编码＆amp;在WPF C＃中解码字符串

Question

我正在尝试编码＆amp;解码保存到WPF应用程序的.ini设置文件的字符串。

编码＆amp;解码类

class EncryptDecrypt
{

    public static string Base64Encode(string plainText)
    {
        var plainTextBytes = System.Text.Encoding.UTF8.GetBytes(plainText);
        return System.Convert.ToBase64String(plainTextBytes);
    }

    public static string Base64Decode(string base64EncodedData)
    {
        var base64EncodedBytes = System.Convert.FromBase64String(base64EncodedData);
        return System.Text.Encoding.UTF8.GetString(base64EncodedBytes);
    }

}

编码似乎正确地保存到.ini文件中，但是从.ini文件中解码条目似乎输出了不正确的字符串，如下所示;

来自密码字段的

编码工作正常（在save_click上）

inif.Write("APISettings", "HashKey", EncryptDecrypt.Base64Encode(hash_key.Password.ToString()));

但是，重新加载app然后导航到相同的字段/表单解码不正确输出条目（因为它用于检查页面的http状态）..

hash_key.Password = EncryptDecrypt.Base64Decode(inif.Read("APISettings", "HashKey"));

我可以看到输出的字符串是奇怪的翼状字符。

更新

解决方法是保存到xml文件，而不是保存到.ini文件，见下文;

        private void Save_Click(object sender, RoutedEventArgs e)
    {

        //Settings Data
        string appfolder = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
        string ApplicationPath = System.IO.Path.Combine(appfolder, "MyApp/Application");
        if (!Directory.Exists(ApplicationPath)) Directory.CreateDirectory(ApplicationPath);

        //Encryption

        if (!System.IO.File.Exists(ApplicationPath + @"\credentials.xml"))
        {
            XmlDocument doc = new XmlDocument();
            //(1) the xml declaration is recommended, but not mandatory
            XmlDeclaration xmlDeclaration = doc.CreateXmlDeclaration("1.0", "UTF-8", null);
            XmlElement root = doc.DocumentElement;
            doc.InsertBefore(xmlDeclaration, root);

            //(2) string.Empty makes cleaner code
            XmlElement elementNode = doc.CreateElement(string.Empty, "Credentials", string.Empty);
            doc.AppendChild(elementNode);

            //Base URL

            elementNodeHashKey.InnerText = EncryptDecrypt.Base64Encode(hash_key.Password.ToString());

            XmlElement elementNodeUpdated = doc.CreateElement(string.Empty, "Updated", string.Empty);
            elementNode.AppendChild(elementNodeUpdated);
            elementNodeUpdated.InnerText = DateTime.Now.ToString();

            doc.Save(ApplicationPath + @"\credentials.xml");

        }else{
