我有数据

column1   column2  column3 
Data101    Data2   Data3
Data100    Data20  Data355
Data10     Data2   Data3lh

表中的非结构化数据,没有唯一列,也没有索引

我想要最后一排

输出:

Data10     Data2   Data3lh

public Class Users{
    string UserName,
    List<UserDesktop> userDesktop
}

public class UserDesktop{
    int ID,
    string DesktopName,
    string type -- here Type value is A, B;
}

在这里，我必须找到分配了包含所有数据的 A 类用户变量的桌面的用户数。

List<Users> finalUsers = users.Count(s=>s.userDesktop.where(x=>x.type == "A"))

请让我知道正确的做法

List<Employee> employeeList = new List<Employee>();
List<Event> eventList = new List<Event>();

//Wanted to execute each foreach call asynchronously, to improve performance
foreach (var account in accounts)
{
    var context = await GetContext(account); 
    
    //following two await is depends on above result
    var employees = await _employeeService.List(context);
    var events = await _eventService.List(context).ConfigureAwait(false);
    //Question is how to execute above two await calls parallely
    employeeList.AddRange(employees);
    eventList.AddRange(events);
}

我想同时启动两个长时间运行的任务（员工和事件）。那么我们是否可以实现上述每个账户的并行执行来解决这个问题呢？
