将url从utf-8编码重新编码为iso-8859-1编码

file://development/H%C3%A5ndplukket.doc

变成

file://development/H%e5ndplukket.doc

我有以下有效的代码:

public string ReEncodeUrl(string url)
{
    Encoding enc = Encoding.GetEncoding("iso-8859-1");
    string[] parts = url.Split('/');
    for (int i = 1; i < parts.Length; i++)
    {
        parts[i] = HttpUtility.UrlDecode(parts[i]); // Decode to string
        parts[i] = HttpUtility.UrlEncode(parts[i], enc); // Re-encode to latin1
        parts[i] = parts[i].Replace('+', ' '); // Change + to [space]
    }
    return string.Join("/", parts);
}

有没有更干净的方法?
