我有一类与2串和1张（金额）。

I have a class with 2 strings and 1 double (amount).

类捐赠者

现在我有捐赠者填补了一个数组。 我怎么能按金额排序？

Now I have a Array of Donators filled. How I can sort by Amount?

推荐答案

如果您实施IComparable<Donator>你可以做到这一点是这样的：

If you implement IComparable<Donator> You can do it like this:

public class Donator :IComparable<Donator>
{
  public string name { get; set; }
  public string comment { get; set; }
  public double amount { get; set; }

  public int CompareTo(Donator other)
  {
     return amount.CompareTo(other.amount);
  }
}

您可以调用排序在任何你想要的，说：

You can then call sort on whatever you want, say:

var donors = new List<Donator>();
//add donors
donors.Sort();

在 .Sort（）要求你实现排序的的CompareTo（）方法。

The .Sort() calls the CompareTo() method you implemented for sorting.

还有没有拉姆达替代 IComparable的＆LT; T＆GT; ：

var donors = new List<Donator>();
//add donors
donors.Sort((a, b) => a.amount.CompareTo(b.amount));
