How can I get MIME type from the extension of a file

Question

I know in web form there exists a ContentType property to get MIME type of a file, but how can I get it in the windows form? There are too many types in the MIME standard, I don't want to realize it by myself. ^_^ Thanks.

Hi.. Use the Following Code to Get the MIME Type from the Win Form using System; using System.Security; using System.Security.Permissions; using Microsoft.Win32; using System.IO; public class GetMime { public string GetMIMEType(string filepath) { RegistryPermission regPerm = new RegistryPermission(RegistryPermissionAccess.ReadHKEY_CLASSES_ROOT); RegistryKey classesRoot = Registry.ClassesRoot; FileInfo fi = new FileInfo(filepath); string dotExt = fi.Extension; RegistryKey typeKey = classesRoot.OpenSubKey(MIME\Database\Content Type); foreach (string keyn in typeKey.GetSubKeyNames()) { RegistryKey curKey = classesRoot.OpenSubKey(MIME\Database\Content Type\ + keyn); if (((curKey.GetValue(Extension)+).ToLower()) == dotExt.ToLower()) return keyn; } return Not Found; } public static void Main() { GetMime obj = new GetMime(); Console.WriteLine(obj.GetMIMEType(Mani.gif)); Console.WriteLine(obj.GetMIMEType(Mani.xml)); Console.WriteLine(obj.GetMIMEType(Mani.jpg)); Console.WriteLine(obj.GetMIMEType(Mani.txt)); Console.WriteLine(obj.GetMIMEType(Mani.css)); } } -Manivannan D
