VS2005 + Crystal Report 開發 Web 應用 (3) - 建立 Stock 類別與屬性封裝

Stock 類別實作

VS2005 要求類別放在 App_Code 資料夾，加入時會提示自動建立。類別必須為 public 才能被報表設計工具存取。

完整程式碼

public class Stock
{
    public Stock() { }
    
    private string _symbol;
    private double _price;
    private int _volume;
    
    public string Symbol
    {
        get { return _symbol; }
        set { _symbol = value; }
    }
    
    public double Price
    {
        get { return _price; }
        set { _price = value; }
    }
    
    public int Volume
    {
        get { return _volume; }
        set { _volume = value; }
    }
    
    public Stock(string symbol, int volume, double price)
    {
        _symbol = symbol;
        _volume = volume;
        _price = price;
    }
}
