        DateTime time = DateTime.Now;
        double price = 180.00; // IBM stock price
        StockInfo1 info = new StockInfo1 { Time = time, Price = price };
        stockData1.AppendAsync(Dispatcher, info);
    }

    public class StockInfo1
    {
        public DateTime Time { get; set; }
        public double Price { get; set; }
        public double Range { get; set; }
    }
}
}

我是C＃/ WPF的新手。想要跟踪/绘制许多股票（例如：IBM作为StockInfo1）。如何在不创建丑陋的StockInfo2，StockInfo3等的情况下整洁地完成任务？一直在寻找和尝试几种选择，但很多超出我对C＃的有限知识。感谢提前的任何方向/示例/代码片段

Answer 1

只需要一个股票类

public class Stock
{
    public string Symbol { get; set; }
    public ObservableCollection<StockInfo> StockInfos { get; } = new ObservableCollection<StockInfo>();
}    

public class StockInfo
{
    public DateTime Time { get; set; }
    public double Price { get; set; }
    public double Range { get; set; }
}

然后在主类

public ObservableCollection<Stock> Stocks { get; } = new ObservableCollection<Stock>();

不需要这个AppendAsync内容

Answer 2

你不需要StockInfo2 只需使用列表或数组

public List<ObservableDataSource<StockInfo>> StockList = new List<ObservableDataSource<StockInfo>>();

然后你可以使用

var info = new ObservableDataSource<StockInfo>>(new StockInfo {
    Time = DateTime.Now,
    Price = 20
})
StockList.add(info);

将新库存添加到您的列表

或者你编写一个函数来添加一个新的StockInfo

public void addStockInfo(Double price,DateTime time){
    StockList.add(new ObservableDataSource<StockInfo>>(new StockInfo {
        Time = time,
        Price = price
    });
}

C＃Class除了收藏
