小编Kir*_*rzy的帖子

我读到void从C#async调用返回并不好.但我有以下情况:

public async void MainFunction()
{
    await DoSomething()
    await DoSomethingMore()
}

public void DoSomething() 
{
    //some code that I want to execute (fire and forget)
}

public void DoSomethingMore()
{
    //some code that I want to execute (fire and forget)
}

因为我只想要执行该函数而根本没有返回.我应该这样保留它,还是应该Task从DoSomething()返回？如果我将其更改为返回Task,因为我的代码根本不需要返回任何内容,我应该返回什么？

我有这个代码

public class ClassToTest
{
    private readonly IRepository repository;

    public ClassToTest(DI GOES HERE){...}

    public DoSomething() 
    {
        Task.Run(async () => {
            //some code
            repository.ExecuteAsync();
        }
    }
}

public class Repository : IRepository
{
    public Task ExecuteAsync()
    {
        using (var connection = new SqlConnection(DbConfiguration.DatabaseConnection))
        {
            return connection.ExecuteAsync(storedProcedure, parameters, commandType: CommandType.StoredProcedure, commandTimeout: Configuration.TransactionTimeout);
        }
    }
}

[Test]
public void TestMethod()
{
    var repository = new Mock<IRepository>;
    var classToTest =  new ClassToTest();

    classToTest.DoSomething();

    repository.Veryfy(p => p.ExecuteAsync(), Times.Once());
}

测试失败并显示此消息

模拟一次的预期调用,但是是0次:p => p.ExecuteAsync()

有谁知道为什么？

谢谢
