我的客户需要一个 com interop dll 来保存和删除存储中的 Windows Azure Blob(他使用 VB6 并且不能直接调用存储)。我以前多次写过这样的 ComInterop DLL,但是现在,当从 VB6 应用程序调用 DLL 时,他得到了一个运行时文件未找到异常 80070002:
'无法加载文件或程序集'Microsoft.WindowsAzure.Storage,Version=2.0.0.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35'或其依赖项之一。
有任何想法吗?
这里有一个小代码片段:
[Serializable]
[Guid("...")]
[ClassInterface(ClassInterfaceType.AutoDual)]
[ComSourceInterfaces(typeof(IBlobOperations))]
[ComVisible(true)]
[ProgId("...")]
public class BlobOperations
{
#region (Aufrufbare Funktionen) ---------------------------------------
private const string BlobConnection =
"DefaultEndpointsProtocol=https;AccountName=...;AccountKey=...";
private const string Container = "...";
public void BlobChange(string fileLocation, string blobName)
{
try
{
var storageAccount = CloudStorageAccount.Parse(BlobConnection);
// Create the blob client.
var blobClient = storageAccount.CreateCloudBlobClient();
// Retrieve reference to a previously created container.
var container = blobClient.GetContainerReference(Container);
// Retrieve reference to a blob named "myblob".
var blockBlob = container.GetBlockBlobReference(blobName);
// Create or overwrite the "myblob" blob with contents from a local file.
using (var fileStream = System.IO.File.OpenRead(fileLocation))
{
blockBlob.UploadFromStream(fileStream);
}
}
catch (Exception e)
{
...
}
}
