Problème avec le téléchargement de nombreux fichiers de WCF

Question

J'ai un problème avec le service WCF. Quand je télécharge 2 fichiers tout fonctionne bien (moins de 1 minute), mais quand j'essaye de télécharger plus de 3 fichiers, il y a quelque chose qui va mal. J'attends et j'attends et rien:/Chaque fichier a environ 1 Mo.

Dictionary<FileIdentifier, Stream> data = new Dictionary<FileIdentifier, Stream>(); 

foreach (string path in paths) 
{ 

    using (var client = new ServiceClient()) 
    { 
     var stream = client.GetFile(path); 

     data[fileIdentifier] = stream; 
    } 

} 

Méthode au service WCF:

public Stream GetFile(string path) 
     { 
      FileStream fs = new FileStream(stream, FileMode.Open); 
      fs.Close(); 
      return fs; 

     }

Answer 1

Vous ne devez pas fermer le flux côté service.

Voici comment vous faire:

1. flux ouvert sur le service
2. flux de retour au client
3. Lire le flux sur le client
4. Fermez le flux sur le client
5. WCF prendra soin de fermer le flux de service pour vous

Answer 2

au lieu de retourner un ruisseau, lire le flux dans un tableau d'octets, puis retourne le tableau d'octets .
