在C中保存單個用戶設置＃

Question

我正在努力實現在我的.NET C＃應用程序中保存用戶設置，並且在一種情況下我只想保存一個設置。是否有可能做到這一點，或者是在一次保存所有用戶設置的標準我唯一的選擇：

Properties.Settings.Default.Save(); 

Answer 1

我更喜歡使用NINI，並存儲在某個地方XML配置文件中像Environment.SpecialFolder.ApplicationData。

可能不像.NET設置那麼簡單。無論如何，我從未真正使用過它們。

例如，我有以下課程。所有我需要做的是獲取或設置屬性，它們會自動加載/保存：

using Nini.Config; 

public class DbConfig : PropertyNotifierBase { 
    private static readonly string PROGRAM_NAME = "programname"; 
    private static readonly string CONFIG_NAME = "Database"; 

    private static DbConfig _instance = new DbConfig(); 

    public static DbConfig Instance { get { return (_instance); } } 

    private DbConfig() { 
     SetupPaths(); 
     Source = new XmlConfigSource(FullConfigFilename); 
     Source.AutoSave = true; 
     CreateSectionsIfNeeded(); 
    } 

    private void CreateSectionsIfNeeded() { 
     if (Source.Configs["Database"] == null) 
      Source.AddConfig("Database"); 
    } 

    private void SetupPaths() { 
     ConfigPath = DetermineConfigPath(); 
     ConfigFilename = String.Format("{0}.xml", CONFIG_NAME); 
     Directory.CreateDirectory(ConfigPath); 

     // Create an empty configuration file if it isn't there. 
     if (!File.Exists(FullConfigFilename)) 
      File.WriteAllText(FullConfigFilename, "<Nini>\n</Nini>\n"); 
    } 

    private IConfigSource Source { get; set; } 

    public String ConfigPath { get; private set; } 

    public String ConfigFilename { get; private set; } 

    public String FullConfigFilename { get { return (Path.Combine(ConfigPath, ConfigFilename)); } } 

    public String SqlServerInstance { 
     get { return (Source.Configs["Database"].GetString("SqlServerInstance", @"somedefaultconnection")); } 
     set { Source.Configs["Database"].Set("SqlServerInstance", value); NotifyPropertyChanged("SqlServerInstance"); } 
    } 

    public String SqlServerDatabase { 
     get { return (Source.Configs["Database"].GetString("SqlServerDatabase", "somedatabasename")); } 
     set { Source.Configs["Database"].Set("SqlServerDatabase", value); NotifyPropertyChanged("SqlServerDatabase"); } 
    } 

    public String SqlServerUsername { 
     get { return (Source.Configs["Database"].GetString("SqlServerUsername", "someusername")); } 
     set { Source.Configs["Database"].Set("SqlServerUsername", value); NotifyPropertyChanged("SqlServerUsername"); } 
    } 

    public String SqlServerPassword { 
     get { return (Source.Configs["Database"].GetString("SqlServerPassword", "somepassword")); } 
     set { Source.Configs["Database"].Set("SqlServerPassword", value); NotifyPropertyChanged("SqlServerPassword"); } 
    } 

    private string DetermineConfigPath() { 
     String filename = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData); 
     filename += Path.DirectorySeparatorChar + PROGRAM_NAME; 
     return (filename); 
    } 
}
