Question

我有以下列表：

public class Address{
    public string Number { get; set; }
    public string Street { get; set; }
    public string Suburb { get; set; }
}

List<Address> MyAddressList = new List<Address>();

我想要做的是按郊区和街道对此列表进行排序。我已经看到我可以按其中一个属性（本例中为Suburb）排序：

MyAddressList = MyAddressList.OrderBy( x => x.Suburb ).ToList();

但我想按郊区然后街道排序。感谢

Answer 1

您可以使用ThenBy（或ThenByDescending）调用链接进一步排序：

MyAddressList = MyAddressList.OrderBy( x => x.Suburb ).ThenBy(x => x.Street).ToList();

Answer 2

您可以使用ThenBy

按顺序对序列中的元素进行后续排序。

http://msdn.microsoft.com/en-us/library/system.linq.queryable.thenby.aspx

MyAddressList = 
   MyAddressList.OrderBy( x => x.Suburb ).ThenBy(x => x.Street).ToList();

如果需要，您还可以chain multiple ThenBy。

Answer 3

您也可以像这样使用Comparison代表：

private int CompareAddress(Address first, Address second)
{
    if (first.Suburb.Equals(second.Suburb))
    {
        return first.Street.CompareTo(second.Street);
    }
    else
    {
        return first.Suburb.CompareTo(second.Suburb);
    }
}

然后：

List<Address> MyAddressList = new List<Address>();
MyAddressList.Sort(CompareAddress);

c＃排序自定义列表
