TreatControlCAsInput问题.这是臭虫吗?

刚刚遇到下面描述的问题。如果"控制台。TreatControlCAsInput = true;"，你必须在ReadLine()上按两次[enter]。

我在下面写了一些演示代码。我猜对了，这段代码演示了。net 4框架中的一个bug。

        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();
