c# - 按 3 个值排序列表

Question

我有一个列表，我想按升序对 CategoryCounter、GroupCounter、QuestionCounter 进行排序。我怎样才能做到这一点？

public class CustomList
{

    private int _categorySequence = 0;
    private int _groupSequence = 0;
    private int _questionSequence = 0;
    private string _name = String.Empty;

    public string Name
    {
        get { return _name; }
        set { _name = value; }
    } 

    public int CategoryCouter
    {
        get { return _categorySequence; }
        set { _categorySequence = value; }
    }

    public int GroupCounter
    {
        get { return _groupSequence; }
        set { _groupSequence = value; }
    }

    public int QuestionCounter
    {
        get { return _questionSequence; }
        set { _questionSequence = value; }
    }
}

Answer 1

您可以使用OrderBy后跟ThenBy。

var result = MyCollection.OrderBy(x => x.CategoryCounter)
                         .ThenBy(y => y.GroupCounter)
                         .ThenBy(z => z.QuestionCounter);

Answer 2

嗯......我想，如果你可以做你想做的事情：

1. 首先使用一些排序算法
2. 如果发生碰撞，按第二个排序
3. 如果第二个发生碰撞，则按第三个排序。
