控制台应用程序-在c#中从标准I/O读取非阻塞

本文关键字：读取标准应用程序控制台 | 更新日期: 2023-09-27 17:49:45

我想要一个来自控制台的非阻塞读取函数。我怎么用c#写呢?

Richard Dutton在他的博客上有一个解决方案:

while (true)  
{  
    if (Console.KeyAvailable)  
    {  
        ConsoleKeyInfo key = Console.ReadKey(true);  
        switch (key.Key)  
        {  
            case ConsoleKey.F1:  
                Console.WriteLine("You pressed F1!");  
                break;  
            default:  
                break;  
        }  
    }  
    // Do something more useful  
}

var buf=new byte[2048];
var inputStream=Console.OpenStandardInput(); //dispose me when you're done
inputStream.BeginRead(buf,0,buf.Length,ar=>{
    int amtRead=inputStream.EndRead(ar);
    //buf has what you need. You'll need to decode it though
},null);
