将“func<task>”传递给方法-调用func与lambda与async/await lambda之间有什么区别?

让我们考虑一下方法:

public static void FireAsyncAndForget(Func<Task> func)
{
    JoinableTaskFactory.RunAsync(func).FileAndForget();
}

async Task DoAsync()
{
    await SomeOtherMethodAsync();
}

下面的3个例子在代码的执行方式上有什么不同吗?

1. FireAsyncAndForget(DoAsync);
2. FireAsyncAndForget(() => DoAsync());
3. FireAsyncAndForget(async () => await DoAsync());
