复制代码 代码如下:

static void main(string[] args)
{

    employee employee = new employee();
    //设置初始值
    list<employee> employeelist = new list<employee>();
    employeelist.add(new employee() { empid = "001", empname = "tony" });
    employeelist.add(new employee() { empid = "002", empname = "mack" });
    employeelist.add(new employee() { empid = "003", empname = "jon" });
    employeelist.add(new employee() { empid = "004", empname = "dawei" });
    employeelist.add(new employee() { empid = "005", empname = "jack" });
    employeelist.add(new employee() { empid = "006", empname = "abby" });
    employeelist.add(new employee() { empid = "007", empname = "carrie" });
    //指定置前排序元素
    list<employee> tosortlist = new list<employee>();
    tosortlist.add(new employee() { empid = "003", empname = "jon" });
    tosortlist.add(new employee() { empid = "005", empname = "jack" });
    tosortlist.add(new employee() { empid = "007", empname = "carrie" });
    //自定义 排序委托
    employeelist.sort((employee x, employee y) => (tosortlist.count(e => e.empid == y.empid) - tosortlist.count(e => e.empid == x.empid)));
}

public class employee
{
    public string empid
    {
        get;
        set;
    }

    public string empname
    {
        get;
        set;
    }
}

经过排序后将原本list中按001，002,003，排列的元素排序为003,005,007,001,002,004.。。。将指定的003,005,007，排列在list最前
