使用动作创建任务<T, T, ... n>多个参数

Create a Task with an Actionlt;T, T, ... ngt; multiple parameters(使用动作创建任务lt;T, T, ... ngt;多个参数)

问题描述

我想在包含 Action 的任务中添加多个参数.我查看了现有的堆栈溢出问题 Create a Task with an Action<T>

I want to add multiple parameter in a Task containing Action. I reviewed the existing stack-overflow question Create a Task with an Action<T>

请帮助我如何在 Task 的 Action 方法中传递多个参数

Kindly assist me how to pass multiple arguments in a Action method in a Task

Action<string, int> action = (string msg, int count) => 
    { 
        Task.Factory.StartNew(async () => 
            { await LoadAsync(msg, count); }); 
    };


Task task = new Task(action, ....);

动作方法是

public static async Task<string> LoadAsync(string message, int count)
{
    await Task.Run(() => { Thread.Sleep(1500); });
    Console.WriteLine("{0} {1} Exceuted Successfully !", message ?? string.Empty, (count == 0) ? string.Empty : count.ToString());
    return "Finished";
}

请帮助我如何创建异步方法的操作以及如何将操作添加到任务中.

Kindly assist me how to Create a action of an async method and how to add the action into the Task.

推荐答案

像这样传参数就行了.

Action<string, int> action = async (msg, count) => await LoadAsync(msg, count);
Task task = new Task(() => action("", 0)); // pass parameters you want

如果你也想得到返回值

Func<string, int, Task<string>> func = LoadAsync;
Task<string> task = func("", 0); // pass parameters you want

var result = await task; // later in async method
