L' System.Web.MimeMapping
a 3 versions - deux version 4.0 s (où l'un de ces est interne), puis une version 2.0 qui est aussi interne. Comme l'a souligné, il y a une version publique de la classe dans le Système.Web version 4.0 pour l' .NET 4.5 framework.
Pour RoadkillWiki j'ai fait une rétro-ingénierie pour enregistrer la peine de réfléchir à chaque fois, le Wiki du gestionnaire de fichier tente de l'utiliser IIS/applicationhost.config par défaut, puis passe à travers le MimeMapping classe:
private string GetMimeType(string fileExtension, ServerManager serverManager)
{
try
{
string mimeType = "text/plain";
Microsoft.Web.Administration.Configuration config = serverManager.GetApplicationHostConfiguration();
ConfigurationSection staticContentSection = config.GetSection("system.webServer/staticContent");
ConfigurationElementCollection mimemaps = staticContentSection.GetCollection();
ConfigurationElement element = mimemaps.FirstOrDefault(m => m.Attributes["fileExtension"].Value.ToString() == fileExtension);
if (element != null)
mimeType = element.Attributes["mimeType"].Value.ToString();
return mimeType;
}
catch (UnauthorizedAccessException)
{
// Shared hosting won't have access to the applicationhost.config file
return MimeMapping.GetMimeMapping("." +fileExtension);
}
}
Et MimeMapping:
public class MimeMapping
{
private static Dictionary<string, string> ExtensionMap = new Dictionary<string, string>();
static MimeMapping()
