Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment' 引发异常

Question

WPF 新手。当我单击 WPF 应用程序中的按钮时，我想将图片上传到 azure blob。我有以下代码 1- 打开文件对话框，2- GetContainer 类。 为什么这不起作用？ 私人无效btnUpload_Click（对象发送者，RoutedEventArgs e） {

        // Configure open file dialog box 
        Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();
        dlg.FileName = "Picture"; // Default file name 
        //dlg.DefaultExt = ".txt"; // Default file extension 
        dlg.Filter = "JPEG Files (*.jpeg)|*.jpeg|PNG Files (*.png)|*.png|JPG Files (*.jpg)|*.jpg|GIF Files (*.gif)|*.gif"; // Filter files by extension 

        // Show open file dialog box 
        Nullable<bool> result = dlg.ShowDialog();

        // Process open file dialog box results 
        if (result == true)
        {
            // Open document 
            string filename = dlg.FileName;//*********************ABOVE CODE OPENS FILES TO SELECT************************
        }

    }
             {
        string uniqueBlobName = Guid.NewGuid().ToString();

        // Retrieve storage account from connection string.
        CloudStorageAccount objStorage = CloudStorageAccount.Parse(RoleEnvironment.GetConfigurationSettingValue("DefaultEndpointsProtocol=https;AccountName=*********;AccountKey=************)

        // Create the blob client.
        CloudBlobClient objclient = objStorage.CreateCloudBlobClient();

        // Retrieve a reference to a container.
        CloudBlobContainer objContainer = objclient.GetContainerReference("rewardsimageblob");

        // Create the container if it doesn't already exist.
        objContainer.CreateIfNotExist();

        // Retrieve reference to a blob named "uniqueBlobName"
        CloudBlob blob = objContainer.GetBlobReference(uniqueBlobName);

        // Create or overwrite the "uniqueBlobName" blob with contents from a local file.
        using (var fileStream = System.IO.File.OpenRead(@"path\myfile"))
        {
            blob.UploadFromStream(fileStream);
        }        
}

}
