从C＃中的标准I/O读取非阻塞读取＃

Question

我想从控制台读取一个非阻塞读取功能。

Answer 1

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); 

Answer 2

Richard Dutton对his blog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 
}
