带有输入参数和输出的 Task.Run [英] Task.Run with Input Parameters and Output

问题描述

这很好用:

private void MainMethod()
{
    Task<bool> taskItemFound = new Task<bool>(ItemFound);
}

private bool ItemFound()
{
    //Do Work
    return true;
}

这有效但很丑，而且我不能传递多个参数:

This works but is UGLY and I can't pass more than one parameter:

private void MainMethod()
{
    var startNew = Task<bool>.Factory.StartNew(TempMethod, "cow");
}

private bool TempMethod(object o)
{
    return ("holy " + o == "holy cow");
}

我正在寻找一种解决方案，该解决方案将从具有多个输入参数的现有方法中为我提供一个 Task 并返回一个 bool.理想情况下，它看起来像这样:

I'm looking for a solution that will give me a Task<bool> from an existing method with more than one input parameter and that returns a bool. Ideally, it would look like this:

Task<bool> taskItemFound = new Task<bool>(ItemFound(param1, param2, param3));

推荐答案

您可以:

bool result = await Task.Run(() => ItemFound(param1, param2, param3) );

或者如果你真的想要它作为 Task:

Or if you really want it as Task<bool>:

Task<bool> t = new Task<bool>(() => ItemFound(param1, param2, param3) );
