Question

Dictio是Dictionary<string, Grouped>。

Grouped是一个包含任务列表的类。

我想根据2个参数“name”和“computerName”选择一个任务。作为返回值，我想要一个任务对象（名称+ computerName给出1个任务）

我的代码：

var task = Dictio
  .Select(s => s.Value.Tasks.Where(( z => z.Name == task.Name && 
                                          z.ComputerName == task.ComputerName )));

Answer 1

var name = "SomeName";
var computerName = "ComputerName";

var tasks = Dictio.SelectMany(s => s.Value.Tasks) // flatten all tasks to one list
                  .Where(z => z.Name == name && z.ComputerName == computerName )); // query

// tasks will be a list of tasks, if you want only one of them:

var task = tasks.FirstOrDefault();
// task will be the first found task or null if no task matched your query
