imports System.IO
Imports System.Data.SqlClient   

代码：

 Private _Account As CloudStorageAccount
Private _ImageContainerName As String = ""
Private _ConnectionString As String = ""

Public Sub New(storageEndpoint As String, imageContainerName As String, Optional ByVal connStr As String = "")
    _Account = CloudStorageAccount.Parse(storageEndpoint)
    _ImageContainerName = imageContainerName
    _ConnectionString = connStr
End Sub

Public ReadOnly Property Account As CloudStorageAccount
    Get
        Return _Account
    End Get
End Property

Public ReadOnly Property ImageContainerName As String
    Get
        Return _ImageContainerName
    End Get
End Property

Public Function GetImageFromStore(ByVal imageKey As String) As IO.Stream
    Dim blobStorage As CloudBlobClient = _Account.CreateCloudBlobClient


    Dim container As CloudBlobContainer = blobStorage.GetContainerReference(Me.ImageContainerName)
    If Not container.Exists Then
        container.CreateIfNotExists()
        container.SetPermissions(New BlobContainerPermissions With {.PublicAccess = BlobContainerPublicAccessType.Off})
    End If

    Dim blob As CloudBlockBlob = container.GetBlockBlobReference(imageKey)

    Dim stream As New MemoryStream()
    'Added 11/21/2012 because the pages were erroring out when the image wasn't found in the blob.  
    If blob.Exists Then
        blob.DownloadToStream(stream)
        stream.Position = 0
    End If

    Return stream
End Function

错误出现在这一行：

DIm blobStorage As CloudBlobClient = _Account.CreateCloudBlobClient

我使用 WindowsAzure.Storage V8.3.0 测试了 .Net 4.5.2。一切正常。将您的代码与我的代码进行比较后，我发现您遗漏了一条导入语句，如下所示。

Imports Microsoft.WindowsAzure.Storage
