我有一个类型为StackBuilder的列表：

public class StackBuilder
{
    private int quoteID = 0;
    private double price = 0;
    private double size = 0;
    public int QuoteID
    {
        get { return quoteID; }
    }
    public double Price
    {
        get { return price; }
    }
    public double Size
    {
        get { return size; }
    }
    public StackBuilder(int quoteID, double price, double size)
    {
        this.quoteID = quoteID;
        this.price = price;
        this.size = size;
    }
}

我正在尝试删除价格等于 NaN 的所有元素。这就是我所拥有的，但由于某种原因它不起作用。

BidStack.RemoveAll(item => item.Price == Double.NaN);
AskStack.RemoveAll(item => item.Price == Double.NaN);

有什么建议吗？

解决：

BidStack.RemoveAll(item => Double.IsNaN(item.Price));
AskStack.RemoveAll(item => Double.IsNaN(item.Price));
