我找到了答案！

            byte[] dataKey = File.ReadAllBytes(fileName);

        Org.BouncyCastle.Crypto.AsymmetricKeyParameter asp =
            Org.BouncyCastle.Security.PrivateKeyFactory.DecryptKey(pass.ToCharArray(), dataKey);

        MemoryStream ms = new MemoryStream();
        TextWriter writer = new StreamWriter(ms);
        System.IO.StringWriter stWrite = new System.IO.StringWriter();
        Org.BouncyCastle.OpenSsl.PemWriter pmw = new PemWriter(stWrite);
        pmw.WriteObject(asp);
        stWrite.Close();
        return stWrite.ToString();
