Dans une application C# .Net MVC2, nous avons une fonction simple pour obtenir l'identifiant du processeur dans le cadre d'un schéma d'identification du serveur web. La partie pertinente est:ManagementObjectRecherche out of memory excepiton
using (ManagementObjectSearcher searcher = new ManagementObjectSearcher("select ProcessorId from Win32_Processor"))
{
foreach (ManagementObject share in searcher.Get())
{
foreach (PropertyData PC in share.Properties)
{
return PC.Value.ToString();
}
}
}
il travaille bien dans dev et sur un certain nombre de serveurs Web exécutant IIS et Cassini. Toutefois, lors de la dernière installation sur un ordinateur Server 2008, il lance une exception Out of Memory lors du premier appel pour obtenir l'ID du processeur. Tout conseil sur une cause possible ou un meilleur moyen d'atteindre ce qui précède.
Merci beaucoup
