これに近いすべての投稿を読んだ後、私はまだ解決策を見つけられません.
私が見つけた最も近い応答は ここにあります
ただし、これらの投稿の 2 つの点は当てはまりません。1. ほとんどの場合に確実に機能するコード例を使用しています。2. .NET クライアント プロファイルを使用する必要があるため、Azure StorageClient 単純化機能にアクセスできません。3. 私が見ないのはおそらくばかげたエラーです :-)
呼び出しは次のとおりです。
// Create Blob
// using REST: http://msdn.microsoft.com/en-us/library/windowsazure/dd135733.aspx
BlobHelper blobHelper = new BlobHelper(_storageAccountName, _storageKey);
Console.WriteLine("Create container...");
if (!blobHelper.CreateContainer("mytestcontainer")) //(blobInfo.ContainerName))
{
Console.WriteLine("REST: Create Blob Failed");
}
そして、これがワイヤーリクエストです（フィドラー）：
PUT /devstoreaccount1/mytestcontainer?restype=container HTTP/1.1
x-ms-date: Mon, 25 Jun 2012 16:54:01 GMT
x-ms-version: 2009-09-19
Authorization: SharedKey devstoreaccount1:REpHdtTSQrwGtXuEbLJmRQdpe/j2l5icmGUeFkQ09jw=
Host: 127.0.0.1:10000
Content-Length: 0
Connection: Keep-Alive
ライブの Azure Storage を使用しても、Developer Storage を使用しても、同じことが起こります。
ワイヤー応答は次のとおりです。

言うまでもなく、これは私を夢中にさせるので、どんなヒントでも感謝します.
