TreatControlCAsInput问题。这是错误吗？ [英] TreatControlCAsInput issue. Is this a bug?

问题描述

仅遇到以下问题。如果 Console.TreatControlCAsInput = true;，则必须在ReadLine（）上按两次[enter]。

Just ran across the problem described below. If "Console.TreatControlCAsInput = true;", you have to press [enter] twice on ReadLine().

我在下面编写了一些演示代码。我以为该代码演示了.NET 4框架中的错误？

I've written some demo code below. I am correct in surmising that this code demonstrate a bug in the .NET 4 framework?

        Console.Write("Test 1: Console.TreatControlCAsInput = false\nType \"hello\": ");
        {
            string readline = Console.ReadLine(); // type "hello" [enter].
            Console.WriteLine("You typed: {0}", readline);
            // Prints "hello".
        }

        Console.Write("Test 2: Console.TreatControlCAsInput = true\nType \"hello\": ");
        Console.TreatControlCAsInput = true;
        {
            string readline = Console.ReadLine(); // type "hello" [enter].
            Console.WriteLine("You typed: {0}", readline);
            // Should print "hello" - but instead, you have to press [enter] 
            // *twice* to complete the ReadLine() command, and it adds a "\r" 
            // rather than a "\n" to the output (so it overwrites the original line)
        }

        // This bug is a fatal error, because it makes all ReadLine() commands unusable.

        Console.Write("[any key to exit]");
        Console.ReadKey();

推荐答案

它是已知问题，并且早在2006年就已在Microsoft Connect上进行报道。

It is a known issue with the Windows Console subsystem and has been reported on Microsoft Connect back in 2006.
