.NET için Microsoft Azure Yapılandırma Yöneticisi Kitaplığı, yapılandırma dosyasından bağlantı dizesini ayrıştırmak için bir sınıf sağlar. Cloudconfigurationmanager sınıfı yapılandırma ayarlarını ayrıştırır. Masaüstünde, bir mobil cihazda, bir Azure sanal makinesinde veya Azure bulut hizmetinde çalışan istemci uygulamalarına yönelik ayarları ayrıştırır.

Pakete başvurmak için CloudConfigurationManager aşağıdaki using yönergeleri ekleyin:

using Microsoft.Azure; //Namespace for CloudConfigurationManager
using Microsoft.Azure.Storage;

Burada, yapılandırma dosyasından bir bağlantı dizesinin nasıl alındığını gösteren bir örnek bulunmaktadır:

// Parse the connection string and return a reference to the storage account.
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
    CloudConfigurationManager.GetSetting("StorageConnectionString"));

Azure Yapılandırma Yöneticisi'ni kullanmak isteğe bağlıdır. .NET Framework ConfigurationManager sınıfıgıbı bir API de kullanabilirsiniz.

Aşağıdaki yöntem, zaten yoksa bir dosya paylaşma oluşturur. Yöntemi bir bağlantı dizesinden bir parça eClient nesnesi oluşturarak başlar. Örnek daha sonra daha önce oluşturduğumuz bir dosyayı indirmeye çalışır. Bu yöntemi kaynağından çağırın Main() .

//-------------------------------------------------

    ShareClient share = new ShareClient(connectionString, shareName);

    // Create the share if it doesn't already exist
    await share.CreateIfNotExistsAsync();

    // Ensure that the share exists
    if (await share.ExistsAsync())

Sonra, Main() bağlantı dizesini almak için yukarıda gösterilen koddan sonra yöntemine aşağıdaki içeriği ekleyin. Bu kod, daha önce oluşturduğumuz dosyaya bir başvuru alır ve içeriğini çıkarır.

Paylaşılan erişim imzalarını yönetmek için, bir dosya paylaşımında depolanan erişim ilkesi de oluşturabilirsiniz. Güvenlik açığı varsa SAS 'yi iptal etmenizi sağladığından, depolanan bir erişim ilkesi oluşturmanızı öneririz. Aşağıdaki örnek, bir paylaşımda depolanan erişim ilkesi oluşturur.

İlk olarak, aşağıdaki using yönergeleri, yukarıdaki eklendikleriyle birlikte program. cs dosyanıza ekleyin:

using Microsoft.Azure.Storage.File.Protocol;
using Microsoft.Azure.Storage.Shared.Protocol;

Azure Blobları, Azure tabloları ve Azure kuyrukları ServiceProperties ad alanındaki paylaşılan türünü kullanmasına rağmen Microsoft.Azure.Storage.Shared.Protocol , Azure dosyaları FileServiceProperties ad alanındaki türü kendi türünü kullanır Microsoft.Azure.Storage.File.Protocol . Kodunuzda her iki ad alanına da başvurmanız gerekir, ancak aşağıdaki kodun derlenmesi için.

// Parse your storage connection string from your application's configuration file.
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
        Microsoft.Azure.CloudConfigurationManager.GetSetting("StorageConnectionString"));
// Create the File service client.
CloudFileClient fileClient = storageAccount.CreateCloudFileClient();

// Set metrics properties for File service.
// Note that the File service currently uses its own service properties type,
// available in the Microsoft.Azure.Storage.File.Protocol namespace.
fileClient.SetServiceProperties(new FileServiceProperties()
{
    // Set hour metrics
    HourMetrics = new MetricsProperties()
    {
        MetricsLevel = MetricsLevel.ServiceAndApi,
        RetentionDays = 14,
        Version = "1.0"
    },
    // Set minute metrics
    MinuteMetrics = new MetricsProperties()
    {
        MetricsLevel = MetricsLevel.ServiceAndApi,
        RetentionDays = 7,
        Version = "1.0"
    }
});

// Read the metrics properties we just set.
FileServiceProperties serviceProperties = fileClient.GetServiceProperties();
Console.WriteLine("Hour metrics:");
Console.WriteLine(serviceProperties.HourMetrics.MetricsLevel);
Console.WriteLine(serviceProperties.HourMetrics.RetentionDays);
Console.WriteLine(serviceProperties.HourMetrics.Version);
Console.WriteLine();
Console.WriteLine("Minute metrics:");
Console.WriteLine(serviceProperties.MinuteMetrics.MetricsLevel);
Console.WriteLine(serviceProperties.MinuteMetrics.RetentionDays);
Console.WriteLine(serviceProperties.MinuteMetrics.Version);
