Question

public class Car
    {
        public int TyresCount { get; set; }
        public int SpareTyreCount { get; set; }
        public int FrontTyres { get; set; }
        public int RearTyres { get; set; }
    }

    public class CarAssembly
    {

        public async Task<Car> Process(Car car)
        {
            car = await AssembleFrameAsync(car);
            //Option A
            SetTyreCount(car);
            //or Option B
            SetTireCountNonStatic(car);
            //or Option C
            await Task.Run(() => SetTyreCountAsync(car));
            car = await AssembleEngineAsync(car);
            return car;
        }

        public async Task<Car> AssembleFrame(Car car)
        {
            car = await httpclient.GetAsync("GetFrame");
            return car;
        }

        //Option A
        private static void SetTyreCount(Car car)
        {
            car.TyresCount = car.FrontTyres + car.RearTyres;
            car.SpareTyreCount = 1;
        }

        //Option B
        public void SetTyreCountNonStatic(Car car)
        {
            car.TyresCount = car.FrontTyres + car.RearTyres;
            car.SpareTyreCount = 1;
        }

        //Option C
        public void SetTyreCountAsync(Car car)
        {
            car.TyresCount = car.FrontTyres + car.RearTyres;
            car.SpareTyreCount = 1;
        }
        public async Task<Car> AssembleEngineAsync(Car car)
        {
            car = await httpclient.postAsync("assembleEngine");
            return car;
        }
    }

我有一个类 CarAssembly ，该类具有方法 Process ，该方法调用异步方法 AssembleFrame ，然后必须调用另一个方法来 GetTyreCount 是获取计数的一种非常简单的方法，如上所述，上面提到的三个选项OptionA，OptionB和OptionC就是调用此简单的CPU绑定方法的正确方法。即使我所说的选项不正确，也请提供您的想法是正确的方法。假定它是在WebAPI（无UI）中执行的类

Answer 1

在WebAPI上，应该使用选项A或B。如果不需要访问实例变量（例如记录器），请使用选项A。如果需要，请使用选项B。

一般来说，do not use Task.Run on ASP.NET。

异步方法执行流程，必须执行简单的CPU绑定操作
