Question

我有一个班级

public class GetRate : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;

    private string StockName;
    private decimal? VolumeOrdered;
    private decimal? BuyRate;
    private decimal? SellRate;        
    private DateTime? OrderedDate;        
}

另一个用webservice初始化它的类。

private static void Parse(List<GetRate> rates, XDocument doc)
    {
        XElement results = doc.Root.Element("results");

        foreach (GetRate getRate in rates)
        {                
     XElement q = results.Elements("rate").First(w=>w.Attribute"StockName").Value==rates.Symbol);

            rates. VolumeOrdered = GetDecimal(q.Element("VolumeOrdered").Value);
            rates. BuyRate = GetDecimal(q.Element("BuyRate").Value);
            rates. SellRate = GetDecimal(q.Element("SellRate").Value);
            rates.LastUpdate = DateTime.Now;
    }
}

现在我想在另一个类中使用它的值。怎么可能？我想用

 class ABC
 {
    VolumeOrdered* BuyRate;
     //Or
    VolumeOrdered* SellRate;
 }

需要帮助...... 在此先感谢...

您需要在其他类中可见的其他类中创建要访问的变量：

public class GetRate : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;

    private string StockName;
    private decimal? VolumeOrdered;
    public decimal? BuyRate;
    public decimal? SellRate;        
    private DateTime? OrderedDate;        
}

更好的是，你应该使用getter和setter：

public class GetRate : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;

    private string StockName;
    private decimal? VolumeOrdered;
    public decimal? BuyRate { get; set; }
    public decimal? SellRate { get; set; }        
    private DateTime? OrderedDate;        
}

调用另一个类中的一个类的数据c＃
