       byte[] buffer = new byte[fs.Length]; 
       fs.Read(buffer, 0, buffer.Length);

Veuillez fournir une solution correcte Pourquoi nous ne pouvons pas télécharger plus de taille de fichier. pour ce que nous devons faire?

Answer 1

Je pense que vous devez changer la taille de téléchargement par défaut dans votre webconfig

Vous aimez cette

<configuration> 
    <system.web> 
    <httpRuntime maxRequestLength="size in kbs" /> 
    </system.web> 
</configuration> 

La valeur par défaut est 4096 (= 4 Mo).
