记一个C#排序

using System;

　　　　 var cs = Array.BinarySearch<ScoreInfo>(scoreInfos,scoreInfo3);//返回索引

    }
}
//针对C#程序设计成绩的ICompare实现
public class CSharpCompare : IComparer<ScoreInfo>
{
    public int Compare(ScoreInfo left, ScoreInfo right)

打印结果：

1-张三-12-24-36
2-李四-13-24-36
3-王五-14-33-32
3-王五-14-33-32
2-李四-13-24-36
1-张三-12-24-36
