I made this method some time ago:

public static string GetMimeType(string fileName)
{
    string mimeType = "application/unknown";
    string ext = Path.GetExtension(fileName).ToLower();
    Microsoft.Win32.RegistryKey regKey = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(ext); // henter info fra windows registry
    if (regKey != null && regKey.GetValue("Content Type") != null)
    {
        mimeType = regKey.GetValue("Content Type").ToString();
    }
    else if (ext == ".png") // a couple of extra info, due to missing information on the server
    {
        mimeType = "image/png";
    }
    else if (ext == ".flv")
    {
        mimeType = "video/x-flv";
    }
    return mimeType;
}

You can use that to set the mimetype, like this:

Response.ContentType = GetMimeType(@CompletePhysicalPath);
