实现一个简易的记住密码功能

由于最近一个项目未曾使用数据库，所以在记住密码的时候，只能保存数据到本地，

/// <summary>
/// 保存在本地的登录用户
/// 在不启用数据库的情况下，可以对外使用本地数据
/// </summary>
public class LoginInfoLocation
{
    public const string LoginPath = "E://Datas//loginInfo.xml";

}
 public class LoginDto
 {
     public string UserName { get; set; }
     public string Password { get; set; }
     public bool IsRemember { get; set; }
 }

项目使用了Stylet框架

  public class LoginViewModel : ViewModelBase
 {
     private LoginDto _loginDto;

     public LoginDto LoginDto
     {
         get => _loginDto ?? (_loginDto = new LoginDto());
         set => SetAndNotify(ref _loginDto, value);
     }
     private IWriteService _writeService;
     private IReadService _readService;

     public LoginViewModel(IWriteService writeService,IReadService readService)
     {
         _writeService = writeService;
         _readService = readService;
     }

     public void ExecuteLogin() { }

     public void ExecuteCancel()
     {
         Application.Current.Shutdown();
     }

     public void ExecuteChanged()
     {
         var info = XmlFolderHelper.SerializeXML<LoginDto>(LoginDto);
         _writeService.WriteString(LoginInfoLocation.LoginPath, info);
     }

     protected override void OnActivate()
     {
         base.OnActivate();
         try
         {
             var xmlData = _readService.Read(LoginInfoLocation.LoginPath);   
             var doc = XDocument.Parse(xmlData);
             List<string> result = doc.Root.Elements().Select(node => node.Value).ToList();
             var isRememberValue = doc.Element("LoginDto").Element("IsRemember").Value;
             // 将字符串转换为bool类型
             if (bool.TryParse(isRememberValue, out bool isRemember))
             {
                 if (isRemember&& result.Count==3)
                 {
                     LoginDto = XmlFolderHelper.Deserialize<LoginDto>(xmlData);
                 }
                 else
                 {
                     LoginDto = null;
                 }
             }
         }
         catch (Exception ex)
         {
             MessageBox.Show(ex.Message);
         }
     }
 }
