如何将文件提供给telnet(how to feed a file to telnet)

 
 
 有什么理由让它保持异步吗？ 
 
 
 那真的取决于你。 如果您确实需要利用能够扩展的异步操作，那么请保留它。 否则，如果不这样做，请使用同步API。 这完全取决于您以及您在代码库中实际使用的内容。 
 
 我理解你担心异步方法“一路走来”并且实际上改变你的整个代码库变成异步这一事实。 这就是为什么你应该这样做，只要它是值得的。 
 
 附注 - 您可以稍微修改您的代码以节省自己的异步状态机生成： 
 
private Task<List<stuff>> GetData()
{
    return _appCache.GetAsync("SiteStructurePages",
         () => _repository.GetSomeStuff());
}

 
 
is there any reason to keep it async?
 
 
That really depends on you. If you actually need to take advantage of asynchronous operations, which is being able to scale, then do keep it. Otherwise, if you don't, use a synchronous API. it's all up to you and what you actually make use of in your code base.
 
I understand the fact that you're worried about async methods going "all the way" and actually altering your entire code-base to become async. That's why you should do it as long as it's worth it.
 
Side note - you can slightly modify your code to save yourself the async state-machine generation:
 
private Task<List<stuff>> GetData()
{
    return _appCache.GetAsync("SiteStructurePages",
         () => _repository.GetSomeStuff());
}
