使用.ini文件方便地管理WindowsForm中控件的值或状态

public int ReadInt(string section, string name, int def)
public string ReadString(string section, string name, string def = "")
public void WriteInt(string section, string name, int Ival)
public void WriteString(string section, string name, string strVal)

private void numericUpDown1_ValueChanged(object sender, EventArgs e)
{
    //业务功能代码
    //将值写入.ini文件的代码
}

//使用IniFile类的实例初始化
ConfigManager configManger = new ConfigManager(new IniFile(path));


//使用获取文件路径的委托实例初始化
ConfigManager configManger = new ConfigManager(new GetConfig(getPathMethod));

configManger.Add(checkBox1, “Section1”, “Name1”);
configManger.Add(comboBox1, “Section1”, “Name2”);
configManger.Add(numericUpDown1, “Section2”, “Name1”);

foreach (Control item in this.Controls)
{
    Type t = item.GetType();
    if(t == typeof(CheckBox) || t == typeof(ComboBox) || t == typeof(NumericUpDown))
    {
        configManger.Add(item,this.GetType().ToString(),item.Name);
    }
}

IList<string> errors = configManger.Init();

string error = configManger.Read(item)

configManager.Remove(item)

private string readTextBox(object item)
{
    //读取操作
}

private void bindTextBox(object item, bool remove = false)
{
    //这里要提供移除委托的方法，否则移除控件时保存操作不会从事件响应委托链上移除
    if (remove)
    {
        (item as TextBox).TextChanged -= this.TextBoxTextChange;
    }
    else
    {
        (item as TextBox).TextChanged += this.TextBoxTextChange;
    }
}

private void TextBoxTextChange(object sender, EventArgs e)
{
    //保存操作
}
configManager.AddReader(typeof(TextBox).ToString(), new ConfigManager.Reader(readTextBox));
configManager.AddEventBind(typeof(TextBox).ToString(), new ConfigManager.EventBind(bindTextBox));

configManager.RemoveEventBind(typeof(TextBox).ToString());
configManager.RemoveReader(typeof(TextBox).ToString());
