在没有等待的情况下使用异步? [英] Using async without await?

问题描述

考虑使用异步而不等待.

认为您可能误解了 async 的作用.警告是完全正确:如果您将方法标记为异步但不使用等待任何地方，那么你的方法就不会是异步的.如果你调用它，所有方法内的代码会同步执行.

think that maybe you misunderstand what async does. The warning is exactly right: if you mark your method async but don't use await anywhere, then your method won't be asynchronous. If you call it, all the code inside the method will execute synchronously.

我想写一个应该异步运行但不需要使用等待的方法.例如，当使用线程时

I want write a method that should run async but don't need use await.for example when use a thread

public async Task PushCallAsync(CallNotificationInfo callNotificationInfo)
{
    Logger.LogInfo("Pushing new call {0} with {1} id".Fill(callNotificationInfo.CallerId,
}

我想调用 PushCallAsync 并运行异步，不想使用 await.

I want call PushCallAsync and run async and don't want use await.

我可以在 C# 中使用 async 而不使用 await 吗?

Can I use async without await in C#?

推荐答案

如果你的 Logger.LogInfo 已经是异步的，这就足够了:

If your Logger.LogInfo is already async this is enough:

public void PushCallAsync(CallNotificationInfo callNotificationInfo)
{
    Logger.LogInfo("Pushing new call {0} with {1} id".Fill(callNotificationInfo.CallerId,
}

如果不是不等待就异步启动

If it is not just start it async without waiting for it

public void PushCallAsync(CallNotificationInfo callNotificationInfo)
{
    Task.Run(() => Logger.LogInfo("Pushing new call {0} with {1} id".Fill(callNotificationInfo.CallerId));
}
