Usage in csharp code

var provider = StreamStorage.StreamStorageServiceFactory.Create().Provider;
// define object name
string objectName = "client_1/" + System.Guid.NewGuid().ToString("D") + ".txt";

// check object is exists or not
bool objExists = provider.ObjectExists(objectName);

// save object (if exists, then override it)
using (System.IO.Stream ms = new System.IO.MemoryStream())
{
    byte[] buffer = System.Text.Encoding.UTF8.GetBytes("Hello, my friend!");
    ms.Write(buffer, 0, buffer.Length);
    ms.Position = 0;
    provider.PutObject(objectName, ms, true);
    ms.Close();
}

// save object (if exists, then override it), fill with metadata
StreamStorage.ObjectMetadata metadata = new StreamStorage.ObjectMetadata metadata();
metadata.ContentDisposition = "attachment;filename=FriendlyFileName.txt";
using (System.IO.Stream ms = new System.IO.MemoryStream())
{
    byte[] buffer = System.Text.Encoding.UTF8.GetBytes("Hello, my friend!");
    ms.Write(buffer, 0, buffer.Length);
    ms.Position = 0;
    provider.PutObject(objectName, ms, true, metadata);
    ms.Close();
}

// get object
using (var obj = provider.GetObject(objectName))
{
    var content = obj.Content;
    var currentMetaData = obj.ObjectMetadata;
    // do it here
}

// get object metadata
metadata = provider.GetObjectMetadata(objectName);

// delete object
provider.DeleteObject(objectName);

// delete it and sub objects behind that.
provider.DeleteObject("client_1");
